About this map

The Big Lost River carves a path through the northeastern corner of this high-altitude landscape, flanked by the prominent White Knob Mts and protected within the Challis National Forest. The map documents a rugged drainage system where numerous tributaries, including Twin Bridges Creek, Wildcat Canyon, and Harry Canyon, feed into the river's basin.

Evidence of mid-century infrastructure is found in the Twin Bridges Landing Strip Road and a remote Radio Facility, indicating the area's importance for aviation or communications despite its lack of permanent towns. The presence of a Gaging Station and several Wells near Baptlett Road underscores the critical management of water resources in this part of Custer County during the late 1960s. A network of Jeep Trails provides the primary access to the backcountry forks of the river, such as the Wildhorse Fork and East Fork.
