1949 Map of Winkelman

About this map

Industrial and ranching interests meet at the confluence of the Gila River and the San Pedro River in this mid-century portrait of southern Arizona. The mining operations at Hayden are clearly defined by a massive Tailings Pond and the complex infrastructure of the Southern Pacific and San Manuel Arizona Railroad lines. While Winkelman and Dudleyville serve as the primary population centers along the riverbanks, the surrounding high ground of the Tortilla Mountains reveals a more isolated existence. Evidence of the region's earlier cattle and extraction history is found in several defunct sites, including the Romero Ranch (Aban'd), Antelope Mine (Aban'd), and Sample Mine (Aban'd). The map also marks an Old Indian Treaty Boundary cutting across the San Pedro valley, highlighting the historical administrative layers of the Pinal and Gila county borderlands.
