Poison Peak and Watson Peak anchor the southern reaches of this high-altitude terrain within the Salmon National Forest. The landscape is defined by the sharp relief of the Lemhi Range, where drainage systems like Copper Creek and Warm Spring Creek carve through several prominent basins, including First Basin and the North Basin. This area serves as a critical headwater region, marked by seasonal water sources such as Porcupine Spring and the Bull Summit Waterhole.
