The Double Adobe Site is an archaeological site in southern Arizona, twelve miles northwest of Douglas in the Whitewater Draw area. In October 1926, just three months after the first human artifact was uncovered at the Folsom Site, Byron Cummings, first Head of the Archaeology Department at the University of Arizona, led four students to Whitewater Draw. Discovered by a schoolboy, the Double Adobe site contained the skull of a mammoth overlying a sand layer containing stone artifacts. One of these students was Emil Haury. The Double Adobe Site was declared a National Historic Landmark in 1961.
