Crow Canyon Archaeological Centeris gearing up for their 2016 excavation season at a group of sites north of Cortez that may hold clues about the changes that prehistoric inhabitants of the area were going through in the seventh and eighth centuries. KSJD's Tom Yoder talked with Caitlin Sommer, supervisory archaeologist at Crow Canyon Archaeological Center, about their work at the sites so far, and what they hope to learn during their investigations this year.
