1966 Map of Big Hole Pass

USGS Topo · Published 1970

About this map

The Continental Divide defines the spine of this mid-1960s survey, marking the boundary between the Salmon National Forest in Idaho and the Beaverhead National Forest in Montana. The landscape is dominated by high-altitude drainages and peaks, notably Morgan Mtn, where numerous unnamed prospects suggest a history of mineral exploration. Remote alpine waters like Morgan Jones Lake feed into a network of steep canyons, including Thompson Gulch and Dahlonega Creek.
