I had some knowledge of the ethnology of the Hopi, derived from several summers' field work among them, and I believed this information could be successfully utilized in an attempt to solve certain archeological questions which presented themselves.[2] I desired, among other things, to obtain new information on the former extension, in one direction, of the ancestral abodes of certain clans of the sedentary people of Tusayan which are now limited to six pueblos in the northeastern part of the territory. In carrying out this general plan I made an examination of cliff dwellings and other ruins in Verde valley, and undertook an exploration of two old pueblos near the Hopi villages. The reason which determined my choice of the former as a field for investigation was a wish to obtain archeological data bearing on certain Tusayan traditions. It is claimed by the traditionists of Walpi, especially those of the Patki[3] or Water-house phratry, that their ancestors came from a land far to the south of Tusayan, to which they give the name Palatkwabi. The situation of this mythic place is a matter of considerable conjecture, but it was thought that an archeological examination of the country at or near the headwaters of the Rio Verde and its tributaries might shed light on this tradition. It is not claimed, however, that all the ancestors of the Tusayan people migrated from the south, nor do I believe that those who came from that direction necessarily passed through Verde valley. Some, no doubt, came from Tonto Basin, but I believe it can be shown that a continuous line of ruins, similar in details of architecture, extend along this river from its junction with Salt river to well-established prehistoric dwelling places of the Hopi people. Similar lines may likewise be traced along other northern tributaries of the Salt or the Gila, which may be found to indicate early migration stages. The ruins of Verde valley were discovered in 1854 by Antoine Leroux, a celebrated guide and trapper of his time, and were thus described by Whipple, Ewbank, and Turner in the following year: The river banks were covered with ruins of stone houses and regular fortifications; which, he [Leroux] says, appeared to have been the work of civilized men, but had not been occupied for centuries. They were built upon the most fertile tracts of the valley, where were signs of acequias and of cultivation. The walls were of solid masonry, of rectangular form, some twenty or thirty paces in length, and yet remaining ten or fifteen feet in height. The buildings were of two stories, with small apertures or loopholes for defence when besieged.... In other respects, however, Leroux says that they reminded him of the great pueblos of the Moquinos.[4]
