Herrera,[1] and also by Clavigero.[2] If by the word Aztlan was intended "place of Cranes", and on the supposition that these tribes migrated from the San Juan region, the reasons for the designation are justified. The Sandhill Crane (Grus Canadensis) is one of the largest and most conspicuous of American birds, and is still found from the British Possessions to New Mexico, and winters in the latter. I saw a pair of these great birds in 1878, in the valley of the Animas River. Dr. Coues remarks that "thousands of Sandhill Cranes repair each year to the Colorado River Valley, flock succeeding flock along the course of the great stream from their arrival in September until their departure the following spring. Taller than the Wood Ibises or the largest Herons with which they are associated, the stately birds stand in the foreground of the scenery of the valley. * * * Such ponderous bodies moving with slowly-beating wings give a great idea of momentum from mere weight, a force of motion without swiftness; for they plod along heavily, seeming to need every inch of their ample wings to sustain themselves"[3] It is an Indian trait to mark localities by some conspicuous feature or fact, and the selection of the Sandhill Crane to indicate their home country would have accorded with Indian usages.
Again, Herrera, who presents the current traditions, observes, that "these peoples painted their original in the manner of a cave, and said they came out of seven caves to people the country of Mexico. * * * After the six above mentioned races departed from their country, and settled in New Spain, where they were much increased, the seventh race being the Mexican nation, a warlike and polite people, who adoring their god Vitsilpuztli, he commanded them to leave their own country, promising them they should rule over other races in a plentiful country, and much wealth."[4]
It is worthy of remark that the cave dwellings or cliff houses are in the San Juan district, the most of them being on the Mancos River, and on the western portion of the San Juan. These traditions may in fact refer to these cave dwellings as the original homes of their ancestors, and at the same time without precluding the supposition that they also constructed
