Rice Valley dominates the central portion of this Riverside County landscape, serving as a broad, arid basin between two prominent desert ranges. To the south, the intricate contours of the Big Maria Mountains rise sharply, while the northern edge of the map is defined by the southern reaches of the Riverside Mountains. This 2021 survey illustrates the stark geomorphology of the eastern California desert, highlighting the vast alluvial fans and drainage patterns that flow from the rocky heights into the valley floor. The map primarily documents the natural terrain and the administrative grid system, including t2s r21e and t3s r22e, which provide the essential spatial framework for this unpopulated corner of the Mojave Desert.
