Mount Mellenthin is the second highest point in the La Sal mountain range which is located in San Juan County. The La Sals are the second highest mountain range in Utah, second only to the Uinta Mountains.

The La Sals are laccoliths. Magma rose under sedimentary layers, intruding into sandstone and shale layers, but did not break the surface as in a volcanic eruption. Successive intrusions developed overlapping laccolithic blisters. The intrusions lifted the overlying sediments as much as 6,000'.

Getting There

Moab ~ La Sal Pass
From Moab, UT drive 21.8 miles south on Utah highway 191 to the junction of Utah Highway 46 at La Sal Junction. Turn east (left) onto Utah 46, pass through the small town of La Sal, and drive 12.8 miles to the signed, gravel road stating, "La Sal Pass." Turn left onto this graded gravel road. Drive 2 miles and turn left (west) onto the La Sal Pass Road at a marked junction. Drive another 7.4 miles to La Sal Pass at 10,125 feet. Most 2WD vehictes will make it to this point, however, in late spring there is a creek crossing that may present a challenge during high run-off periods. There are a couple of possible starting points for Mt. Peale. One is to drive all the way to La Sal Pass near Medicine Lake and park. The other, is to park at the drainage just past the turnoff to Beaver Lake. Both options are viable and the difference in distance is negligable. Alternatively, La Sal Pass can be approached from the west side, but 4WD and high clearance is required. (copied from the Peale Page, I found the Peale description to be accurate)
The turn off after Beaver Lake is approximaety .50 of a mile before the La Sal Pass trailhead and would the the last right hand turn within that distance.

Red Tape

Mount Mellenthin is in the Manti-La Sal National Forest. No permits or summit fees are necessary.


Since Mount Mellenthin is in the Manti-La Sal National Forest camping is plentiful along the La Sal Loop road for its entirety.

La Sal Pass:
Take the forest road leading south from the trailhead.

Medince Lake:
Take the last left hand turn (1000 meters) before La Sal Pass

Peale trailhead area:
Take the Right hand turn (.50 mile) before La Sal Pass



Children refers to the set of objects that logically fall under a given object. For example, the Aconcagua mountain page is a child of the 'Aconcagua Group' and the 'Seven Summits.' The Aconcagua mountain itself has many routes, photos, and trip reports as children.



Parents refers to a larger category under which an object falls. For example, theAconcagua mountain page has the 'Aconcagua Group' and the 'Seven Summits' asparents and is a parent itself to many routes, photos, and Trip Reports.
