1957 Map of Cartwright Canyon

About this map

Boise National Forest dominates the rugged southern landscape of this 1957 survey, where high ridges and deep drainages define the transition toward the Boise Basin. The terrain is marked by distinctive geological features like Bread Loaf Rock and Stack Rock, which served as essential landmarks for travelers and early ranchers. The Dobson Ranch represents the rural settlement patterns of the era, situated near the confluence of major seasonal drainages such as Shafer Creek and Harris Creek. This mapping reflects a period of transition, where the historic Horseshoe Bend Road and various unnamed jeep trails provided the primary access for logging, grazing, and early recreation. The presence of Home Lake in the north and the winding course of Spring Valley Creek demonstrate the vital role of water management in this high-country environment.
