2017 Map of Thompson Creek

About this map

The Salmon River flows through the southern reaches of this Custer County landscape, providing a low-elevation corridor for the small settlement of Torreys. This mountain terrain is largely defined by the Challis National Forest, where a dense network of drainages such as Thompson Creek and Mill Creek carve into the high country. The map documents a rugged interior accessible via Thompson Creek Rd, which tracks the primary waterway northward into a region marked by numerous gulches and canyons. Distinctive local landmarks like Oster Gulch and Peach-Cinnabar suggest the historical importance of prospecting and drainage systems in this part of central Idaho. The proximity of the river to these steep slopes reflects the classic intersection of high-mountain hydrology and the early transportation routes that followed the water's edge.
