Hike to the top of a collapsed stratovolcano in Arizona's alpine tundra for a view of the Grand Canyon (on a clear day).
On top of Arizona: a spectacular look toward the east at the Inner Basin sculpted by San Francisco Mountain avalanche that occurred as a result of caldera collapse, and the San Francisco Volcanic Field in the distance.

Trip Stats via Snowbowl Trailhead
Location: Coconino National Forest - Kachina Peaks Wilderness - San Francisco Mountains, Flagstaff, northern Arizona. Distance/Elevation gain: 4.8 miles from parking lot (9,266') to Humphreys summit (12,633') = 3,367' gain (9.6 miles out and back). Trailhead: From Flagstaff drive north on US 180 for 7 miles to FR 516, the Snowbowl Road. Drive 7.4 miles on this paved road to the lower parking lot of the Snowbowl facility. The trailhead is located at the north end of the parking lot. Forest Service info: Humphreys Trail #151) Factors that make this hike more difficult: high altitude. Date Hiked: October 7, 2024. Prominence: 6,039'. Maps/Apps: Humphreys Peak Quad topo map, AllTrails. Interactive Caltopo map of the San Francisco Peaks and Flagstaff Area. with our GPS tracks. Considerations and links: Mountain Weather Forecast - Humphreys Peak. Flagstaff Rangers District. Geology: Humphreys is the highest of the San Francisco Peaks (Agassiz and Aubineau are two others), of a much taller San Francisco Mountain, which was a large stratovolcano composed of layers of lava, cinders, pumice and ash that erupted over 900,000 - 400,000 years ago. After this, the top and northeast side of this stratovolcano collapsed in a gigantic avalanche that flowed out toward the northeast. Stratovolcanoes are steep because the extruding lava is high in silica (geology term is felsic - quartz and feldspar forming) and therefore has higher viscosity, so it solidifies more quickly, creating a steep profile.

The remnants of a much higher stratovolcano, Humphreys Peak stands higher than any other summit in Arizona, with an additional advantage of having the second-highest prominence. Prominence is a measure of the difference in elevation between the summit and the lowest point along the ridge that connects the mountain to a higher mountain (from surgent.net). Both Fred and I hiked this this summit 30 years ago, separately. The aspect I remember most, aside from the false summit, was the view of the Grand Canyon to the north. This time it was a bit too hazy to see the Grand Canyon, but I could see the Painted Desert in the distance. As with other summits, Humphreys has a couple of "false summits". In fact, on our way down, a guy hiking up was grumbling about the false summit he was on and that the trail was a bit hard to follow occasionally. But we knew what to expect this time: the first summit you see is not Humphreys; it's hiding behind it. The altitude is the most limiting factor of this hike, especially if you are coming from a lower elevation.
Our Hike
Trailhead to forest switchbacks (0 - 1.0 mile, 9,266' - 9,940') Forest switchbacks to saddle on Humphreys' south ridge (1.0 - 3.8 miles, 11,780') Ridge to Point 12, 297 (3.8 - 4.2 miles, 12,297') Point 12,297' to summit (4.2 - 4.8 miles, 12,633')
The Arizona Gondola of the Arizona Snowbowl Ski Resort is visible across the valley to the south as the trail progresses up to Humphreys' south ridge and a spectacular view to the east. Here, and the rest of the way to the summit, you see different views of the massive avalanche topography that occurred hundreds of thousands of years ago when the eastern flank of San Fransisco Mountain collapsed, leaving six peaks lining the ridge above it.
Agassiz Peak is one of them, a large peak to the right (south), and from what I read of other trip posts, illegal to climb unless there's snow to cover a federally-listed threatened plant, the San Francisco Peaks groundsel. It grows only in the alpine tundra of the San Francisco Peaks at 11,000 - 12,400' elevation. It thrives in the volcanic rock talus on Humphreys and Agassiz Peaks. We did see one sign - "Hiking off trail prohibited - $500 fine" at the ridge. At the saddle on the ridge, the Weatherford Trail heads southeast towards Agassiz, Fremont and Doyle Peaks that line this huge avalanche chute, which is referred to as the "Inner Basin." It looks so tempting to go back and summit these mountains, but for Agassiz it would have to be with snow cover. Now it's just a matter of hiking through a steep volcanic talus slope, arriving at a "false summit" before you actually get to Humphreys, another 0.5 miles, straddling the ridge with the inner basin to the east and cinder cones of the San Francisco Volcanic Field to the west. We got to spend more summit time than usual because of the great weather: sunny, pleasant and no winds! A jubilant group arrived with one South Carolina couple that had Humphreys on their peak list. We made a hasty retreat down the trail in anticipation of our celebratory beer. We walked around a vibrant Flagstaff downtown, after leaving our car at the hotel. Afterward, we met our Uber driver in front of an impressive climbing gym.
For the Geo-Curious: San Francisco Volcanic Field
Humphreys Peak sits in the middle of Northern Arizona's San Francisco Volcanic Field, which covers about 1,800 square miles. Around 600 volcanoes were produced in this field starting 6 million years ago. Many of the mountains between Flagstaff and the Grand Canyon represent this field. These eruptions "migrated" west to east, meaning the eastern eruptions were the youngest. What better place, besides a helicopter or plane, to see a lot of these volcanoes than the summit of Humphreys? Volcanism is usually associated with tectonic plate boundaries, like with Mount St. Helens or Mount Rainier or Kilauea in Hawaii. This volcanic field occurs on the border of the Colorado Plateau and the actively stretching (extensional) Great Basin and Range Province. Stretching causes a thinning of the Earth's crust, which in turn brings warm mantle rock closer to the surface. The resultant depressurization and increased heat of this rock was the impetus for the San Francisco Volcanic Field and its many volcanoes. Volcanic rock color gives a clue as to what type it is. The more silica it contains, the lighter and thicker (more viscosity) it is. Basalt is black and has the lowest amount of silica, with larger amounts of iron and magnesium, and is the most prominent rock making up the San Francisco Volcanic Field's volcanoes. Andesite, a dark grey rock, has an intermediate silica amount, and is the prominent rock of Humphreys and Aggasiz Peaks. Light grey rhyolite is the most silica-rich rock and therefore is more viscous.
