The Colorado River Aqueduct carves a path through the southeastern corner of this arid landscape, a critical piece of water infrastructure cutting across the Mojave Desert. To the north, the sharp elevations of the Mopah Range dominate the topography, culminating at Negro Peak. This 2015 survey illustrates the isolation of the Vidal Valley, where the terrain is defined by dry drainage features like Vidal Wash. The intersection of modern engineering and a harsh natural environment is evident as the aqueduct traverses the basin, following a route largely parallel to the distant transportation corridors of Route 62 and Route 95. The map provides a clear record of the public land survey system grid, showing the township and range boundaries that organize this part of San Bernardino County.
