1/4 Section Pueblito, Farmington District BLM

This project was conducted by the 2002 Geosciences 597J course at the Laboratory of Tree-ring Research, the University of Arizona with tremendous assistance from the Farmington Bureau of Land Management.

The goals of the project were to (a) provide students and professionals with experience in the collection, preparation, crossdating, and interpretation of archaeological tree-ring samples, and (b) to generate chronological and behavioral interpretations of ¼ Section Pueblito.
