2017 Map of Thompson Peak

About this map

Irwin sits at the southwestern edge of this landscape, serving as a gateway to the high-elevation wilderness within the Targhee National Forest. The topography is defined by a dense network of drainages and peaks, including Thompson Peak and Atkinson Peak, which rise above a series of deeply carved canyons such as Dead Man Canyon and Little Bear Canyon. The drainage patterns suggest a high-alpine environment where seasonal runoff feeds into Rainey Cr and the complex Palisades Cr system.
