Moving out of the Archaic on the Edge of the Southwest

Abstract

The transition from mobile foragers to sedentary farmers was not made to the same degree all over the southwestern United States and northern Mexico. The deserts of the Jornada Mogollon region illustrate the persistence of some aspects of mobile adaptations through the first millennium A.D., as both Jornada Archaic peoples and their ceramic-using successors made use of a seasonal mobility pattern to cope with the region's arid conditions. Use of winter base camps and mobility during the rest of the year are apparent in both cases, but important differences can also be detected. This study combines old and new data to show how the two adaptations differed in the extent to which winter camps were used, in type and intensity of winter provisioning strategies, and in patterns of community organization. All these changes are argued to be logical precursors to the short-lived agricultural adaptation that appeared in the area after A.D. 1100. Moreover, such adaptations may characterize a large portion of the desert Southwest and northern Mexico.
