About the Chaco Anasazi

The Chaco Anasazi emerged in the northern U.S. Southwest around approximately A.D. 900 from earlier Anasazi roots. They subsequently developed a fascinating culture that appears to have been focused on Chaco Canyon in northwestern New Mexico. Featuring lengthy roadways, impressive monumental architecture, astronomical observatories, and a far-ranging exchange system, the Chaco Anasazi continued to develop until approximately A.D. 1150, at which point their distinctive culture disappeared. Researchers interested in the Chaco Anasazi are attempting to answer questions ranging from the origins of this tradition to the reasons for its downfall.

One of the most important sources of information that is helping to answer questions about the Chaco Anasazi are the "outliers," which are also known as "great house communities." These communities exhibit a series of features that archaeologists believe associate them with the Chaco phenomenon, including monumental masonry great houses, subterranean great kivas, and a distinctive array of ceramics and exchange goods. Although undervalued in early research on the Anasazi, over the past two decades scholars have increasingly turned their attention to the great house communities.

Subsequently, more and more suspected great house communities are being identified every year, so many that keeping track of them and verifying their identification as Chaco Anasazi has been difficult.

Be forewarned that this database is not guaranteed to have the most up-to-date, reliable information on each Chaco Anasazi great house community. Rather, it serves as a starting point that should be supplemented with additional research. Descriptions of all of the variables are available, and should be consulted. Also, in order to make the origins of the information as explicit as possible, each entry in the database has an extensive notes section.

About the Database

In 1999, 10 archaeologists whose research is on the Chaco Anasazi worked together to assemble a comprehensive database reflecting what was known about great houses and the communities in which they were built. Each archaeologist focused his or her attention on the region of the Southwest that they knew best, reviewing records for every great house in that area. A standardized set of variables was collected, and each participant also added annotated information and references for each great house. The resulting database served as a focus for discussions when about 18 archaeologists met at Arizona State University to consider issues related to Chaco Anasazi patterns outside of Chaco Canyon. This meeting, called "The Chaco World Conference", was sponsored by the National Park Service, University of Colorado, and Arizona State University. It was one of several such seminars that took place around the Southwest as part of the final stage of The Chaco Center research project, which investigated Chaco Canyon during the 1970s and 1980s.

In 2001, the National Center for Preservation Training and Technology awarded a grant to build a complete online spatial database using the results of the 1999 Chaco World Conference. This spatial database, which is being built using ESRI's ArcIMS software, is slowly being put online.