Picture Canyon and the Northern Sinagua Petroglyphs
Long before Flagstaff's vibrant downtown, the Sinagua (sin = without, agua = water) people inhabited northern Arizona between 500 - 1450 AD. They were hunters and gatherers with some agricultural practices. We stopped by Picture Canyon Natural and Cultural Preserve in Flagstaff to find the Northern Sinagua petroglyphs, one of which is a waterbird. We found this cluster of petroglyphs on basalt boulders along the Tom Moody Trail, next to Rio de Flag, a permanent stream, where perhaps the Sinagua saw cranes or herons. The "zig-zag" petroglyph may represent lightning, water, or mountains. Check out photos of these petroglyphs at the end of this post. A 1.5-mile section of the Arizona Trail treks through this preserve.
More to Explore
As usual, with each hike we do, we find more to do, more places to explore. We're in our early 60's, gratefully healthy, and trying to get as many summits and expeditions in as possible before we can't. We've lost a little speed, joints hurt a little more from our earlier hiking days, but we still take advantage of our good health and keep challenging ourselves. Life is short - get out there (put the phone away) for mind, body and spirit!

Sweet single track in the Kaibab Plateau's glorious high forest. Related Riding instead of Hiking We decided to switch up our usual mode of adventure - hiking - and get on our mountain bikes. After our epic Grand Canyon rim to rim in one day journey a few weeks ago, we noticed the beauty around Jacob Lake and GC's north rim in northern Arizona. Only a few hours drive from St. George, Utah, we got out of the heat to explore the cool, aspen-filled forest on the Kaibab plateau. So many aspens that it reminded me of Colorado high country. We stayed at Kaibab Lodge, five miles from the entrance to the north rim of the Grand Canyon National Park in a spartan "hiker's" cabin, the last place available there. Maybe a rim-to-rim hiker had cancelled at the last minute. The dinner and breakfast buffets were a bit spendy, but then again this is a pretty remote location. The Arizona National Scenic Trail links Mexico to Utah through 800 miles of prime Arizona deserts, mountains, and canyons. It's divided into 43 sections, or "passages." At the Mexico border, it begins in the Huachuca Mountains, trekking through grasslands to gain 3,000 feet to a ponderosa pine forest. The final passage is through Buckskin Mountain to the Utah border, where you can see the Vermillion Cliffs. It's open to hikers, mountain bikers and equestrians. We rode a gorgeous section of this trail through pristine forest and meadows in the Kaibab National Forest on a splendid single track to a viewpoint of the east rim of the Grand Canyon, making a loop by riding back on perfect gravel roads. No other vehicles - we had it to ourselves. The day before this, we just picked gravel roads to explore and ended up at an old cabin, possibly a line shack for ranchers. Our friend Jeff is an avid mountain biker. We hiked the rim to rim trail with him. When I showed him photos of this single track, he said, "Looks great. Let's go." That's the spirit! Looking forward to another northern Arizona adventure! A journey through one of the World's Seven Natural Wonders. Standard north → south route for Grand Canyon Rim to Rim in one day (North Kaibab Trail and Bright Angel Trail)
Total Distance = 23.5 miles North Kaibab Trail = 14 miles/5,700 feet loss. Bright Angel Trail = 9.5 miles/4,350 feet gain. Note: I've seen various estimates of "net elevation gain" that are higher. Since there is not any major regaining of lost elevation, I am estimating gain by difference between Colorado River and south rim. Elevations: north rim = 8,200 feet, south rim at Bright Angel Trailhead = 6,850', Colorado river = 2,500'. Date Hiked: May 23, 2024 Total elapsed time: 10:58 hours. Geology: The deepest rocks are metamorphic Vishnu Basement rocks on the lower part of North Kaibab trail as it enters the Box and Phantom Ranch and at Colorado River (Brama Schist, granite intrusive volcanics, pegmatite and aplite dikes). These are crystalline rocks (1.7 billion years), formed during Early Proterozoic time when continents were colliding, causing compression and mountain-building (orogeny). Theses are jumbled, interlayered shists and gneisses. Rim to Rim Resources: NPS: Critical Backcountry Updates - Grand Canyon NPS: Grand Canyon Backcountry Trail Distances Arizona State University. North Kaibab Trail - Nature, Culture and History at the Grand Canyon. Considerations: Fred and I recommend anyone undertaking this hike should train and be able to walk at least 15 miles continuously and hike 4,000 feet of elevation gain. We hiked this 23 years ago with 100-degree temps at Phantom ranch which slowed us down, but we had experience hiking in hot weather. "Endure. In enduring, grow strong." - Chris Avellone "It is a lovely and terrible wilderness, such a wilderness as Christ and the prophets went out into; harshly and beautifully colored, broken and worn until its bones are exposed . . . and in hidden corners and pockets under its cliffs the sudden poetry of springs." - Wallace Stegner Epic Adventure We did it! Three months of training on southern Utah trails, in St. George and Zion National Park, and on the Skyline Trail in Palm Springs helped Jeff, Fred and I conquer the Grand Canyon rim to rim hike. Two things helped us: training for distance and at least 4,000-foot of elevation gain, and we were lucky with weather. It was cooler than usual! To observe the Grand Canyon, one of the seven natural wonders of the world from its rim is a memorable experience. But to walk all the