1981 Map of Patagonia

Water management is vital to this arid environment, evidenced by the presence of Patagonia Lake and Patagonia Lake State Park along Sonoita Creek. The map documents a transition from industrial activity to recreation and conservation, with family-named outposts like Hard Luck Ranch and Weatherhead Ranch scattered through the canyons. The complex topography includes notable peaks like Salero Mtn and the distinct Castle Butte, while old boundaries like the Baca Float No 3 hint at the area's complicated Spanish land grant history.
