Ostler Peak is set within the High Uintas Wilderness on land managed by Uinta-Wasatch-Cache National Forest.

[5] Topographic relief is significant as the summit rises over 1,900 feet (580 meters) above Amethyst Lake in one-half mile.

Precipitation runoff from this mountain drains into the Ostler and Stillwater forks of the Bear River.

The landform's toponym was officially adopted in 1932 by the U.S. Board on Geographic Names to remember the late James Rulon "Dick" Ostler (1900–1931), Uinta National Forest ranger in the Grandaddy Lake region of the Uinta Mountains.

[4][6] Based on the Köppen climate classification, Ostler Peak is located in a subarctic climate zone with cold snowy winters and mild summers.
