From "Signs of Life, rock art of the upper Rio Grande" by Dennis Slifer
"The people we call Anasazis( a Navajo word meaning "Ancient Ones," or Ancient Enemies") originated on the Colorado Plateau from Desert Archaic people about 2,000 years ago.Their culture became the largest and best known of all prehistoric southwestern cultures. They were primarily a horticultural society, growing corn, beans, and squash for their food staples. The Basketmaker Period of the Anasazis preceded the Pueblo Period, the latter commencing around A.D. 700. Spectacular cliff dwellings and multistoried masonry pueblos with underground ceremonial chambers, known as Kivas, are the architectural characteristics of the classic Anasazi period. The Anasazi tradition spans a period from at least 200 B.C. to approximately A.D. 1540, when the Spanish entered the Southwest. Modern Pueblo peoples living along the Rio Grande, and at Hopi, Zuni, and Acoma, are descendants of the Anasazis.
Unlike many of their neighbors who shared common Desert Archaic origin and lifestyles, the Anasazi people exhibited a tendency to radical change throughout their history. Their culture became more complex with time, perhaps due in part to the well-documented contacts with the cultures of Mexico across the desert to the south, where maize, beans, and squash were first domesticated. These foods became the staples of village life throughout the southwest, and Anasazi civilization was supported by them. Many other developments from Mexico, and elsewhere, shaped Anasazi culture, including pottery, irrigation techniques, the bow and arrow, cotton and loom weaving, as well as esoteric knowledge and religious ideas...............
..........Today, there are 19 Pueblo Indian tribes with a combined population of 50,000. The Anasazis are alive and well in the Rio Grande Valley and at Acoma, Zuni, and Hopi, although some Pueblo people prefer the Hopi term "Hisatsinom" (Ancient People) to describe their ancestors.Despite four centuries of political domination by European- derived cultures, the Pueblo people still thrive and have preserved much of their ancient heritage."
