About this map

The Big Belt Mountains dominate this high-altitude landscape within the Helena National Forest, where steep canyons and broad basins define the local geography. Several prominent natural basins, including Jim Ball Basin, Sunshine Basin, and the namesake Snedaker Basin, suggest a history of seasonal grazing or early backcountry travel. The terrain is marked by dramatic elevation changes, evidenced by Trout Creek Canyon and the unique Hanging Valley in the southwest.

Drainage networks like Rock Creek and Magpie Creek flow through gulches and canyons, carved over millennia. A few primitive routes, such as Antelope Creek Road and Magpie Gulch Road, provide limited access into these remote reaches of Lewis and Clark County. This map documents a largely roadless interior where the boundary between Lewis and Clark, Meagher, and Broadwater counties meets at the high ridges of the Snedaker Divide.
