About this map

The Salmon River cuts through the high country of central Idaho, serving as a geographic divide between the Nez Perce National Forest to the north and the Payette National Forest to the south. This 2017 survey highlights the difficult river navigation of this corridor, noting specific hazards such as Dried Meat Rapids, Sheep Creek Rapids, and Bone Creek Rapids. Along the riverbanks, small level areas like Sheep Creek Bar provide rare flat ground amidst steep vertical rises.

Elevations vary significantly across the quadrangle, anchored by Johnson Butte and Marshall Mtn in the south. High-altitude saddles like Johnson Saddle, Canada Saddle, and Beartrap Saddle define the ridgelines that separate drainage basins for Johnson Cr and California Cr. The presence of the Secesh River at the southern boundary further illustrates the complex water network that feeds into the Salmon. Limited access is provided by the Natl Forest Develop Road 318 Rd, which skirts the western edge of these protected lands.
