In this monumental work, Jane Holden Kelley preserved archaeological data from many important sites in southeastern New Mexico, many of which no longer exist. She also established a basic chronological framework for the upland portion of this area. Sites discussed include Bloom Mound and the Bonnell site, as well as many sites in the Upper Gallo Drainage, the Upper Hondo Drainage, the Upper Macho Drainage, and north of Capitan Mountain.
