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 reading and the lecture are both about the settlements of Chaco Canyon and how these buildings were used. Both claims that, there are no clear answer for the question. But the professor argues that non of the theories pointed out in the passage has strong scientific evidence.
The first theory states that the buildings were used for residential purpose and hundreds of people lived in one house. However, the professor points out that, inside structure of these houses does not support this claim as there are no enough fire places for hundreds of people. She states that even though there are many large rooms, number of fire places could had been sufficed at most for ten families.
Second passage suggest that these structures were used to store foods, especially "grain maize". But professor states that, evidence found from excavations does not support this theory, as up to date there are no reports of finding maize or maize containers from the site. Furthermore, she states that if these were used to store grain maize there should be abundance of maize containers. Therefore she casts doubt on this theory.
Final theory states that these houses were used as ceremonial centers. Passage states this because archaeologists have found large number of broken pots from the site "Pueblo Alto". However professor contradicts this by saying that archaeologists also have found many other types of artifacts from the site. Sans, stones, construction tools are among these, which suggest that this could not be a ceremonial site. Moreover, professor states that this might be a construction site.
In conclusion, although reading provides three theories about how the Chaco Canyon great houses were used, professor provides concrete evidence to refute those theories. Therefore still the question still remains unanswered.