way through the depths of it - almost 24 miles from north rim to south rim along the clear and roaring Bright Angel Creek is epic. Your ability to tolerate a 50 or 60-degree temperature variation, drink enough water, and climb steep, relentless switchbacks will be tested. We took longer to do this hike this time (just shy of 11 hours), compared to our last time 13 years ago (9:50). I felt really tired the last mile up to Bright Angel Trailhead. I think I slowed Jeff and Fred down a bit! North Kaibab Trail → Phantom Ranch Lindy dropped us off at North Kaibab Trailhead on the north rim at 6:00 a.m. As we descended from a fir, spruce and ponderosa pine forest into a rocky color-layered paradise, she drove around to the south rim, descended 4 miles on the Bright Angel Trail to meet us later in the day. In the shadow of the north rim, we walked along verdant Roaring Springs Canyon to the bright yellow light below, reaching Supai Tunnel, the first restroom and water stop, at 1.7 miles. Wild roses bloomed against yellow and red walls. We didn't need a water re-fill until 5.4 miles down the trail at Manzanita Rest Area, a beautiful spot past Roaring Springs. We powered our way down the steep portion, through the wide Bright Angel Canyon, tracing the clear and loud Bright Angel Creek with its occasional waterfalls, hiking through Cottonwood Campground. The prickly pear were so full and healthy; it seemed the creek was flowing much more than we remember from our rim to rim hike 13 years ago. It appears the southwest has had more rainfall in the past few years. We hiked rim to rim 23 years ago and then again 13 years ago and it seems Bright Angel Creek was higher this year. We were happy to see Bright Angel Campground and Phantom Ranch at the bottom of the canyon where we re-filled our water and made sure to drink electrolytes. The temperature was 85 degrees. We took 20 minutes in the shade to eat and muster the energy to start the long, warm and steep hike to the south rim. The dark red, brown and grey Vishnu Basement rocks are one of my favorites of this hike, as you enter the core of the Grand Canyon. It forms the rough, contorted, massive base for the prettier rock layers above. It's not often that you get to walk in some of the Earth's oldest rocks; in this case the Vishnu schists, gneiss and granite are 1.7 billion years old. You get to see the rapids of the green Colorado River through the mesh floor of the long suspension bridge as it passes a huge swirling eddy near the shore, delivering you to the Bright Angel Trail and a long, arduous hike out.

Phantom Ranch → Bright Angel Trail Water stops along the Bright Angel Trail
We finally reached Havasupai Gardens, our last water stop (we knew the resthouses above did not have water) with 4.7 more miles to go! Dousing my hat in the cold water from the "community" faucet and letting it drip down my head felt so good! Shortly after eyeing the south rim's steep cliffs above that will be our trail, we resumed and were excited to see Lindy, who had descended 4.5 miles to meet us. Climbing higher, along Garden Creek, legs are tired, yet the terrain gets more challenging. We step over countless old juniper logs and rock bars used to stabilize the trail on forever switchbacks. We are trying to make it in under 11 hours. Dozens of short-distance south rim hikers congest the last half-mile. Don't want to lose momentum. Endure and grow stronger! Lindy spotted an incredible sandstone boulder along the trail that has fossilized tracks in it. They are the oldest vertebrate tracks in the Grand Canyon and the earliest evidence of vertebrate animals walking on sand dunes. They date to 300 million years ago, when Arizona was a coastal plain near the equator. This article in Smithsonian has a great illustration of how this reptile walks laterally, creating the diagonal footprints: Fallen Boulder at Grand Canyon reveals Prehistoric Reptile Footprints. Fossilized footprints found in Manakacha Formation - 313 million years old. And then the land above the canyon opens up and we arrive at the rim - WE'VE DONE IT!! We walk victoriously to the Bright Angel Trailhead sign where Lindy snaps our photo. Margaritas, beer, and burgers follow. I'm grateful we trained for this epic hike. I'm even more grateful that I am able to do this hike and witness this natural wonder - up close and personal, step after step, one foot in front of the other. Standard route for Grand Canyon North Rim to South Rim in one day (North Kaibab Trail and Bright Angel Trail) Distances/Elevation gain/loss: North Kaibab Trail = 14 miles/5,700 feet loss. Bright Angel Trail = 9.4 miles/4,350 feet gain. Note: I've seen various estimates of "net elevation gain" that are higher. Since there is not any major regaining of lost elevation, I am estimating gain by difference between Colorado River and south rim. Elevations: north rim = 8,200 feet, south rim = 6,850', Colorado river = 2,500'. All Fired up! As Pat Benatar's song goes, we're "All Fired Up" for next week's Grand Canyon rim to rim hike! Her song is a fitting accompaniment to the goblet squat video below. Fred and I needed elevation training, so we went to Palm Springs, my old stomping grounds, and hiked the Skyline Trail for a gain of 4,700 feet, the same Bright Angel Trail gain on the south rim of the Grand Canyon. We encountered too much snow at 8,000 feet in the Pine Valley Mountains just to the north of St. George, preventing a good elevation gain. My last post, Grand Canyon Rim to Rim In One Day: Training in St. George, Utah, explains how we got creative with emulating distance and elevation. We did great on the Skyline; we're now ready for the big hike!
