Dominguez Archaeological Research Group began building chronometric databases in 2005 and first made them available on the internet in 2012. The emphasis has been on the Four-Corners states with some overlap into adjoining areas.
The radiocarbon database currently contains 2327 sites and 9426 dates. The tree-ring database contains 1380 sites and 34,166 dates. Both databases are updated as new information comes to light.
The current version of the radiocarbon database emphasizes sites associated with the Early Agricultural Period (EAP) from Northern Mexico to the Upper San Juan region in the Four-Corners states. The intent is to interpret and resolve the many research questions that have been posed regarding the processes of maize dispersion within the American Southwest.
You are encouraged to contribute data by submitting new or corrected information via email to the Project Director.

The Radiocarbon and Tree-Ring database projects were initially funded in part by State Historical Fund grants from History Colorado, the Colorado Historical Society.
