Approximate location — plotted from published sources, not a site visit, and not a guarantee of access.
Vast remnant Pleistocene dry lake south of Willcox that hosts winter roosts of thousands of sandhill cranes and supports exceptional tiger-beetle diversity. Designated a National Natural Landmark; public wildlife viewing focuses on Arizona Game and Fish Department’s Willcox Playa Wildlife Area and nearby overlooks—not the restricted military proving-ground flats.
