The Laboratory of Tree-ring Research at the University of Arizona is pleased to offer its 7^th annual pre-session course devoted entirely to the collection, analysis, and interpretation of archaeological tree-rings. Participants (undergrads, grads, professionals) will learn the most accurate and precise dating method used by archaeologists via lectures, laboratory exercises, and field work. The centerpiece of this intensive 3-week course is a field trip to various archaeological sites in western New Mexico led by Drs. Ronald H. Towner and Jeffrey S. Dean. The first week in Tucson will provide participants with a basic background in dendroarchaeology. During the third week back in Tucson, participants will prepare, crossdate, and interpret the dendroarchaeological samples collected during the field trip.
