1964 Map of Marshall Peak

USGS Topo · Published 1966

About this map

The Sawtooth Range dominates this mid-1960s survey, marking a high-altitude wilderness where mining interests and forest boundaries intersect. High peaks like Marshall Peak rise above a landscape defined by deep drainages, including the Ross Fork Basin and the headwaters of the South Fork Boise River. The map reveals the area's mineral history through several remote operations, such as the Silver King Mine, Pilgrim Mine, and Ruby Mine, all located near the eastern edges of the quadrangle. Access during this era was limited to a network of trails and a Jeep Trail that navigated the steep terrain between Sawtooth National Forest and Boise National Forest. To the south, Perkins Lake sits near the confluence of Little Perkins Creek and the river, illustrating the isolated glacial hydrology of the Idaho backcountry during this period.
