Hovenweep National Monument protects five prehistoric ancestral Puebloan canyon-head villages located along a 16-mile stretch of land intersecting the Utah-Colorado border. For reasons not completely understood, in the late 1100s and early 1200s, widely dispersed people began consolidating into communities around water sources located at or near canyon heads. This appears to have intensified with the onset of an increasingly arid period.
