About this map

Targhee National Forest dominates this section of eastern Idaho, showcasing a landscape shaped by ancient volcanic activity and modern water management. The topography is defined by the massive Henrys Fork Caldera and the adjacent Island Park Caldera, creating broad basin floors like North Antelope Flat and Antelope Flat. These open stretches are punctuated by prominent volcanic landforms such as Bishop Mtn, Monumental Summit, and the distinctive Little Butte.

Water resources are central to the area's utility, with the Island Park Reservoir reaching into the northern edge and smaller catchments like Sagebrush Spring Reservoir and Wet Weather Reservoir scattered across the flats. Historical land use is evident in the network of specialized routes, including the Lyle Springs Stock Driveway and the Antelope Cutoff, which reflect the region's ranching heritage and the movement of livestock through the high country.
