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.
Both the reading and the lecture are discussing some hypotheses about how the Chao Canyon buildings were used through that time. The author of the reading presents three possible theories that describe the usages of these buildings. Nevertheless, the lecturer finds the putative theories unconvincing and debunks them one by one.
First of all, the writer contends that one theory states that these buildings were residential. It has been mentioned that there were about 100 people living in these houses and the architecture of the buildings supports this idea. The lecturer rebuts this argument. He accentuates the fact that if these buildings were residential, there must have been more fireplaces to support daily cooking for 100 people. However, evidence shows that the fireplaces were only enough to support 10 families, and the idea that these buildings were residential is totally implausible.
Secondly, the reading passage holds the view that these buildings were probably used for storing grains. The author states that at that time, grain maize was the main crop of people and since it could have been stored for long periods and needed large storing areas, the buildings were used to keep these grains. Conversely, the lecturer brings up the idea that this theorem is unsupported by the evidence. Actually, he notes that if these buildings were used for storing the crops, there should exist spoiled maize crops or even grain containers that support this idea. However, due to the lack of the remains of containers and grains, this hypothesis is not supported at all.
Finally, the passage alleges that these houses were used for ceremonies and festivals. It has been stated that there existed a large number of broken pots that supports the idea of holding special ceremonies in the mentioned buildings. Contrary to this, the professor notes that apart from broken pots, there were lots of various materials existing in the buildings. He mentions that archeologists found constructive tools, different materials, and also pots in the buildings which may have been used by construction workers, and these remains of pots and tools are just regular trashes and don't support any ceremonial activities.
