About this map

Three Prong Mtn and the surrounding Nez Perce National Forest define a landscape of high ridges and deep drainage systems within the Selway-Bitterroot Wilderness. This terrain is structured by prominent divides such as Patrol Ridge, Grouse Ridge, and Parachute Ridge, which separate the watersheds of Running Creek and Bargamin Creek.

A network of backcountry routes, including the Patrol Ridge Trail and Grouse Ridge Trail, provides access to landmarks like Eagle Point and Lynx Meadows. Notable for its physical geography, the map identifies specific riverine features like Warm Springs Bar and the dramatic topography of The Drop-off. The arrangement of these trails and named camps reflects the management of one of the nation's most protected primitive areas during the late twentieth century.
