The Challis National Forest dominates the northern reaches of this high-elevation landscape, where the jagged ridges of the Pioneer Mountains dictate the flow of numerous drainage systems. The map illustrates a complex network of seasonal watercourses and deep ravines, such as Right Fork Sawmill Canyon and Left Fork Sawmill Canyon, which converge in the northeast. Access to these remote reaches is provided by a handful of established routes, including Sawmill Canyon Rd and the Fish Creek Summit Spur 1 Trl.
