1957 Map of Cartwright Canyon

About this map

Boise National Forest dominates the southeastern terrain of this Idaho landscape, where the high ridges of the Boise and Ada County line meet. The 1957 field survey captures a region defined by its drainage basins and early ranching, centered on Cartwright Canyon and the winding Shafer Creek. Landowners and researchers can trace the historic route of the Horseshoe Bend Road as it cuts through the northwest corner near Home Lake, while specialized local landmarks like Bread Loaf Rock and Stack Rock provide distinct orientation points for those navigating the high country. Isolated outposts such as Dobson Ranch reflect the mid-century settlement pattern in these drainage valleys, linked by an extensive network of Jeep Trails that traverse the divides between Harris Creek and Spring Valley Creek.
