1957 Map of Gilmore

USGS Topo · Published 1965

About this map

Gilmore sits at the foot of the mountains on the eastern edge of the Lemhi Range, serving as a hub for the region's historic mining activity. High-altitude operations such as the Portland Mine, Latest Out Mine, and Hilltop Mine are scattered across the slopes of Portland Mtn, reflecting an era of intense resource extraction. The presence of the Gilmore & Pittsburgh RR grade illustrates the vital transportation link that once connected these remote camps to broader markets.
