Darwin Peak is an 11,647-foot mountain in western Wyoming’s Gros Ventre Range, within the Gros Ventre Wilderness and Bridger-Teton National Forest. The range’s third-highest summit, it rises steeply above the Gros Ventre River and drains into that river’s headwaters. By the early 20th century it had become important in regional surveying, with a USGS benchmark placed there in 1905 and the peak used as a triangulation station by at least 1914. Its officially adopted name honors early homesteader Fred Dickerson Dorwin, not Charles Darwin. Owing to its high elevation, the mountain has an alpine subarctic climate with snowy winters, cool to warm summers, and year-round precipitation.
