Eocene Peak is a granitic summit with an elevation of 11,569 feet (3,526 m) located on the crest of the Sierra Nevada mountain range, in northern California, United States.

Topographic relief is significant as the summit rises nearly 2,000 feet (610 meters) above Piute Creek in one mile.

[5] Most weather fronts originate in the Pacific Ocean, and travel east toward the Sierra Nevada mountains.

As fronts approach, they are forced upward by the peaks (orographic lift), causing moisture in the form of rain or snowfall to drop onto the range.

Precipitation runoff from this landform drains north into Blacksmith Creek which is part of the Walker River drainage basin, and south into Piute Creek which is a tributary of the Tuolumne River.
