Can this Ultimate Field Trip solve the ultimate mystery?
Ancestral Puebloan people lived in the Mesa Verde region of Colorado for over a thousand years, then suddenly moved away around A.D. 1300. join this group of eighth-grade students as they go on the Ultimate Field Trip and search for answers to this ancient mystery.
The students help archaeologists digging in the ruins for clues. As they spend a week at the Crow Canyon Archaeological Center, they learn about life in the desert, and the history of the ancestral Puebloans. And the kids' study of archaeology leads them to the biggest question of all about the ancient Indians: What happened to them, and why did they disappear?
