Abstract
Certain characteristics of the culture(s) of nomads are discussed and to these are attributed the concentration of archaeological work in north‐eastern Mexico upon excavation of sheltered sites. By presenting and comparing cultural traits for which there is evidence from both the early archival sources and the archaeological record, a reasonably viable and sensitive picture of aboriginal culture in north‐eastern Mexico is given. These data serve to emphasize the long duration and the remarkable similarity and conservatism of nomad culture in the area over a period of some 9,000 years, from about 7500 B.C. to the time of the Spanish entradas in the early seventeenth century.
