Compiled Tree-ring Dates from the Southwestern United States (Restricted)

Creator(s): Timothy A. Kohler; R. Kyle Bocinsky

Year: 2016

Summary

This database contains 32863 tree ring dates from archaeological sites in new Mexico, Arizona, Colorado and Utah that Kohler was able to collect. All date determinations were made by the Laboratory for Tree Ring Research at the University of Arizona. The database contains site numbers and site names, lab (LTRR) numbers, references where available, the outer date (AD), the outer symbol, and the confidence level. This confidential version of the database contains site locations; the public version (tDAR ID 399313) has site numbers (so locational information can be obtained from the proper authorities) but no locational data (to protect the archaeological sites). To obtain access to this confidential version with site locations, you must demonstrate that you have permission from the managers of the statewide site files in the four states.
