1966 Map of Ninetysix Hills NE

About this map

Ninetysx Hills and the Box O Hills define this arid landscape in Pinal County, where seasonal drainage patterns and ranching infrastructure tell the story of mid-century land use. The presence of Helmwheel Ranch and Horse Ranch indicates the grazing economy that persisted through the 1960s, supported by an extensive network of water tanks such as The Lake Tank, Eight Section Tank, and D Bar H Tank. These features are connected by primitive transportation routes, including Barkerville Road and Lambing Camp Road, which navigate through several major dry washes like Donnelly Wash and Cottonwood Wash. The map reflects a period before significant modern development, preserving the original nomenclature of local ranching families and topographical landmarks.
