Targhee National Forest defines the eastern and southern reaches of this Fremont County landscape, where the high-elevation terrain of the Island Park region meets the open expanses of the Snake River Plain. The topography is dominated by prominent features like Bishop Mtn and the long, sweeping Thurmon Ridge, which separate deep drainages such as Smead Canyon and Bear Canyon. This area functions as a vital transition zone, where timbered slopes descend toward the broad volcanic benchlands of North Antelope Flat and Antelope Flat.
