Lucy Gray Mountains dominate the eastern topography of this desert landscape, where the arid expanse of the Mojave Desert meets the state line. The diagonal boundary between Nevada and California bisects the quadrangle, passing through the Ivanpah Valley and near the settlement of Calada. To the south, the dry bed of Ivanpah Lake provides a stark contrast to the surrounding alluvial fans and mountain slopes. The map traces the infrastructure through this corridor, including the small outpost of Desert, illustrating the modern management of this interstate borderland. The township and range lines of t17n r15e and t27s r59e reveal the systematic grid overlaying the natural features of San Bernardino County.
