The ruins described in this chapter comprise but a few of those found within the province of Tusayan. These were surveyed and recorded on account of their close traditional connection with the present villages, and for the sake of the light that they might throw upon the relation of the modern pueblos to the innumerable stone buildings of unknown date so widely distributed over the southwestern plateau country. Such traditional connection with the present peoples could probably be established for many more of the ruins of this country by investigations similar to those conducted by Mr. Stephen in the Tusayan group; but this phase of the subject was not included in our work. In the search for purely architectural evidence among these ruins it must be confessed that the data have proved disappointingly meager. No trace of the numerous constructive details that interest the student of pueblo architecture in the modern villages can be seen in the low mounds of broken down masonry that remain in most of the ancient villages of Tusayan. But little masonry remains standing in even the best preserved of these ruins, and villages known to have been occupied within two centuries are not distinguishable from the remains to which distinct tradition (save that they were in the same condition when the first people of the narrators’ gens came to this region) no longer clings. Though but little architectural information is to be derived from these ruins beyond such as is conveyed by the condition and character of the masonry and the general distribution of the plan, the plans and relation to the topography are recorded as forming, in connection with the traditions, a more complete account than can perhaps be obtained later. In our study of architectural details, when a comparison is suggested between the practice at Tusayan and that of the ancient builders, our illustrations for the latter must often be drawn from other portions of the builders’ territory where better preserved remains furnish the necessary data.
