About this map

Salmon National Forest dominates this landscape, where mining operations and remote settlements mark the high country of Lemhi County. The mapping shows a significant cluster of industrial activity at the Harmony Mine and its associated adit, along with the Pope-Shenon Mine to the north, suggesting the enduring importance of mineral extraction in this part of Idaho. These sites are linked by a network of 4wd trails that navigate the steep drainages of Sevenmile Creek and Tenmile Creek.

Lower elevations are defined by the path of the Lemhi River, where the settlement of Baker and the Salmon SE Base geodetic marker are located. The presence of geothermal features like Salmon Hot Spring and Hot Spring further illustrates the complex geological character of the region. Local landmarks such as Withington and the high peaks of Sal Mountain and K Mountain provide a clear view of the area's geography as it was recorded in the late 1980s.
