The Stepladder Mountains dominate the western portion of this San Bernardino County landscape, rising sharply above the arid floor of the Mojave Desert. This 2021 survey illustrates the stark topographical transition from the high relief of the mountains to the drainage systems of the Chemehuevi Valley in the east. The primary drainage feature, Chemehuevi Wash, meanders through the eastern section, tracing the natural path of seasonal runoff toward the valley floor. The map is defined by its traditional Public Land Survey System divisions, including sections within t6n r20e and t6n r21e, which provide a precise grid for modern land management in this uninhabited desert region.
