About this map

Targhee National Forest dominates this high-altitude landscape in Clark County, where the 1987 survey reveals a terrain defined by steep drainage networks and early mineral exploration. The presence of multiple prospects along the western slopes of Heart Mountain and near Myers Creek indicates historical prospecting activity, likely tied to the region's mining heritage. These sites are scattered across the headwaters of Webber Creek and Mc Neary Creek, providing specific coordinates for researchers investigating old claims.

Water sources are vital features in this arid, mountainous environment, ranging from the isolated Antelope Lakes to the flowing Warm Springs Creek at the southern boundary. To the east, the map traces the descent of Deep Creek and the South Fork Deep Creek as they cut through the mountains towards the Snake River Plain. The survey also captures named topographical depressions like Lake Hollow and Robertson Gulch, alongside the deep incisions of Nicholia Canyon and Crooked Creek in the southwest.
