About this map

Flathead National Forest land defines this landscape dominated by the winding fingers of Hungry Horse Reservoir. The topography rises steeply from the water's edge, reaching a high point along the eponymous Pioneer Ridge to the west. This 2017 survey documents the complex shoreline created by the damming of the South Fork Flathead River, revealing several prominent landforms now isolated as islands, such as Clayton Island and Elk Island.

Access to this remote timber and recreation area is largely limited to the W Side Rd and E Side Rd, which skirt the reservoir's banks. Numerous mountain streams, including Canyon Cr and Graves Cr, drain the surrounding slopes into the basin. To the south, Handkerchief Lake and Graves Bay provide specialized focus for local hydrography, showing the intricate relationship between the natural alpine drainage and the managed reservoir system.