New goal: hike to the tram this October with some of our hiking buddies. Oh, the nostalgia and the beauty of this mountain! I'm grateful that I can still be hiking it 31 years later - let's say that the Advil this time was very helpful! La Verkin Creek Trail to Kolob Arch - Zion NP This long hike features attributes found in Zion National Park's main canyon, including an arch, sandstone cliffs and a river but without the throngs of people. It's in the northern Kolob Canyons section, has a spur trail to impressive Kolob Arch, and also meets up with the Hop Valley Trail, a route to the main Zion Canyon. We hiked 7 miles in to Kolob Arch and back for a total of 14 miles, the same distance as Grand Canyon's North Kaibab Trail. It drops down from the parking lot at Lee Pass Trailhead into the La Verkin Creek drainage. The same mileage as our Skyline Trail hike, but not nearly the same elevation gain. We've got one more training hike on Zion's West Rim Trail this week with Lindy and Jeff, and then we should be good to go for the Grand Canyon. We are lucky to have such inspirational places, some of the most beautiful on Earth, in which to train! Strengthening exercise for powerful hill climbing: Goblet Squats I have found that since I started doing CrossFit and working on strengthening my legs, I have more stability and power for steeper hiking. Goblet squats can be done with a kettlebell as well as two dumbbells, each resting on your shoulders. Strengthens your core (trunk) muscles, glutes and hips. Points to remember:

On May 23, we will be walking Grand Canyon from its north rim to its south rim in one day - again. Fred and I first hiked this 23 years ago, to celebrate birthday #40 for both of us. We hiked it on our 50th. We talked about doing it for our 60th, but it wasn't until our friend Robin asked us to go that we got our motivation to train for rim to rim #3. Jeff will do it too, and Lindy will train with us but when it comes to the big day, she has generously offered to drop us off at the north rim and drive all the way around to the south rim to pick us up. Since January, Fred, Jeff, Lindy, Robin and I have been hiking the most challenging trails near St. George, Utah and in Zion National park. Creative planning like linking trails together ensures optimal distance and elevation training. We need to be able to cover 23 miles and a 4,500' gain for rim to rim. Just when your legs are tired from descending 14 miles on North Kaibab Trail, you face the biggest challenge: climbing up Bright Angel Trail for another 9.4 miles. And temperatures on the climb out can be hot, which was the case when we did this hike 23 years ago. We ended up soaking our hats in streams on the way up to cool off. Fred drank 9 liters of water! The next day, we hiked back to the north rim. Some of Our Training Hikes
Strengthening for Hill Climbing - Walking Lunge with Overhead Weight Climbing out of the Grand Canyon requires strong glutes! The most important function of your gluteus medius during hiking is to stabilize your pelvis to keep it level while standing on one leg (stance phase of walking). The stronger they are, the better protection for your knees, and the more efficiently they work, the less energy you waste. Walking lunges challenge your glute and core strength. Holding a weight over your head adds more challenge to your core musculature including abdominals and back extensors, as well as your shoulder girdle stabilizers (rhomboids, trapezius, serratus). Good training for scrambling hikes where you have to use hands to propel up rocks. Action: Hold dumbell or kettlebell overhead with elbow straight, next to your ear. Or, you could hold the weight in a "goblet" position next to your chest. Take a large step forward, that knee should not go ahead of your foot. Opposite knee taps the ground. Squeeze glute on stance leg to raise to lunge with opposite leg. Here's some scenes from three of our training hikes: Snow Canyon from Bottom to Top and Then Some: Berm Trail to Joan's Bones (12 miles RT, ~1600' net gain) Berm Trail → Padre' Canyon Trail → Red Sands Trail → West Rim Trail → Lava Flow Trail → Whiterocks Trail →Joan's Bones → car at Whiterocks Trailhead. Living near Utah's Snow Canyon State Park sure has its advantages. Each time I hike in this Navajo Sandstone paradise, I love it more. We started near where we live, caught the berm trail and walked to the Whiterocks Trail on the north side of the park, then walked east to almost the top of Joan's Bones. This route features gorgeous pools in cross bedded sandstone, soaring orange and red towers, petrified sand dunes, and pristine white sandstone slickrock strewn with black basalt boulders. Joan's Bones hike is on AllTrails (misspelled as "Jones Bones"). Snow Canyon training! Robin, Lindy and Jeff at top of Padre' Canyon.

Zion National Park - West Rim Trail to Horse Pasture Plateau (10 miles, 3,000' gain). Right after the shuttle service opened in early March, Lindy, Robin, Jeff and I headed to Zion to get some elevation training in. Starting at the Grotto Trailhead, 4,300' elevation, we hiked up West Rim Trail, past Angels Landing to the entrance into Horse Pasture Plateau at 6,713', at the intersection with Telephone Canyon Trail. After regaining ~ 300' of elevation loss to and from, I calculated our gain to be ~3,000 feet. We hiked on some icy snow. Down in the canyon and at the plateau, temperatures were a bit chilly. Zion was not especially busy with visitors that day. We celebrated afterwards in Springdale with beer and burgers at Porter's restaurant.

Ivins and Santa Clara, Utah: Suicidal Tendencies Trail and the "Badlands." The "badlands" is my nickname for the landscape west of Land Hill in Ivins, and east of the Beaver Dam Mountains because it reminds me of South Dakota's badlands. A spectacular view of this formidable-looking red and white striped land cracked by crooked canyons and washes and plateaus with well-established biological soils can be savored from the top of Land Hill. We hiked Wittwer Canyon, a major tributary that washes into Santa Clara River. Fred and I put together a 10-mile hike that linked the petroglyph trails on Land Hill to cross the Santa Clara River, to wander through the "badlands" to find a way to link to the Barrel Roll Trail in the Cove Wash Trails. In just one hike, Fred and I saw all the "cool stuff on this trail," (see photos below) and then some. A conglomerate boulder hanging on the steep wall under Land Hill looks like it has embedded dinosaur tracks. I called the local paleontologist; stay tuned!
We're fortunate to have Colorado Plateau hiking to the east of us and Mojave Desert hiking to the west. One day we hiked the 11-mile Suicidal Tendencies, a popular mountain bike trail with scary drop-offs. The more we hike this part of Utah, the more we find to explore. Not only are the views magnificent - black lava flows blend with red and orange cliffs, signs of past cultures and geological events adds a lot character to this part of southern Utah. My next post (rim to rim training, part 2) will highlight another Zion hike and Red Mountain Traverse. Getting Ready for the Big Day! Keep On Exploring!!!

