About this map

Salmon River drainage systems define this section of the Challis National Forest in central Idaho. The settlement of Torreys sits at the southern edge of the sheet along the river, serving as a primary point of human activity amidst a dense network of mountain tributaries. The terrain is characterized by steep elevation changes, with major drainages like Thompson Cr, Basin Cr, and Slate Cr carving deep paths through the forest landscape.

Infrastructure is concentrated along the river corridor and major canyon floors, primarily via Thompson Creek Rd and Robinson Bar Rd. This modern survey illustrates how transportation follows the natural contours of the land, providing access to remote features like Oster Gulch and Cherry Cr. The map preserves the complex nomenclature of the region's hydrography, from Peach-Cinnabar in the north to Mill Cr in the south, reflecting a legacy of resource exploration and wilderness management.
