1967 Map of Rock Roll Canyon

USGS Topo · Published 1971

About this map

The Boulder Mountains dominate this high-elevation interior where the Sawtooth National Forest meets the Challis National Forest at the Blaine and Custer County line. This 1967 field-checked survey documents a landscape defined by sharp drainage divides and alpine basins, with the Big Wood River and its East Fork North Fork feeding the headwaters in the northwestern corner. Evidence of early land use is found in scattered Prospects and a Mine near the center of the sheet, while the presence of Sawmill Gulch and Taylor Canyon suggests historical timber or livestock activity. The topographic detail captures the steep transition from the narrow floor of Rock Roll Canyon up to the high peaks, providing a precise record of the trail networks that connected these remote basins before more modern infrastructure arrived.
