added by archaeologs Late Archaic and Post-Archaic sedentary communities living in southwestern parts of North America between c. 1000 bc and ad 750 with three main phases. Basketmaker Phase I, dated to c. 1000-1 bc , is essentially the same as the Archaic. Basketmaker Phase II, c. ad 1-450, is the same as the Desert Archaic and represents the beginning of a long-lived cultural tradition on the Colorado Plateau, which is referred to as the Anasazi. Basketmaker Phase III, c. ad 450-750 equates to a developed phase of Anasazi, when beans were added to the diet and there was a greater commitment to agriculture.
