Lemhi Range peaks dominate this high-altitude landscape within the Salmon National Forest, where the complex drainage systems of the Central Idaho mountains converge. The terrain is defined by the significant corridor of Hayden Cr, which is fed by numerous tributaries including Rye Creek, Meadow Cr, and Apple Cr. While largely characterized by its natural features, the presence of Boulder Flat and the Lemhi Valley on the eastern edge indicates areas of relative level ground amidst the steep contours. A network of forest and ranch access routes, such as Tonshier Ranch Rd and Basin Creek Rd, provide the only infrastructure through this part of the range. The map illustrates how human activity is localized to these narrow valleys and historical routes like Old Hwy 28, contrasting with the high basin areas like Hayden Basin.
