The Little Thompson River and its North Fork wind through the mountain valleys of the Roosevelt National Forest, defining the rugged geography of this 2013 survey. The landscape is marked by a legacy of water engineering and ranching, evidenced by the presence of the Pole Hill Tunnel, Rattlesnake Tunnel, and Bald Mountain Tunnel which cut through the granite peaks. These subterranean structures connect the high-altitude hydrology with local basins like Pinewood Lake and South Side Reservoir.
