1979 Map of Three Points

About this map

Robles Junction, situated at the intersection of State Routes 86 and 286, serves as the primary hub of this arid Pima County landscape in the late 1970s. The community of Three Points centers around the Mary E Dill Sch and a local substation, while the surrounding desert terrain is defined by an extensive network of washes, including Brawley Wash and Mendoza Wash. To the south and west, the development of the Diamond Bell Ranch Road and several residential streets like Chumbler Road and Guy Street suggest the early stages of rural subdivision amidst traditional ranching operations. The map reveals the critical importance of water management in this environment, evidenced by numerous named sources such as Beers Well, Santa Teresa Well, and Javelina Tank. To the northwest, the foothills of the Roskruge Mountains provide a backdrop to more specialized sites, including a Rifle Range and several prospects.
