The Tonopah Desert also lies between two plains: the narrow southeast ridgeline of the Belmont Mountains and the Hassayampa Plain are northeast. The west and southwest of the Tonopah Desert is connected to the southeast section of the large Harquahala Plain, northwest-southeast trending, the same lineage as the Centennial and Bouse Washes which drain the named plains, mountains, and the desert, (about twenty landforms in the region).
