Overview

NCALM Seed Project. PI: Wetherbee Dorshow, University of New Mexico. The area of interest is defined by an irregular polygon with an area of 39.3 km2. The polygon follows a segment of the Chaco Canyon, NM and is located approximately 160 km northwest of Albuquerque, NM and 85 km Southeast of Farmington, NM. The data were collected to simulate dynamic hydrological processes in archaeological contexts.