One of the characteristics I look forward to with Tucson hiking is the wide flora variety and diversity. Along this 2,500-foot gain, Esperero Trail passes through three biomes, or habitats identified by their dominant life forms: Sonoran desert scrub, desert grassland, and Madrean evergreen woodland. The most obvious change happens after the steep climb to Cardiac Gap, at 4,400 feet, when saguaros and creosote have given way to oaks and grass. We arrived at Esperero Canyon's Bridalveil Falls after six miles of warm hiking and enjoyed the cold water dripping and spraying off the rocks. The falls must look like a veil during run-off after a storm, but at the end of April, they were reduced to small rivulets. The canyon here is wildly picturesque with huge rounded and dike-streaked boulders, pinyon pines and oaks, wildflowers and towering rock formations above. Yuccas are interspersed among junipers. If you keep climbing up-canyon, in another mile, you reach Cathedral Rock Trail, which heads northeast. Esperero Trail continues west toward Window Peak. Our Hike We parked at the large overflow parking lot for Sabino Canyon Recreation Area and began walking southeast past trailhead signs. (However, there is a shorter trail from the north end of the overflow lot; it heads north to meet up with Esperero Trail, avoiding the picnic area). The mileage that follows is from the trail that we took.

Trip Stats Overview: Walk up Finger Rock Canyon, keeping its namesake spire in view, among many saguaros and ocotillos followed by a steep, rocky climb along the canyon's east wall. At a grassy plateau, arrive at the path to Finger Rock. Keep climbing, passing Linda Vista, finally entering into a forest of alligator juniper and ponderosa pines.

Native peoples: Desert Archaic (2500 BC - 200 AD). Followed by Hohokam, who were "masters of the desert" until AD 1450, and O'odham peoples who still inhabit southern Arizona. O'odham means "the people". History: Named after Frederick E. Kimball, a land developer who influenced the building of road up to the Santa Catalina's highest summit, Mt. Lemmon. The Finger Rock Canyon trail to Mt. Kimball, one of the highest in the Santa Catalina Mountains, treks through gorgeous Sonoran landscape, meandering through wash and canyon lowlands, close to saguaros, gaining 400' in the first mile. That easy grade ends abruptly at mile two, when you encounter the first of many rock steps on a steep trail that climbs an average of 950' per mile to the summit. The south summit slope bestows a birds-eye view of Tucson, the north side a perched outcrop view of canyons below your feet and the rugged peaks of the western Santa Catalinas. Fred and I have been hiking this mountain ever since we started visiting Tucson to get out of Idaho high country's somber and snowy springs. This established Class 1 trail was a welcome change from the past few months of non-trail, route-finding, scrambling ascents in Utah and Nevada. Great to not have to navigate or continuously hunt for a route or the trail, but instead let the trail take us to the top. On this trip, we first stopped near Kingman, Arizona to attempt Mt. Tipton, but the unmarked 3,500' gain entailed miles and of shrubby terrain clogged with scrub oak and junipers, so we turned around. Islands in the Sky The ability to see the changing scenery of multiple life zones is one of the great features of southern Arizona hiking. The rewards are saguaros and yuccas at the beginning and end, and pine and juniper at the top of your hike, if you are willing to make the thousands-of-feet elevation journey. The Santa Catalina Mountains are but one of the many "sky islands" that rise above the desert. From the Chiricahua mountains in southeastern Arizona to the Sierra San Luis Mountains in Mexico's Chihuahua mountains, these unique, rugged environments support some of the highest levels of biodiversity in the world. Below is a summary of what I learned about biomes and sky islands. I also wrote about this in my Tanque Verde Peak - Saguaro Wilderness post. Southern Arizona mountains are a hiker's paradise. With waterfalls, rugged gneiss and granite rock outcrops to climb over, and wildflowers in spring that represent all of the color spectrum, this desert is surprisingly lush. It is a spectacular land where all elements work together in harmony through monsoons, rains, and killer heat waves, and cool winters. On Mt. Kimball's descent, the other side of the canyon is strewn with hundreds of saguaros clinging to rocky ledges, illuminated by the setting sun. This sight makes you forget about your tired legs. Hike Summary (GPS tracks at end of this post)
Frost gelato has become a Tucson post-hike tradition! Biomes of the Sonoran Desert
The Santa Catalina Mountains are in the Arizona Uplands, the highest and coldest portion of the Sonoran Desert.
