Gannett Peak stands as the highest summit in Wyoming, with an official elevation of 13,809 ft. The peak is nestled within the Wind River Range, a rugged subrange of the northern Rocky Mountains known for steep granite walls, glacier-fed lakes, and high-elevation passes. Access typically begins from the Switchback Trailhead near Lander, crossing Gannett Glacier, then ascending via a combination of talus slopes, snowfields, and rocky ridges to the summit. The peak commonly involves a multi-day trek that demands glacier travel skills, route-finding, and proper gear for cold, windy conditions. Surrounding the peak are several high-elevation lakes and passes — including Brittle Glacier and Firehole Lakes — making the approach and descent routes highly variable depending on season and glacier conditions.
