1966 Map of Twin Butte

About this map

Nez Perce National Forest land defines this portion of the Idaho backcountry, where the high-altitude terrain is carved by a network of drainage systems. The northern reaches are dominated by the heights of Pettibone Ridge, falling away toward Pettibone Creek and Squad Creek. This mid-1960s survey illustrates a landscape managed for conservation and limited access, with the southern half protected as part of the Selway-Bitterroot Wilderness. Transport is restricted to the established Pack Trail system, which winds along the high contours of Elk Ridge and Long Ridge. Water sources such as Bear Creek, Paradise Creek, and Cub Creek flow through deep-cut valleys beneath the prominent summit of Twin Butte. The map reflects a period of modern wilderness designation, recording the specific boundaries and topographical detail of these protected Idaho mountain ranges.
