Grandjean Peak

Grandjean Peak is a 9,180-foot summit in Idaho’s Sawtooth Range, within the Sawtooth Wilderness and Boise National Forest southwest of Stanley. Known for its rugged profile and dramatic relief, it rises steeply above nearby drainages, including Baron Creek and Goat Creek, and its runoff ultimately reaches the South Fork Payette River. The mountain was named for Emile Grandjean, the first supervisor of Boise National Forest, connecting it to the early administration of the surrounding forest lands. Set in an alpine subarctic climate, it has long, snowy winters, cool to warm summers, and severe winter temperatures, and it remains a prominent part of Idaho’s celebrated mountain landscape.
