1957 Map of Gilmore

USGS Topo · Published 1958

About this map

The Latest Out Mine and Mountain Boy Mine represent the industrial core of the Lemhi Range during the mid-1950s, marking a landscape defined by significant high-altitude mineral extraction. Located near the settlement of Gilmore, these workings are clustered among steep peaks such as Portland Mtn and Nigger Peak, connected to the valley floor by a dedicated mining Grade. This survey illustrates the convergence of three major public lands—the Salmon National Forest, Challis National Forest, and Targhee National Forest—across the rugged Lemhi and Custer county line.
