1992 Map of Three Points

About this map

Three Points and Robles Junction anchor this desert landscape at the intersection of critical transit routes in Pima County. The terrain is defined by the broad drainage patterns of Brawley Wash and Mendoza Wash, which cut through the alluvial plains between the Roskruge Mountains to the west and the Sierrita Mountains to the southeast. The 1990s layout reflects a transition from traditional ranching and utility infrastructure toward residential development, particularly evident in the grid of streets south of Diamond Bell Ranch Road, including Vance Blvd and Barron Blvd. Rural water management remains central to the area's utility, marked by numerous cattle tanks and wells such as Javelina Tank, San Juan Tank, and the San Juan Well. Industrial and recreational footprints are also visible, from the Firing Range near the western foothills to the Corner Windmill and various gravel pits that served the region's infrastructure needs.
