About this map

Upper Red Rock Lake dominates the northern landscape of this 1980s-era survey, set within the Centennial Valley and protected by the Red Rock Lakes National Wildlife Refuge. The map captures a high-altitude wilderness where the Continental Divide winds through the Centennial Mountains, marking the boundary between Montana and Idaho. This intersection of geography and federal management is evident in the sprawling US Sheep Experiment Station and the protected Red Rock Lakes Wilderness.

Resource extraction and land use patterns are visible through several Open Pit Mines and Gravel Pits located south of the wetlands. Recreation is centered at the Upper Lake Campground, while the southern portion of the sheet is defined by the headwaters of the Sheridan Creek drainage system within the Targhee National Forest. The network of 4wd roads and Pack Trails indicates a landscape primarily utilized for scientific research, conservation, and backcountry access.
