Cultural Periods of the Anasazi Indians...

Basket Maker I... ? B.C. to 500 A.D.
		Early nomadic populations in the Southwest lived in natural caves or make-shift shelters. This period is known as Basket Maker I.

Basket Maker II... 500 A.D.. to 700 A.D.
With the introduction of corn into the culture, development of agriculture began. The Indians started making stone-lined pits in the floors of caves in which to store their crops. This agricultural period is referred to by archaeologists as Basket Maker II.
Storage pits built towards the end of the Basket Maker period were larger than before, eventually developing into permanent dwellings in which large stone slabs, poles, and brush covered with plaster were used for walls.

Pueblo I and II... 700 A.D. to 1050 A.D.
		In the Pueblo I era, structures with several connected rooms developed and some houses were built above ground. With Pueblo II came the beginning of one-story houses surrounding a court. In the courtyard was a kiva which once had been the pit house.

Evolution of a Pit House to a Kiva...
				These plans show the evolution of a pit house into a kiva. The antechamber has been filled to form the ventilation stack for the kiva, then a ladder is used to enter through the roof.

Pueblo III - Great Pueblo Period... 1050 to 1300 A.D.
		Pueblo III, the Great Pueblo Period, was the era of the large housing clusters such as the pueblos of Chaco Canyon and the cliff dwellings of Mesa Verde. This was the period of the finest architecture and pottery.

Pueblo IV and V... 1300 A.D. to the Present
				The black area represents the Pueblo IV era .The white dots represent the Pueblo villages at the time of the arrival of the Spaniards. This began the Pueblo V, or the Historic Period.
The Pueblo IV period began with the migration of the people from Chaco Canyon and Mesa Verde to the Rio Grande in New Mexico and along the Little Colorado in Arizona. With the arrival of the Spaniards, Pueblo V, or the Historic Period, commenced. Grouped in this period are the modern Pueblo Indians who's villages can be seen today in New Mexico and the Hopi Mesas of Arizona
