Tanque Verde Peak,  7,047' -  Saguaro Wilderness, Rincon Mountains

6/30/2019

3 Comments

 
On this exceptional 18-mile round-trip hike, experience remarkable biological diversity beginning in the saguaros and desert scrub, ending in the evergreen oaks and alligator juniper of the pine-oak woodlands.  The reward is an immense view of mountain ranges in southern Arizona.

If I had to pick only one word that best describes the essence of the hike to Tanque Verde Peak in the Saguaro Wilderness, I would choose "diversity".  This nine-mile portion of the Tanque Verde Ridge Trail that begins at the Javelina trailhead in Saguaro National Park east of Tucson and ends 4,000 feet higher at Tanque Verde's summit treks through four biotic communities, each containing its characteristic plant and animal species.  These "life zones" -Sonoran desertscrub, semi-desert grassland, Madrean evergreen woodland, and temperate forest overlap, so that prickly pear cactus grows alongside bunch grasses in transition zones. 

An evening of April thunderstorms and light rain the previous night had created a chill and freshness to the morning air.  Fred and I had hiked this trail 6.9 miles to Juniper Basin the year before.  This year, we were determined to hike the full nine miles to the peak.

The trail, initially hard and rocky, winds through stately saguaros, barrel cactus and prickly pear cacti filled to the brim with new flower buds (in April), straightens and gains elevation through tall bunchgrasses, bear grass, and finally oak trees.  Leaving the desert scrub behind, the trail rises and falls through an ever-increasing amount of oaks.  It goes through lovely Juniper Flat,  through the cool shade of Ponderosa and Pinyon pines along with Alligator juniper toward the summit of Tanque Verde Peak where the tread is soft with accumulated pine needles.   Grasping the rough and weathered granite on the last few feet of the summit block, you hoist yourself up a huge boulder to see the dark, immense summit of Rincon Mountain on the south ridge and the breathtaking view of southern Arizona's mountain ranges.

The only bad part is the sore feet after this 18-mile hike; however, a small price to pay for this unique experience.

Tanque Verde, or "green tank" refers to the green algae present in a large tank of water used for stock in the 1800's.  It is now the name given to the valley east of Tucson that is bordered by the Santa Catalina Mountains to the north and the Rincon Mountains to the east.  The Pima Indians lived there in the 1600's, and Tanque Verde Ranch was established in the 1800's.

Sonoran Desertscrub  (a.k.a. Thornscrub)
This hike begins at the Javelina picnic area in East Saguaro National Park - elevation 3,100 feet, in the creosote-scented Sonoran desertscrub biome.  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.  Thorny saguaros dominate this community, along with cacti of various forms, such as the flower bud-studded prickly pear. Bright colors of wildflowers in spring line the path:  coral/red claret cup flowers of the hedgehog cactus, yellow prickly pear flowers, pink fairyduster, bright orange ocotillo, and peach-colored globemallow flowers.  Mesquite and Palo Verde trees are present in the Sonoran desertscrub biome which is intermediate between the desert and tropical forest biomes.   The cheerful yellow flowers of Encelia farinosa, or brittlebush add bursts of color among the red-brown rocks and green cacti.

After the trail register, the trail begins to climb, with sweeping views of Tucson basin.  Before emerging out of the desertscrub biome into grassland, at about two miles, the trail provides unobstructed views of the mountain ranges west and south of Tucson.  From here, the trail stays on the wide ridge, rounding hills at some intervals, or heading straight up and then down, causing mild losses in elevation.  It gains 700 feet in the 1.4 miles after the trail register.  Just after 4,000 feet elevation, saguaros become more scarce, and grass more prominent, as it transitions into semi-desert grassland ecosystem.

According to a reader of this post:  "Holes are made from Gila Woodpeckers and Gilded Flickers and other birds and animals use the nest holes when the woodpeckers leave."
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.  Tanque Verde Peak is still six miles away and not visible.  The manzanita and oak species are prevalent in the oak savannah community as the trail ascends, transitioning into pine/oak woodland.

Madrean Evergreen/Pine/Oak Woodland
​At about four miles, at mid-elevation that is between the desertscrub and the temperate forest biomes, the trail ascends and descends through ever-increasing oaks.  At 5.9 miles, the trail drops to make its long entrance into Juniper Basin Campground, crossing beautiful Box Canyon with rock cairns to guide you through stretches of rock floors.  At 5,940 feet elevation, Juniper Basin Campground is an airy and spacious place with towering Pinyon pines and oaks and my favorite - the alligator juniper with its scaly square-patterned bark.  There's an outhouse and food box for overnight campers.

Evergreen oaks such as 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.  Understory perennial grasses rustle, adding to the peace of this place.

The elevation gain to Juniper Basin Campground is 2,840 feet in 6.9 miles.  Tanque Verde Peak is another 2.1 miles and 1,100 feet in gain.  Such a long, arduous adventure; it's tempting to turn back and call it good, but the additional effort to get to the summit is worth it.  We summon our motivation and resume our quest not knowing at this time how we would quickly forget our tired legs once on Tanque Verde summit, and how the forest and view would exceed our expectations.

Signs indicate the trail continues northeastward from Juniper Basin.  Finally, Tanque Verde Peak comes into view, but seems far away.  Orange blazes on trees occasionally mark the trail, easy to follow.

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.

We catch glimpses of Tanque Verde Peak as we climb on a well-traveled path through the shade, scent and rough texture of this forest.   Emerging out of the dense forest into an open wide ridge, Tanque Verde's many columnar rocks and crevices comes into sharp view at about 6,500 feet.  The trail weaves around large boulders and manzanita:  the metal summit sign is seen to the east at about 8.7 miles.  Reach an old signed intersection that points the way to Cow Head Saddle which is  another 2.5 miles on the ridge; continue straight ahead to Tanque Verde.  Somehow I forget my tired legs when we reach the summit, where the spectacular scene doesn't reveal itself until you scale a looming boulder that stands in your way, a short climb that feels like the final test for this summit conquer.

​100 yards from the summit!
The view is spectacular.  It takes a few seconds to fully comprehend how high this peak rises above the surrounding desert floor and the layers of mountain ranges visible.  Mexico is to the south,  the Santa Rita and Galiuro Mountain ranges to the southeast.  The Santa Catalina Mountains thrust up rocky prominences to the northwest.  Rincon Peak is just across the valley to the east, its massive hulk in the shadow of clouds.

We relish the view and accomplishment and the wonder and beauty that the Sonoran desert brings.  The wind is brisk and cool, but by the time we get down to the desertscrub and walk through the saguaro stands, seven miles away, it will be warmer, even with the sun setting.  There are about four or five hills to climb on the long walk out, scaled with a bit more determination than on the way in.   Glad we are getting back at sunset, for above the golden Tanque Verde Ridge slowly becoming covered by shadows, a nearly full moon is rising.

    A  trip to Jumbo Rocks Campground in Joshua Tree National Monument 38 years ago sparked my passion for hiking, exploring, and learning about desert ecosystems.  For the past 25 years, my husband Fred and I have explored the American West together; we love this land and I hope to inspire you to get out and explore through my photographs and trip descriptions.
    In 1992, Ray Wilson and I conceived the first Cactus to Clouds hike which climbs over 10,000 feet in one day to the summit of Mt. San Jacinto near Palm Springs, California.
