1963 Map of Rock Creek

About this map

Challis National Forest dominates this mid-century survey of the Idaho backcountry, straddling the high-elevation boundary between Lemhi and Custer Counties. The landscape is defined by its hydrothermal activity and narrow access points, featuring multiple Hot Springs and the Owen Cabin located along the deep drainage of Loon Creek. Human activity is concentrated around river travel and backcountry aviation, notably at the Foster Ranch Landing Strip situated along the winding Warm Spring Creek. While largely unpopulated, the area shows early recreational development with established sites like Rock Creek Campground and South Fork Campground. The network of drainages, including South Fork Camas Creek and Kelly Creek, illustrates the complex watershed of this mountainous region before modern road expansion.
