We read about the large stone structures, or “great houses,” in the Chaco Canyon and the three theories on which their existence is based. The professor in the lecture presents three reasons, one for each theory, as to why the origin of the large houses remains unknown.
The professor begins with the first theory on the structures as apartment buildings. The main flaw in this theory is that while there are indeed many rooms for a large number of inhabitants, there are relatively few fireplaces. If there had been residents, there would have had to have been enough fireplaces for each family.
The second theory proposes that the buildings stored corn. The lecturer explains that there were very few containers among the remains and little corn. Therefore, if these structures were for storage of maize, excavators would have found much more corn and many more ceramic containers.
Third and finally, the professor rebuts the proposal that this had been a ceremonial center. There are many remnants in addition to any possible religious artifacts, and the random distribution of the remains suggests just as likely that this was simply a trash heap.
