Three Prong Ridge and Parachute Ridge define this high-elevation Idaho landscape, where the Red River-Magruder Road snakes along the heights of the Selway Bitterroot Wilderness. This 1995 survey illustrates the intricate boundary between the Nez Perce National Forest and the Bitterroot National Forest, highlighting a region shaped by complex drainage systems like Warm Springs Creek and Running Creek. Deep in the interior, the map reveals isolated landmarks such as Lynx Meadows and the sheer descent known as The Drop-off, providing essential data for those studying the land management history of the Frank Church-River of No Return Wilderness. The topography around Three Prong Mountain remains largely untracked, save for the ridge-top roads and forest service administrative lines.
