Blurb: "Before it was abandoned 900 years ago, the Grewe Site was one of the largest settlements in the American Southwest.

This video describes the excavation of the Grewe Site by Northland Research in a highway-related project sponsored by the Arizona Department of Transportation and the Federal Highway Administration."
