About this map

The high backcountry of Challis National Forest is defined here by a network of drainage systems and high alpine water bodies, including Horseshoe Lake and Fish Lake. The area reflects a mid-century landscape accessible primarily by primitive routes, with the Winnemucca Pack Trail and various other pack trails serving as the primary infrastructure for movement through the steep terrain.

Mineral exploration is evidenced by scattered prospects located near the headwaters of the West Fork Yankee Fork. The geographic center of the sheet is dominated by the Knapp Lakes group, situated below the heights of Cabin Creek Peak. This 1964 survey captures a moment before modern wilderness designations further restricted access, showing the relationship between early mining interests and the natural watershed of Beaver Creek and Loon Creek.
