1972 Map of Bighorn Canyon

About this map

Johnson Valley defines the northern half of this desert landscape, characterized by a grid of namesake roads such as Joshua Tree Avenue, Datura Avenue, and Saddlerock Avenue. The map captures the area's transition from high-desert plateaus to the prominent Bighorn Mountains, where drainage patterns like Bighorn Canyon and Ruby Canyon cut deep into the terrain. Human presence in this arid region is marked by utilitarian infrastructure, including a Landing Strip and a secondary Landing Field, along with scattered resources like a Water Tank, several Cistern points, and the Rock Corral. At the southern edge, the Parsons Ranch and Well locations indicate the small-scale agricultural and ranching efforts that sought to utilize the sparse water supply in this corner of San Bernardino County.
