Targhee National Forest and Gallatin National Forest dominate this high-country terrain along the border of Idaho and Montana. The landscape is defined by its complex hydrology and dramatic geology, specifically the northern reaches of the Island Park Caldera. High-elevation flats like Chick Cr Flat are interspersed between steep drainages such as Black Canyon and Trail Canyon.
