One of the more debated issues in western North American prehistory is the effect of postglacial maximum warmth and aridity on hunter-gatherer groups. Antevs described the Long Drought, or Altithermal, as a period of warmer than present conditions, with increased aridity, tat occurred between 7500 and 5000 bp. The decrease in effective moisture would have had deleterious effects on vegetative cover and animal populations as well as landscapes, due to increased erosion. Several scenarios about the impacts of climate of prehistoric groups of the region have been presented.
