Willcox Playa, the largest "dry lake" in Arizona, is a remnant of the pluvial Lake Cochise. Unlike similar dry lakes, the black mud below the surface contains a rich fossil pollen record of the pluvial periods of the Pleistocene. The site has become a night-time roosting area for 4,000-8,000 sandhill cranes and contains the greatest diversity of tiger beetles in the United States.
