About this map

Three Points and Robles Junction serve as the primary hubs in this desert landscape, where the flat basin meets the rising slopes of the Roskruge Mountains and Sierrita Mountains. The settlement pattern reflects the critical importance of water in this arid region, evidenced by a network of scattered resources like Beers Well, Spaulding Well, and Sierrita Tank. The Mary E Dill Sch stands as a community landmark at the central junction, while the surrounding terrain is marked by ranching infrastructure such as various corrals and the Diamond Bell Ranch Road.

Ephemeral drainages including Brawley Wash and Mendoza Wash define the hydrology of the area, cutting through the basin floor. Human activity is further indicated by more specialized features like a Rifle Range and a small Gravel Pit. The map also delineates an extensive grid of local streets, including Guy Street and Wells Fargo Road, illustrating the early residential layout of the high-desert valley.
