Mount Untermann is a shapely 12,000 foot peak in the Uinta Mountains. In contrast to most other peaks in the area, this one has an official name. The peak has some steep sides on the east, northwest and northeast faces, but the west slopes and south ridge are very gentle.

Mount Untermann is one of the easiest 12,000+ foot mountains in the Uintas, but is seldom climbed and is a good place for solitude. It lies in a vast sea of peaks and tundra and is surrounded by beautiful lakes and meadows.

Most of the trails in this eastern section of the Uintas are not used much, and many are fading away because of very light or no foot traffic. Even though the peaks are easy to climb, and not very rugged, this is a good place to go come to if you enjoy solitude. Many trails are shown on the topo maps, but many of them don't exist anymore.

As mentioned, Mount Untermann is not overall a rugged peak, although it has some steep sides, but it is very seldom climbed, and there is no register on the summit. The peak is still easy to climb, and can be easily done in a day, in contrast to most of the 12,000+ foot peaks in the Uintas. Like all peaks in the Uintas, except for Bald Mountain, Mount Untermann has no trail to the summit.

The Uinta Mountains are one of the few mountain ranges in North America that run east to west rather than north to south. Within the Uinta Mountains are about 2000 lakes, and some 900-1000 are full of trout. Along with the San Juans in Colorado, the Uintas have more contiguous area above timberline than any other area in the Continental United States. This is a beautiful area with many lakes, meadows, wildflowers, and some rugged peaks. Solitude is usually easy to come by once you leave the popular fishing holes behind.

The Uinta Mountains are very rugged in the northeast section. Beginning at Hayden Peak and east to Mount Lovenia, the Uintas are not unlike the Tetons or other ranges. East of Lovenia, the peaks are more gentle, with a few rugged peaks (ie Red Castle and Henrys Fork Peak) scattered about until you are as far east as the Henrys Fork/Kings Peak area. East of Kings Peak, the Uintas become very gentle and the peaks are very rounded with only a few scattered cliffs about.

Getting There

Mount Untermann can be climbed from many directions. One is from the west and Paradise Park, one is from the east and from near Ashley Twin Lakes, one is from the Highline Trail near Hacking Lake and one is from Chepeta Lake. These are the accesses that will be discussed on this page. Other access routes are from the north and Browne Lake, but I haven’t access the surrounding peaks from there.

The route from the Highline Trail from Hacking Lake is the shortest and the road is good for all vehicles. The other routes are attractive too, depending on which other peaks you wish to climb in the area.

Highline Trail/Hacking Lake Trailhead

From near the center of Vernal along Highway 40, turn north at the sign for Maeser and follow the road north to 500 North. Turn west here and follow 500 North to 3500 West. Turn north here. There is a sign for Red Cloud Loop Road. Follow the Red Cloud Loop Road through Dry Canyon. If you have time, make sure to stop at the pictographs and petroglyphs along the way.

The road becomes a good gravel road at the Forest Service boundary. Follow the Red Cloud Loop all the way to a major junction with the road to Hacking Lake. A sign points the way to Hacking Lake, and follow the road to near Hacking Lake. Instead of turning left at the lake, follow the main road right and to its end. This is the trailhead.

Ashley Twin Lakes Trailhead

From near the center of Vernal along Highway 40, turn north at the sign for Maeser and follow the road north to 500 North. Turn west here and follow 500 North to 3500 West. Turn north here. There is a sign for Red Cloud Loop Road. Follow the Red Cloud Loop Road through Dry Canyon. If you have time, make sure to stop at the pictographs and petroglyphs along the way.

The road becomes a good gravel road at the Forest Service boundary. Follow the Red Cloud Loop all the way to a junction with the road to Ashley Twin Lakes. A sign points the way to Ashley Twin Lakes, but be aware of missing signs as they tend to disappear. Follow the road towards Ashley Twin Lakes. It quickly becomes a 4wd road.

Ignore the side tracks and stay on the main track until you reach the end of the rough road. Cars will have to be parked earlier.

Park here. This is the trailhead.

Paradise Park Trailhead

Make sure to have a good map before driving to the trailhead. This is how we found the road in 1994, but things do change because this is an active logging area.

From Roosevelt on Highway 40, drive east along Highway 40 to 8500 East near Fort Duchene. Turn north on 8500 East. The road curves around to the east and becomes 9600 East and heads north to 7000 North. Turn right on 7000 North and drive east to the tiny town of Lapoint.

