Three Points and Robles Junction serve as the primary hubs in this arid landscape, where the intersection of major roads meets a network of desert washes. The drainage system is dominated by Brawley Wash and Mendoza Wash, which channel seasonal water between the Roskruge Mountains to the west and the Sierrita Mountains to the southeast. Water access is critical in this environment, evidenced by the numerous named wells and tanks scattered across the map, such as Santa Teresa Well, Spaulding Well, and San Juan Tank.