Biome - "Coarse ecological units based on the phenology, lifeform, and physiognomy of the dominant vegetation. - Sonoran Desert Inventory and Monitoring Network - National Park Service. Biomes are determined primarily by temperature and rainfall, and are based on vegetation because plants are easily recognizable components of a biological community. (Dimmitt, 2015). Biomes of Sonoran Desert Network Parks
-from Sonoran Desert Inventory and Monitoring Network - National Park Service Desert
At around 3,000' elevation, the first mile or so of this hike begins where the desert biome is transitioning into the thornscrub biome. It wanders through a gorgeous landscape of saguaros, cholla, barrel cactus, and yucca succulents as well as mesquite, creosote bush and paloverdes shrubs. A great biome because plants are tough yet beautiful at the same time. Tough because plants have devised strategies to help them survive, such as thorns as a physical defense against predators, and hair on leaves to shield the relentless sun. Thorns and bristles act to shade and insulate certain crucial parts of cacti. Creosote bush adapts to the hot sun with wax-coated leaves to avoid loss of water. Thornscrub Before ascending the canyon wall at ~ 3,500', the landscape is transitioning to this biome, continuing with mesquite trees and catclaw (acacia) shrubs. Thornscrub has short trees with cacti, and is denser than desert biome. Vegetation grows lush with a lot of wildflowers. The climate is nearly frost-free (tropical). Plants shed leaves during dry season (drought-deciduous). Semi-desert grassland As the trail climbs just past 4,000 feet, a noticeable change in vegetation occurs: saguaros become scarce as the ridge is dominated by ever-increasing fields of bunchgrasses, oak and juniper. Calming, muted and soft neutral grey/greens replace bright primary colors of the lively, unrestrained desertscrub. Sotol, creosote and agave mix with a diverse array of grasses. As the trail gradually climbs, junipers become more prevalent. This land supports more succulents and shrubs. Hot pink Parry's penstemon add color to this landscape. Madrean Evergreen/Pine/Oak Woodland At the intersection with the trail to Finger Rock, ~ 5,200', larger trees such as alligator juniper appear. Evergreen oaks like Emory oak and Arizona white oak along with Mexican pinyon pine dominate this biome, named after its origin in the Sierra Madre mountain range that runs through Mexico and along the Gulf of California. These are subtropical woodlands. Temperate Forest A unique characteristic of the Sonoran temperate forest biome, officially beginning at around 6,000 feet elevation, is the cohabitation of lower-elevation desert plants, such as the yucca with spruces, pines, firs and maples. Species diversity reigns, although seemingly not to the degree of the desertscrub biome. Temperate forests are very cold-hardy and confined to cooler sites above the Madrean evergreen woodland. One of my favorite parts of this trail is where it crosses the creek to climb up to the intersection. The forest has some Ponderosa pines (reminds me of Idaho). At the top of Pima Trail, just below Kimball's summit, there are large alligator junipers to admire.

Hike Summary
We started on the Yetman Trailhead, not far from Golden Gate Mountain, instead of the Sarasota Trailhead which is closer to Cat Mountain so we could spend as much time as possible walking through this beautiful Tucson Mountain Park encompassing much of an ancient caldera, and weave around thorny saguaros and jumping chollas. We had also started at the Yetman trail a few days before, when we hiked three high points in this park: Golden Gate Mountain, Little Cat Mountain and Bobcat Ridge. All four peaks could be summited in one long day. Golden Gate Mountain's southeast slopes and cholla. Fred and Scott near Yetman trailhead under the north cliffs of Golden Gate Mountain Reach the saddle between Golden Gate Mountain and Bren Peak at 0.4 miles from Yetman trailhead, an excellent place to get a perspective on three high points: Bobcat Ridge, Little Cat Mountain and Cat Mountain. A textured green carpet sweeps down valley and up the slopes of these brooding, rugged mountains. The only thing that distracts from this scene is the housing development in the valley to the west. This pleasant view makes it difficult to imagine the sudden event of a magma chamber spewing the searing ash that formed this ancient caldera landscape. Tucson Mountain Chaos is the term given by geologists to the valley rocks that underlie the Cat Mountain Tuff, the compacted ash that forms these peaks. There is no definite answer to the thousands-feet thickness of this Cretaceous-age tuff. Were these rocks below the Cat Mountain Tuff rafted from deeper levels by the rising magma? Or, was this rock caused by a landslide in a caldera that had accumulated the tuff? To make the geologic puzzle even more complicated, spreading of the Earth during Basin and Range faulting makes the geologist's task of identifying the age relationship of the rocks more difficult. Yetman Trail heads to three summits from left to right: Bobcat Ridge, Cat Mountain in middle horizon with Little Cat in front of it. At 1.6 miles, Yetman intersects with Sarasota Trail. Bobcat Ridge is gained by going left and staying on Yetman Trail. For Cat Mountain, turn sharp right (south) onto Sarasota. In 1.4 miles, Explorer Trail intersects with Sarasota. You can hike on either trail to get to Cat Mountain. On our approach, we took Explorer Trail which wraps around the base of Little Cat Mountain for 0.8 miles to meet up again with Sarasota and also Starr Pass Trail. The worn-out "You are Here" red dot marks the intersection of Sarasota and Explorer Trails. Our route: Explorer (pink) trail to pass under the north flank of Cat Mountain. Arizona Barrel Cactus Cat Mountain from Explorer Trail on its north side. We went up low saddle to the left of the summit block to gain lower ridge. From our vantage point on the Explorer trail, we could see the gentler rise of Cat Mountain's east ridge. The three-trail intersection (Starr Pass, Explorer and Sarasota) is well-marked as are other intersections in this well-cared-for park. We continued on the Explorer trail for 0.6 miles until we saw a manageable route to the ridge, leaving it earlier than the standard cairned route (1.0 miles past 3-way junction), making our own path. A sea of detached teddy bear cholla branches, those little mobile yellow ovals armored with extremely sharp spines made us pick our footsteps carefully. However, I wasn't careful enough; one jumped up and stuck my pant leg to my calf. I remembered a hike many years ago when we used a metal comb to remove a cholla piece from a dog's leg. Scott and Fred somehow got the prickly thing off me and we resumed our cross-country hike with no serious injury except for a few red spots on my skin. The day grew colder and cloudier. The broken dark red and tan rocks deposited on the slopes from the tuff cliffs above crunched under our boots. The occasional cactus spine scraped against our packs and in some cases grabbed on. Three-way intersection. From here, exit Explorer Trail for more difficult ascent up Cat Mountain's northwest ridge. "Standard" and less difficult route leaves Explorer 1.0 mile after this intersection. "Teddy Bear Cholla" Cylindropuntia bigelovii After getting off Explorer, we looked for the best way up. Rocks formed a natural staircase. Four or five Coues Whitetail deer perched far above on steep cliffs stopped to watch us, curious at three humans stumbling through the cacti. The ridge walk was straightforward and it felt good to follow its natural route and rhythm, using hands when needed. We came upon cairns marking the final ascent to the summit and a complete change of view of the open sky and the sprawl of Tucson far below us. There's just one Class 3 crack with mild exposure to navigate, with just enough ledges to place feet and hands. Frequent rock cairns mark an obvious path. Picking our way to Cat Mountain's east ridge. Christmas Cactus Saguaro and cholla garden below last summit approach Scott ascending the last part of ridge climb Sweet cactus garden before final ascent. Fred on the summit of Cat Mountain Golden Gate Mountain on the right; Yetman Trail goes through the saddle to its right. Every ridge scramble, every summit has its own unique personality. The scramble up Cat Mountain's east ridge is challenging yet not scary, exposed but safe, with the right amount of rocks and cactus gardens making it aesthetically friendly. You're never bored with looking at saguaros and chollas because with each one, there is a different size or form. This summit has one very unusual feature - a plastic white boulder that houses a radio repeater. Looking at Cat Mountain from Tucson area, you would not suspect the spacious flat areas on its summit. A steady cold wind cut short our time lounging on the top, but we got a good look at Golden Gate Mountain to the northwest and the steep drop-off to the south. As we walked down, the clouds closed again, the temperature dropped, and the wind chilled. We hiked back via Sarasota Trail at the three-way intersection. We added another summit to our "three friends who like to hike" resume', and more stories for reminiscing. This will go down in the books as one of our more mellow hikes together. Never stop climbing mountains! Scott and Fred Looking at Santa Catalina Mountains north of Tucson and Rincon Mountains on right horizon. Fred and Sue on Cat!

