Borax Flat and the expansive basin of Searles Valley dominate this landscape, sitting at the junction of the Inyo and San Bernardino county line. The settlement of Trona serves as the primary hub, surrounded by a network of industrial and access roads like Stockwell Mine Rd and Copper Queen Canyon Rd that lead into the high desert terrain. The area is hemmed in by the Argus Range to the west and the Slate Range to the east, with distinctive geological features such as Trona Reef and Point of Rocks marking the transition from the valley floor to the desert uplands.
