1966 Map of Homer Youngs Peak

About this map

The Continental Divide forms a dramatic high-altitude boundary on this mid-century survey, separating Beaverhead County, Montana, from Lemhi County, Idaho. High-elevation mining operations are prominent features of this landscape, including the Ajax Mine situated near Ajax Peak and the Ore Cash Mine located further south along the divide. The terrain is characterized by numerous alpine basins containing distinct water bodies such as Slag-a-melt Lakes, Rock Island Lakes, and the Upper Miner Lakes. A network of historic transportation routes, including the Miner Pack Trail and the Hamby Pack Trail, illustrates the rugged logistics required for resource extraction and land management within the Beaverhead National Forest. This mapping effort, field checked in 1966, documents the high peaks of the Bitterroot Range, including Homer Youngs Peak and South Pyramid Peak.
