The Targhee National Forest dominates this volcanic landscape, where the geological remnants of the Henrys Fork Caldera and Island Park Caldera shape the surrounding terrain. High points like Bishop Mtn and Moonshine Mtn overlook a series of broad, open flats such as North Antelope Flat. These plains are essential for local water management, featuring catchments like Sagebrush Spring Reservoir and Wet Weather Reservoir.
