Entering the cañon, Mr. Jackson continues: “Grouped along in clusters, and singly, were indications of former habitations, very nearly obliterated, and consisting mostly, in the first four or five miles, of the same mound-like forms noticed above, and accompanied always by the scattered, broken pottery. Among them we find one building of squared and carefully laid sandstone, one face only exposed of three or four courses, above the mass of _debris_ which covered every thing. This building lay within a few yards of the banks of the stream, was apparently about ten feet by eight, the usual size, as near as we could determine, of nearly all the separate rooms or houses in the larger blocks, none larger, and many not more than five feet square. The stones exposed are each about seven by twelve inches square, and four inches thick, those in their original position retaining correct angles, but, when thrown down, worn away by attrition to shapeless bowlders.” “As we progressed down the cañon the same general characteristics held good. The great majority of the ruins consisting of heaps of _debris_ a central mass considerably higher and more massive than the surrounding lines of sub-divided squares. Small buildings, not more than eight feet square, were often found standing alone apparently, no trace of any other being detected in their immediate neighborhood.” We would call especial attention in this description to the character of the ruins, the central, higher mass surrounded by other ruins; also to the houses found occasionally standing alone. We notice they are of the same general character as the ruins at Aztec Springs. We are finding abundant evidence that this section was once thickly settled. Going back to the triple-walled tower on the McElmo, Mr. Jackson says of the immediate vicinity: “On the mesa is group after group upon the same general plan, a great central tower and smaller surrounding buildings. They cover the whole breadth and length of the land, and, turn which way we would, we stumbled over the old mound and into the cellars, as we might call them, of these truly aborigines.” We believe, however, that no excavation for cellar purposes are found in the entire region covered by these ancient ruins. “Starting down the cañon (the McElmo), which gradually deepened as the table-land rose above us, we found upon either hand very old and faint vestiges of the homes of a forgotten people, but could give them no more attention than merely noting their existence.”