From Lapoint, drive north on FR (Forest Road) 104. Follow FR 104 to just short of the turn-off to Paradise Park Reservoir. Notice the road going past Mill Pond on the map. This is your road. Drive the 4wd road past Mill Pond and continue north. Continue along the rough road to a sign and 4-way junction. Park here.

If you don’t have a 4wd, you can park at Paradise Park Reservoir and hike to the 4-way junction, but the trail can be hard to find among the old logging roads. Make sure to have and use a good map.

Routes Overview

As mentioned, Mount Untermann can be climbed from many directions. None of these trails and routes are used very much, so expect solitude as well as some route finding. Some of the many possibilities are mentioned below:

Via Hacking Lake and Highline Trail

The route up Mount Untermann from the Highline Trailhead/Hacking Lake is but one (and perhaps the shortest and easiest) of the many routes that could be used to climb Mount Untermann. Because it is the route I used climbed the peak, it will be the route with a route page.

As peak climbs go, it’s a pretty gentle route and since the trailhead is at a relatively high elevation, it is a fairly mellow climb. The climb is above timberline for most of the way, so you have to keep a close eye on the weather.

See the route page for more details.

Ashley Twin Lakes and Lakeshore Basin

This route from the southeast is only a little longer and probably about as easy as the route from the Highline Trail/Hacking Lake. The road is much rougher than the road to the Highline Trail though.

The Lakeshore Basin is a beautiful area filled with lakes and meadows. The routes up Mount Untermann join the routes from the Highline Trail at the vicinity of Lake Wilde.

This route can also be completed in a long day trip.

Paradise Park

There are two major variations to the area from Paradise Park, which is a southern route.

One trail heads north from Paradise Park through Blanchett Park, Lightning Park, and Deadman Lake. From Deadman Lake, the Highline Trail heads east to Gabbro Pass which is on the standard route of Mount Untermann (see the route page for the Highline Trailhead).

A second trail heads northeast from Paradise Park and past Red Belly Lake and over the area of Lakeshore Peak to Gabbro Pass. It is likely that the trail from Red Belly Lake to Gabbro Pass is indistinct and I didn’t see any signs of the northern portion of the trail while climbing Lakeshore Peak.

Most people will want two days for these routes, or perhaps more if you are climbing several peaks in the area.

Chepeta Lake/Highline Trail

The Highline Trail also heads east from Chepeta Lake and goes over Gabbro Pass just to the south of Mount Untermann. This is longer than the eastern approach of the Highline Trail from Hacking Lake, but passes some beautiful lakes and gives you an opportunity to climb several more peaks along the way.

Plan on two days minimum, especially if you want to climb several peaks in the area.

Northern Routes

Maps show two trails approaching the area from Browne Lake. I have not approached these peaks from that direction, but am guessing that the trails are indistinct since I haven’t seen any sign of them where they join the trails and routes mentioned above that I have been on.

If you have a good map and several days at your disposal, this could make an interesting loop hike that climbs several peaks along the way.

Red Tape

No permits are required. Normal wilderness rules apply.


Car Camping

If you like camping with not many restrictions, and without the crowds, this is a good place to come.

The road to the Highline Trail and Hacking Lake has many good campsites, including at the trailhead.

Dry Fork, on the road to the Ashley Twin Lakes Trailhead has many nice campsites in the forest, some with picnic tables and fire places. All are free of charge! There are other campsites closer to the trailhead along the road, including near the trailhead.

The road to the Paradise Park trailhead has many nice campsites as well. Paradise Park is the only official campground in the area.

The roads to Chepeta Lake have many good campsites as well.

Backcountry Campsites

There are many backcountry campsites along all routes.

The route from Hacking Lake and the Highline Trail is above timberline for most of the route though, so it’s best to drop down into the Lakeshore Basin to camp.

The route from Ashley Twin Lake has many good campsites in the Lakeshore Basin.

The Paradise Park Route has many good campsites with water including Corral Park, Macks Park, and Fish Lake. Good campsites are around Hooper Lakes near the Ashley Twin Lakes Trailhead.

The route from Chepeta Lake has good campsites around Deadman Lake, and although not crowded is the most popular backcountry destination around here. It would make a fine base for climbing many peaks in this area.

When to Climb

Mid-July through Mid-September is the normal hiking season. The roads in the area are usually open in late June or early July. They usually close when ever the first big snowstorm of the season hits, usually between mid-September and mid-October.

While it is true that Mount Untermann is a long one day climb in summer, by Uinta standards, it is a short climb. This is not true in winter. None of the roads in the area are open in winter. I don't know if the mountain has ever been climbed in winter.
