1956 Map of Goldstone Mtn

About this map

Continental Divide crests along the high ridges of the Beaverhead Mountains in the mid-1950s, defining the border between Idaho and Montana. This high-altitude landscape is marked by remote mining operations, including the Goldstone Mine and Jahnke Mine, which were established near high alpine lakes like Jahnke Lake and Swift Lake. The map reveals the infrastructure of early resource extraction and irrigation, noting several prospects, Tunnels, and a Siphon and Flume near the Lemhi River. In the valley, the Sandy Creek School serves the rural population near the small settlement of Baker, where the Overland Trail and a Jeep Trail trace the early transportation routes through the Lemhi Valley. The terrain shifts from the high peaks of Center Mtn and Goldstone Mtn down to the meadows of the Salmon National Forest and Beaverhead National Forest.
