About this map

Johnson Valley occupies the northern expanse of this High Desert landscape, where the flat valley floor meets the rising elevations of the Bighorn Mountains and San Bernardino Mountains. The transition from the arid Mojave Desert into the more complex topography of Bighorn Canyon is marked by a network of rural roads such as Joshua Tree Rd and Quailbush Rd.

Remote infrastructure like the Valley Vista Airport and natural water sources such as Saddlerock Spring reflect the region's sparse but deliberate settlement patterns. The map also captures specialized drainage features like Rubber Drain Two, illustrating how land management and road networks, including Rock Corral Rd, navigate the alluvial fans and high-altitude terrain that define this part of San Bernardino County.
