About this map

Loon Creek winds through the heart of the Challis National Forest, serving as the primary drainage for this high-elevation backcountry in Custer County. In the early 1960s, the area supported a mix of wilderness infrastructure and isolated private holdings, including the Boyle Ranch and its adjacent Boyle Landing Strip. The presence of a Prospect near Mayfield Creek suggests the enduring interest in the region's mineral potential, even as recreation became more formal with the establishment of the Transfer Campground and Tincup Campground.
