1956 Map of Goldstone Mtn

About this map

The Lemhi Valley and the high ridge of the Continental Divide define this landscape along the border of Idaho and Montana. Near the settlement of Baker, the Lemhi River flows through a developed corridor of ranching and early infrastructure, including the Sandy Creek School. The topography transitions sharply from the valley floor to the high peaks of the Beaverhead Mountains and the Salmon River Mountains, where human activity is marked by remote mining operations such as the Goldstone Mine and Jahnke Mine. Geothermal features like Sharkey Hot Spring reflect the region's diverse geology. This survey captures a moment when high-altitude access was maintained primarily through a Jeep Trail crossing Goldstone Pass, providing a detailed look at the intersection of high-country resource extraction and valley settlement in the mid-1950s.
