Ostler Peak is a prominent 12,718-foot summit in Utah’s Uinta Mountains within the High Uintas Wilderness, on land managed by Uinta-Wasatch-Cache National Forest. Ranked as the state’s 37th-highest summit, it rises in especially rugged terrain, climbing more than 1,900 feet above Amethyst Lake in only half a mile. Runoff from the mountain feeds the Ostler and Stillwater forks of the Bear River. Its name was officially adopted in 1932 to honor James Rulon “Dick” Ostler, a Uinta National Forest ranger who worked in the Grandaddy Lake region and died in 1931. The mountain has a subarctic climate, with tundra conditions on its highest slopes.
