Resumo

Southwestern archaeologists generally agree with Jett's opinion that more than one cause was involved in the widespread 13th-century Pueblo migrations, but they may disagree with his emphasis on the influence of non-Pueblo enemy groups, for which actual evidence remains meager, and his de-emphasis on the effect of known drought conditions. A serious specific error, however, lies in his use of the 'Flagstaff' (Pueblo Plateau) tree-ring record for prehistoric weather fluctuation in areas of the Rio Grande and southern Arizona, since these are completely outside the area defined by Douglass, Schulman, and others for the 'Flagstaff' chart. Past weather conditions in the Rio Grande frequently contrasted or differed in degree of wet and dry periods, as indicated by the Rio Grande tree-ring chart, and some areas of the Southwest still are not covered by charts.