Net elevation gain to summit = 2,000'. Difficulty: Moderate effort on defined trail, moderate-strenuous off-trail Class 2+ with one Class 3 pitch near summit. Experience with off-trail navigation necessary. Reference: We used Earthline's hike directions. Maps: Green Trails Maps Santa Rita Mountains (#2962S), our GPS tracks (below). Considerations: No permit, no trail register. Driving Directions: Trailhead. Leave Interstate 19 at the Canoa Road Exit near Green Valley. Take the east frontage road 3 miles south to Elephant Head Road and turn east 1.6 miles to the Mt. Hopkins Road. Drive 4.5 miles to FR 183. Turn north on this dirt road about 2.4 miles to a circular parking area with a large oak - just before the road crosses the streambed. Park here and travel back down the road a few paces to a sign that marks Trail #930 on right (north) side of road. Coordinates at parking: 31.6956 , -110.9288. Geology: Elephant Head Quartz Monzonite (Cretaceous ~70 Ma). Not to be mistaken for granite which contains > 20% quartz, monzonite contains 5-20% quartz. Large grains indicate slow cooling below Earth's surface. Flora: Desert grassland and oak-grassland biomes of Arizona's sky island region. *** 1/29/23: I received a comment from someone who hiked this trail last year - she saw forestry employees who told her to remove any elephants she might find on this trail in order to keep this beautiful area more pristine. Hike Summary
"Mountains complement desert as desert complements city, as wilderness complements and completes civilization." - Edward Abbey - from Desert Solitaire Our Hike On our first attempt at summiting Elephant Head Peak, a huge winter storm was blowing into southern Arizona, so by the time we reached the saddle just below the exposed ridge to the summit, we staggered against a roaring wind bent on toppling us over. We had to go back down. The storm produced a thick white blanket over the tops of the Santa Catalina and Rincon Mountain ranges overlooking Tucson. Six days later we reached Elephant Head summit on a warm, calm and sunny day, but the Santa Rita Mountain range behind us still held large patches of snow. The almost ghostly figure of bare Elephant Head Peak stands out in stark contrast against the base of the dark brown and green Santa Rita Mountains in the Santa Cruz Valley near the southern Arizona border. The Cretaceous-age Elephant Head formed much later than the Triassic-age Mt. Wrightson rocks at the higher elevations of these mountains. Elephant Head Peak, 5, 641' in Mt. Wrightson Wilderness in the northwest Santa Rita Mountains First attempt: bracing against the wind on saddle beneath Elephant Head Peak, 5,641'. On the way to the bottom of Chino Canyon looking at Elephant Head Peak. Hike to saddle on the right following cairns. This hike packs in a wide variety of plants, views and terrain for its relatively short distance and manageable elevation gain. Begin by crossing the stream in Agua Caliente Canyon to walk through knee-high bunch grasses, then pass by the intersection for Little Elephant Head (Peak 5,139'). Catch the first glimpse of Elephant Head Peak on the horizon. Magenta and red fruits of huge Santa Rita prickly pear cacti dot the sides of the trail. Tall rock walls that support an old mining road still stand looking down Chino Canyon. Suddenly, around a corner, an enormous view of the pinkish-tan hulk of Elephant Head Peak overlooks deep Chino Canyon, its rounded rocks and southern cliffs dotted with green shrubs and a few trees. A steep drop with occasional Arizona Rainbow cacti growing in moss brings you to a soothing waterfall. The final ridge climb is the funnest part of the hike, as it requires using old oak tree branches and plenty of rock hand-holds. The rock affords great traction as the ridge drops on both sides for a huge view of all the major ranges to the north, including Baboquivari Peak, the native Tohono O'odham peoples' most sacred place. A close-up to the east of the rugged Santa Rita Mountains provides a beautiful backdrop. One mile into the hike, intersect with mining road built in the early 1900's and an old Santa Rita prickly pear and take a right past sign.
