Investigating the origin of the ancestral Puebloans at Crow Canyon

Dirt under the fingernails, the fragrance of sage wafting in the air and the thrill of discovering an ancient artifact have made participating in a real archaeology dig at Crow Canyon Archaeological Center a popular draw.

Southwest Colorado is a mecca for archaeology buffs, with headliners Mesa Verde National Park, Hovenweep and Canyons of the Ancients national monuments and the Anasazi Heritage Center. In the middle of it all sits Crow Canyon, located just west of Cortez, a lesser-known institution that has spent the last 28 years conducting major archaeological research, teaching thousands of area schoolchildren and teachers and building bridges between the archaeological community and Native Americans. 

Since its founding in 1983, the center has conducted 11 major multiyear archaeological excavations, such as Sand Canyon Pueblo in Canyons of the Ancients and Goodman Point Pueblo at Hovenweep. They focused primarily on the Pueblo peoples circa A.D. 750 to 1300, learning that weather conditions, diminishing natural resources and unsustainable population sizes probably contributed to their dramatic departure. 

This spring, the organization started a new three-year research project about the significant Basketmaker III settlements in the Indian Camp Ranch subdivision going back even further, to A.D. 500 to 750. 

“We’re involved in one of the most exciting things happening in the Four Corners region,” Supervisory Archaeologist Shanna Diederichs said. “For the last 20 years, the 13th-century exodus of the ancestral Puebloans was one of the largest archaeology questions on the plate. Now we have some answers for that. 

“The next big question is ‘Where did they come from?’ We won’t know all the factors that led to that depopulation until we look at their initial settlement here.” 

While the project eventually will survey much of the subdivision, located just north of Crow Canyon, this summer’s dig focused on an 8-acre area named the Dillard Site, after site owner Jane Dillard. 

“It’s the earliest confirmed Basketmaker III great kiva in Southwest Colorado, and it dates to A.D. 650,” Diederichs said. “We found a wet-laid masonry wall. The Pueblo people didn’t start using masonry for another 250 years. It would have been the largest structure these people would have entered in their entire lives.” 

Many of the technological advancements of the ancestral Puebloan era started in that period. 

“It’s the rise of intensive agriculture of starchy maize,” she said. “They added beans and turkey to their diet. True pottery was invented so they could cook the beans. And the bow and arrow improved hunting over the atlatl (spear thrower) and the spear.” 

Out of the classroom 

Archaeological projects at Crow Canyon have two purposes: to learn more about the vanished people who once called this area home and to teach people of all ages about the archaeological process with a hands-on approach. Digs go more slowly as “crews” of program participants and interns come and go, but the thrill of discovery is always fresh.
