Reevaluation of Early Cochise Artifact Associations with Pleistocene Lake Cochise, Southeastern Arizona
Published online by Cambridge University Press: 20 January 2017
Abstract
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.
Résumé
Los materiales pertenecientes a la fase Sulphur Spring de la cultura Cochise, fueron previamente identificados en la orilla prominente (1.274 m) del lago pleistoceno Cochise, en el sureste de Arizona. Se ha sugerido que estos restos.fechados alrededor de 12.000–11.000 años de antigüedad, representan una manifestación arcaica temprana, depositada en antiguas gravillas de playa, posiblemente contemporánea con los niveles Clovis de los sitios Lehner y Naco. Nuevos datos basados en análisis estratigráfico, fechas radiocarbonicas correlacionadas, y restos artefactuales indican que la asociación de los artefactos de la fase Sulpher Spring con la orilla del lago Cochise es problemática.
