About this map

The Raft River Valley landscape in 1958 is defined by its network of high-altitude springs and canyons descending from the Sublett Range. Within the Sawtooth National Forest, the map reveals a rugged terrain where water sources such as Lower Heglar Spring, Bruce Young Spring, and Quaking Aspen Spring were critical waypoints. Significant elevation is marked by North Chapin Mountain and Eagle Point, providing a glimpse into the topographical challenges of southern Idaho's high desert.

A pipeline and numerous jeep trails cut across the valley floor, highlighting the infrastructure supporting local agriculture and ranching, most notably at the Broken Circle Ranch. The map also captures the complex drainage systems of Heglar Canyon and Fall Creek, which transition from narrow mountain gorges into the wider valley basin. This era shows a balance between federal forest preservation and private ranching interests at the intersection of Cassia, Power, and Oneida counties.
