From Boulter Peak's summit at 8,300', looking north toward the Oquirrh Mountains.
|
Location: Boulter Peak is this highest point in Utah's East Tintic Mountains, ~ 50 miles SSE of Salt Lake City and on the eastern edge of the Great Basin, in Juab county and on BLM land. We approached it from the major city of Santaquin on I-15.
Overview: enter the historic East Tintic Mountains from Mill Canyon on the west side, traveling though Great Basin sagebrush and possible pronghorn sightings on a two-track rocky road (need high clearance) to the mouth of Mill Canyon, where you park and hike a 4WD road, passing through pretty meadows and aspen forests to arrive near Boulter's summit. At Mill Canyon's saddle, you can either access Peak 8276 summit by its western ridge or continue on through Dry Lake to a steep Boulter Peak approach. The views from Boulter's summit make you realize why this hike is more popular than you may think, in the middle of Utah's eastern Great Basin desert; snow-covered mountain ranges (winter-spring) line the full 360-degree horizon, including the Wasatch front and Mt. Nebo, Timpanogos to the east, and the Oquirrh Mountains to the north, just south of the Great Salt Lake. We ascended forested Peak 8276 by climbing its southern flank to a saddle on its western ridge, and then followed it past prickly pears, junipers, pinyon pines and limestone outcrops with occasional fossils to its summit. Afterwards, visit the Tintic Antique Motorcycle Museum in Eureka to see some cool old rides from back in the day. Distance/Elevation Gain: 8.3 miles/2,600 feet total, climbing both summits. Difficulty: moderate effort on 4WD road to Boulter Peak, navigation off-trail through brush and trees to Peak 8276. Prominence of Boulter Peak: 2,188' Maps and Apps: AllTrails, Boulter Peak 7.5 minute quad, Lists of John Date Hiked: April 5, 2026 Coordinates: Trailhead = , Summit of Boulter Peak = 8,311', Summit of Peak 8276 = 40.01041, -112.20620 Directions to parking/start of hike: from Santaquin, drive east on US 6 West for 22.5 miles, then after the town of Eureka, turn right onto Ajax Avenue, a shortcut to UT 36 N for 0.5 miles, turn right onto UT 36 N. There are two 4 WD choices off of 36 N to take a right: Tintic Mountain Sunset Road or Boulter Springs Road: either will lead you to Mill Canyon Road. We took Tintic Mountain Sunset Rd 8.6 miles from intersection of Ut 36 N and US 6. Boulter Springs Road is the next right, ~ 2,000 feet from Tintic Mountain. We followed Google Map directions (see tab above) which worked perfectly. The coordinates for parking at entrance to Mill Canyon are 40.02713, -112.23084. High clearance vehicle is needed. History: Eureka was a wealthy gold and silver mining district and became one of the wealthiest mining districts in Utah in 1899. "Tintic" is named after a Ute leader. Geology: Fitchville Formation and Pinyon Peak Limestone ~ 350 million years old. We observed corals, bivalves, and bryozoan.

- Mile 3.1 - 3.5: steep climb on 4WD road/scrambling to Boulter Peak summit.
- Mile 3.5 - 4.2: descend Boulter via 4 WD road back down to Dry Lake
- Mile 4.2 - 4.9: ascend southern flank of Peak 8276 to its eastern ridge and then to peak
- Mile 4.9 - 5.65: descend Peak 8276 down its east ridge to Mill Canyon Road.
- Miles 5.65 - 8.25: descend Mill Canyon Road to park at entrance.
Below, two Caltopo Maps show our route in red from parking near Mill Canyon entrance just off of Tintic Mountain Sunset Road, ascending up Mill Canyon to the saddle and Peak 8276 east ridge. We climbed Boulter Peak first, descending down into Dry Lake and then ascending to its summit via 4 WD road.
Next we ascended Peak 8276, taking a short cut through brush, pinyon pines, juniper and rocks to its eastern ridge and then onto its forested and rocky summit. We followed its east ridge down to meet Mill Canyon Road and then hiked down to where we parked at Mill Canyon entrance.

