Based on findings from excavation projects that began in 1977 and ended in 1986 on lands at Fort Bliss, Texas, this study focuses on two particular sites: Turquoise Ridge and the Huesito site. One major topic of discussion is the role of residential mobility in late prehistoric adaptations. Residential mobility had always been assumed for the region’s earliest populations, but the idea that it figured in later adaptive strategies was of more recent origin.
