1925 Map of Douglas

About this map

The United States Mexico boundary line anchors this 1920s tactical map, revealing a frontier landscape shaped by ranching and regional transit. Dozens of family names—such as Wilkinson, Beck, and Decker—mark the scattered residences and homesteads that define the basin, while the Nacozari Railroad and the Borderland Highway provide the primary connections southward toward Sonora and westward to Bisbee. This era of the Arizona borderlands is characterized by localized infrastructure, evidenced by the presence of the Double Adobe Valley School and various irrigation structures like the Ditch and several Old Reservoirs. Military and industrial presence is noted through the A Brigade camp and the Quarry, while markers like Adobe Ruins and the Slaughter Camp reflect the deep ranching history of the Aqua Prieta River valley.
