Cliff-dwellings were found scattered thickly throughout the whole region explored, from the heads of the tributary canons to their mouths, and all along the course of Montezuma Creek itself.

The two or three pueblos which we noticed in those regions were very small, and had every appearance of having been merely temporary affairs.
