1963 Map of Sliderock Ridge

USGS Topo · Published 1975

About this map

The Middle Fork Salmon River carves through the northern reaches of this Idaho wilderness, marking a significant transition between the Boise National Forest and Challis National Forest. The map documents a remote landscape defined by steep drainage systems like Little Loon Creek and Jackass Creek that feed into the river corridor. Settlement and infrastructure are sparse, limited to specialized backcountry outposts such as the Cougar Creek Ranch and the Mahoney Creek Airstrip near the riverbanks. High-elevation vantage points are noted at the Slide Rock Lookout atop Sliderock Ridge, while the Little Creek Guard Station provides a human presence in the dense timber of the southwestern quadrant. This survey reflects the mid-century wilderness management era before the formal designation of large-scale roadless areas.
