プエブロ族はいつニューメキシコに到達した
The Pueblo people built a flourishing sedentary culture in the 13th century A.D., constructing small towns in the valley of the Rio Grande and pueblos nearby. By about 700 to 900 AD, the Pueblo began to abandon ancient pit houses dug in cliffs and to construct rectangular rooms arranged in apartment-like structures. By 1050 AD, they had developed planned villages composed of large terraced buildings, each with many rooms. These apartment-house villages were often constructed on defensive sites- on ledges of massive rock, on flat summits, or on steep-sided mesas, locations that would afford the Anasazi protection from their Northern enemies. The largest of these villages, Pueblo Bonito, in the Chaco Canyon of New Mexico, contained around 700 rooms in five stories and may have housed as many as 1000 persons. No larger apartment-house type construction would be seen on the continent until 19th century Chicago and New York. Then, around 1150, Chaco Anasazi society began to unravel. Long before the Spanish arrival, descendants of the Anasazi were using irrigation canals, check dams and hillside terracing as techniques for bringing water to what had for centuries been an arid, agriculturally marginal area. At the same time, the ceramic industry became more elaborate, cotton replaced yucca fiber as the main clothing material and basket weaving became more artistic.
