Johnston Peak is named for A.J. Johnston who had several mines on the ridges of Johnston Peak and a cabin on the confluence of Hyndman and Johnston Creeks in the East Fork Basin of the Wood River. A climb to the summit of Johnston Peak will involve approximately 3,800 feet of elevation gain, depending on what trailhead is chosen with a summit just shy of 10,000 feet. Spectacular views of the Pioneer, Boulder, and the Smoky Mountains will be the reward from the summit. The shortest distance to the summit is via Uncle Johns Gulch however this route is mostly trail-less. Mountain Bikes are only allowed on the lower trail of Uncle Johns Gulch. Ski descends are steep and highly susceptible to avalanches. Johnston Peak was skied in 1939 by Andy Henig.