Cairn marking cross-country trail that crosses Chino Canyon to ascend to saddle to the right (southeast) of Elephant Head Peak. Chino Canyon at creek crossing
This elevation is too high and cool for saguaros to grow. This hike travels through the transition between desert grassland and oak grassland biomes of Arizona's Sky Island region. The ocotillo "forests" are remarkable and so are the mature Santa Rita Prickly Pears; they tolerate the cooler winters. Their pads can turn purple during the winter. So many things make this a repeat-hike in the future: solitude, desert wilderness, route-finding, fun Class 2-3 climbing, and views. Plans: Elephant Head Peak plus Little Elephant Head (Peak 5,149').

Yetman Trailhead and Golden Gate Mountain Our Hike It's not every day you can hike through valleys with rocks formally called "Tucson Mountain Chaos" and climb mountains made of compacted ash spewed from a huge volcanic eruption that created a 12-mile wide caldera whose floor collapsed onto an emptied magma chamber. At least this seems to be the current theory of the geologically complex Tucson Mountain Park. Geologists still debate and puzzle over the formation of this area. If you do this hike that I describe here, you will travel on the caldera floor through a beautiful Sonoran desert ecosystem. On this yearly Tucson visit, Fred and I were looking for different peaks in the area to summit. Not that we are tired of peaks in the Santa Catalinas and Rincon Mountains. A winter storm had dumped a lot of snow at elevations above 5,000 feet, so we opted for a warmer experience instead. Tucson Mountain Park is managed by Pima County. Its great website has an interactive map and lists features and activities in this 20,000-acre park that is "one of the largest natural resource areas owned and managed by a local government in the U.S." Outdoor activities range from picnicking to hiking, mountain bike riding and wildlife viewing. On Cat Mountain (a few days after this hike), we were lucky to see five grey Coues whitetail deer, atop steep and rocky rust-colored cliffs. I love celebrating holidays on the trail. There is a certain fellowship that occurs with greetings of "Merry Christmas" or "Happy New Year!" On this Christmas morning, the chill wind stung our faces, but it wasn't long before we felt warmth from the winter sun. The north walls of Golden Gate Mountain, the first summit of our Tucson Mountain Park tour Golden Gate Mountain At the Yetman trailhead, we set out to discover a new area with hike directions from Earthline. At the saddle between Golden Gate Mountain and Bren's Benchmark, 0.4 miles from the trailhead, we oriented ourselves and looked southeast to mountain summits, not yet knowing which ones we would be climbing. We took a right 0.1 miles past the saddle at the cairned trail that gains the Golden Gate through a break between cliffs, and began our climb to Golden Gate Mountain, our highest summit at 4,288 feet (see photo below). The golden color of the rocks perhaps gave this peak its name. Cat Mountain Tuff, a thick layer of consolidated ash, makes up the bulk of these peaks. Tucson Mountain Chaos is the term given by geologists to the rocks that underlie the Cat Mountain Tuff, seen in the valleys. There is no definite answer to the thousands-feet thickness of this Cretaceous-age tuff. Were these rocks below the Cat Mountain Tuff rafted from deeper levels by the rising magma? Or, was this rock caused by a landslide in a caldera that had accumulated the tuff? Of course, when you throw in the geometry of faulting that occurred later when Basin and Range was spreading, it makes the geologist's task of identifying the age relationship of the rocks more difficult. Dodging teddy bear chollas and barrel cactus spines, we marveled at a rare cristate saguaro thrusting up from a steep, south-facing slope under orange cliffs. Theories for the abnormal crest growth range from genetic mutations to lightning strikes. The trail threads between welded tuff towers and tops out, weaves to the left following cairns to the summit. Tucson spreads below, mountain ranges surround on the horizon. Below us, a white cloud moved across the valley and swept over us, briefly covering the peak with fog that created a rare, softly illuminated desert scene. Light rain produced vivid oranges, yellows and greens. Return to Yetman Trail via the same path. Cristate saguaro on left. Bren Benchmark across valley. Scenes from the summit of Golden Gate Mountain, Tucson Mountain Park View of Golden Gate Mountain from Yetman Trail (looking west). Yetman Trail runs through lowest point on saddle to the right. Peak 3,380' on Bobcat Ridge From return to Yetman trail, hike down-valley 1.15 miles to the intersection with the Sarasota Trail. Stay on Yetman to the left (east) for 0.2 miles to arrive at a flat saddle. Bobcat Ridge trail (not marked with signs but obvious) takes off to the right (southwest). The views of Tucson open up as you near the top, Peak 3,380'. It is a relaxed summit with beautiful vegetation, a favorite local hiker destination. From this summit, the steep northern walls of Little Cat Mountain comes into clear view; there's a lot of descending before the climb. To its left (southeast), the dark, enormous hulk that is Cat Mountain will have to be summited another day. Total mileage = 4.3 miles.

Bobcat Ridge Trail leading away from Peak 3,380 toward Little Cat Mountain behind saguaros. Cat Mountain on the left. Little Cat Mountain From Peak 3,380, continue southeast on Bobcat Ridge Trail 0.7 miles to intersection with Explorer Trail; total mileage = 5.0 miles. Turn left (southeast) to climb to saddle in a short distance. At top of saddle, at arrow sign for Explorer Trail, hike up to saddle of Little Cat Mountain to the right (south). Fewer cairns than those of Golden Gate mark this off-trail approach which climbs a quick 400' to the summit, passing a relatively flat grassy area once the trail tops the saddle. From this summit, look to your left; an outrageous view of dark orange and black volcanic Cat Mountain appears as you stand on a cliff overlooking Tucson. The lowering sun and long shadows made this scene even more dramatic. We returned via our ascent to Explorer trail (signs with pink arrow), then made a loop around base of Bobcat Ridge by following Sarasota Trail (signs with maroon arrow), then finally on Yetman Trail to trailhead. Total distance: 9.25 miles. We vowed to climb Cat Mountain, then returned to its summit a few days later with our friend Scott, to celebrate the New Year and plan for hikes together in the beautiful southwestern deserts.
