2018 Map of Ajo South

About this map

Mexican Town and Rowood sit at the northern edge of this high-desert landscape, dominated by the mining-related topography of Concentrator Hill. This 2018 survey documents a region defined by arid water management and rugged landforms, where the Little Ajo Mountains rise sharply above the Valley of the Ajo. Grounded in the copper-mining history of Pima County, the map details industrial infrastructure like Pipeline Rd alongside natural landmarks such as Arkansas Mtn and the distinctively shaped Locomotive Rock. Transportation through the area follows established desert corridors like Bates Well Road and Darby Well Road, which intersect near old watering points including Hotshot Tank and Eberling Tank. Drainage patterns across the basin are traced through the seasonal courses of Darby Arroyo and Gunsight Wash, providing a clear view of the water-stressed environment surrounding these historic settlements.
