As early as the twelfth century A.D., the settlements of Chaco Canyon in New Mexico in the American Southwest were notable for their "great houses," massive stone buildings that contain hundreds of rooms and often stand three or four stories high. Archaeologists have been trying to determine how the buildings were used. While there is still no universally agreed upon explanation, there are three competing theories.
One theory holds that the Chaco structures were purely residential, with each housing hundreds of people. Supporters of this theory have interpreted Chaco great houses as earlier versions of the architecture seen in more recent Southwest societies. In particular, the Chaco houses appear strikingly similar to the large, well-known "apartment buildings" at Taos, New Mexico, in which many people have been living for centuries.
A second theory contends that the Chaco structures were used to store food supplies. One of the main crops of the Chaco people was grain maize, which could be stored for long periods of time without spoiling and could serve as a long-lasting supply of food. The supplies of maize had to be stored somewhere, and the size of the great houses would make them very suitable for the purpose.
A third theory proposes that houses were used as ceremonial centers. Close to one house, called Pueblo Alto, archaeologists identified an enormous mound formed by a pile of old material. Excavations of the mound revealed deposits containing a surprisingly large number of broken pots. This finding has been interpreted as evidence that people gathered at Pueblo Alto for special ceremonies. At the ceremonies, they ate festive meals and then discarded the pots in which the meals had been prepared or served. Such ceremonies have been documented for other Native American cultures.
The article and the lecture are about how the great houses of Chaco structure were used. The article states three theories about Chaco’s great houses. However, the lecture refutes all theories.
From the reading, the first theory is that the Chaco structures were truly accommodation. The speaker agrees that the outside of the building look like the resident. However, he explain that inside of the building are not suitable for hundreds people to live in because there are only ten fire places that is not enough for hundreds people.
Second, the author mentions the second theory, which states that the buildings were used to store food. The lecturer said that there are no supported evidences. If the buildings were used to store the crops, the trace of the maize and the containers should be found.
Third, the article avers third theory about using the building as a ceremonial center. The professor opposes this idea by saying that the pots found in the mound were probable used to construct the house. In addition, there are many construction materials and tools were found in the mound.
