The Colorado Department of Transportation is redesigning the hazardous interchange between U.S. Highways 550 and 160 to the south of Durango, Colorado. Cultural consultation and mitigation for the project included a robust program of Native American participation and archaeological data recovery at four major prehistoric sites, including three Pueblo I habitations and a Pueblo II camp. Together, these sites contain at least 11 semi-subterranean structures with associated surface features and artifacts. This presentation will provide information about the project, discuss preliminary results, and provide a regional context through which to interpret the results.
