Materials belonging to the Sulphur Spring stage of the Cochise culture previously were identified on the prominent 1,274 m shoreline of Pleistocene Lake Cochise in southeastern Arizona. Dated ca. 12,000 to 11,000 years ago, the remains were suggested to represent an early Archaic manifestation deposited in ancient beach gravels, possibly contemporary with Clovis levels at the Lehner and Naco sites. New data based on stratigraphic analysis, correlated radiocarbon dates, together with artifactual remains indicate that the association of Sulphur Spring stage artifacts with the shoreline of Lake Cochise is problematical.