To begin training for an upcoming August Italian/Swiss Alps hiking trek, we summited four peaks this weekend near Provo, Utah. An April snowstorm made us look for peaks at or below 8,000 feet elevation. I called Mountain Works in Provo and spoke to an employee there who recommended Lists of John website for peak searches and summit snow depths. This website was very accurate with snow depth of Boulter and other peaks we hiked this weekend.
I also like to consult Stav Basis' website Stav Is Lost for peaks; this is where I got the idea for Boulter Peak in the East Tintic Mountains.
I love exploring Great Basin mountain ranges, so this sounded inviting, since the Tintic Mountains in central Utah are the very eastern edge of the Great Basin province, with the bulk of its ranges in Nevada. These remote desert peaks, a lot of times on BLM lands, are full of character and beauty, where you can enjoy quiet and become immersed in the land around you.
The East Tintic Mountains did not disappoint in meeting my "character" criteria. Remains of one of the largest Utah silver and gold mining towns are scattered in these peaks and the "icing on the cake" after the hike was checking out Tintic Antique Motorcycle Museum.
We stayed at the Art City Inn in Springville, just south of Provo, where the drive to the trailhead was about one hour or so, traveling west on US 6 west from Santaquin past Eureka, an historic mining town.
There's two 4 WD roads that approach Mill Canyon, where this hike begins. We took Tintic Mountain Sunset Road, 8.6 miles from the intersection of US 6 W and UT 36 N, just after the town of Eureka. The other road is Boulter Springs Road, its entrance a little further north on 36 N.
Sunrise illuminated two pronghorn antelope as we drove across the sagebrush steppe in between the East and West Tintic Mountains. The road was pretty rocky in some places. Juniper became more prevalent as we arrived at the mouth of Mill Canyon, where we found a pull out and parked.
Patches of snow from the recent storm dotted the steep hillsides that lined Mill Canyon. We hiked up this road that had patches of frozen mud that we knew would be wet, slippery mud on the way down.
I don't mind hiking on a road when it goes through beautiful meadows and forests. We saw only one ATV with two guys on the way up, as the grade got steeper.
When you reach the top of Mill Canyon, the road curves to the south as it reaches a saddle, where the landscape opens up to a large dry lake bed and the first view of Boulter Peak. Instead of ascending Peak 8276's east ridge from this saddle, we went on to Boulter Peak first, descending into a basin, and then climbing back up to Boulter's east ridge, at this point walking through snow. A short scramble to the summit over 350 million year old limestone brings you to a grand view and the summit register.
Numerous mountain ranges line the horizon in all directions, with the Wasatch Mountains being the closest and most spectacular. Recent snows had made the top of this range pure white. Boulter's prominence is over 2,000 feet, so its summit feels substantially elevated above other nearby summits and forested valleys.
Four or five inches of snow blanketed the summit, leaving limestone boulders uncovered, so a great place to sit and fill out the peak register. A metal survey marker is on top, with an engraved triangle on it, indicating that this spot is a triangulation station.
Descending Boulter, we looked north to forested Peak 8276 at about the same elevation as where we stood, and saw that we could just walk up its southern flank instead of walking all the way up to its east ridge via the Mill Canyon 4WD road. We aimed for a slight dip on Peak 8276's east ridge.
We walked through intermittent clearings and juniper and pine stands, scrambling over a few limestone outcrops. I saw a few coral fossils. Peak 8276 was mostly limestone outcrops and thick with trees. Snow blanketed the steep north side of the peak, where Mill Canyon Road was somewhere below in that dense forest. We made a delightful trek down the east ridge; delightful because of the big open and grassy terrain bordered with junipers but careful to step over or around the prickly pear cacti.
On Peak 8276 summit, I checked out my Rock'd app and saw that we were standing in the 350 million-year-old Fitchville Formation - this rock created when this part of Utah was on a shallow sea. Walter Fitch, in the late 1890's, had mines and headquarters for his operations in Eureka; this formation may be named after him.
Meeting up with Mill Canyon Road's saddle, we made our way down a very muddy and slippery steep road descent. Morning snow was starting to melt in the meadows. Further down the road, groups of ATVs made rapid ascents, their occupants' faces reflecting the joy of traveling in a beautiful forest. I think some times ATV-ers think we're crazy for walking the trail instead of motoring up it. I prefer walking, but don't have objections to ATV-ers because we are all out enjoying our beautiful outdoors. And that's good for the soul!
On the way back to our hotel, we stopped in the mining ghost town of Eureka at the Tintic Antique Motorcycle Museum. This is a really cool place to sip a mocha or cappuccino as you browse past very antique Harleys, Indians, and even Husqvarna - dirt bikes, roadsters, all sorts of interesting rides!

The Google Earth image below illustrates the pine and juniper-forested Mill Canyon climb with steep terrain on either side. Boulter Peak is not forested, lending itself to incredible views of central Utah including snow-covered Wasatch range and Mt. Timpanogos, close to Provo. Peak 8276, however is a combination of prickly pear-filled meadows and fossils appearing in Fitchville Formation limestone.

A photo of entrance of Mill Canyon Road which requires a high-clearance vehicle. The Great Basin vegetation of Great Basin sagebrush, junipers and native grasses dominate the mouth of Mill Canyon Road. On the approach to find a pull-off to park, Boulter Peak is not in view. We had seen two pronghorn antelope running across this beautiful sagebrush steppe on our way in.

We found a pull-out on Mill Canyon Road close to its opening. Further up, there are a few more openings, but for the most part the road is lined closely by forest. Temperatures were in the mid-30's.

Begin walking on a pinyon and juniper-lined road. The lower parts of this road could be driven by a truck, but further up, the steep terrain requires a jeep, side by sides or other ATV's and motorcycles.
