Moen-kopi was the headquarters of a large business enterprise of the Mormons a number of years ago. They attempted to concentrate the product of the Navajo wool trade at this point and to establish here a completely appointed woolen mill. Water was brought from a series of reservoirs built in a small valley several miles away, and was conducted to a point on the Moen-kopi knoll, near the end of the south row of houses, where the ditch terminated in a solidly constructed box of masonry. From this in turn the water was delivered through a large pipe to a turbine wheel, which furnished the motive power for the works. The ditch and masonry are shown on the ground plan of the village (Pl. XLIII). This mill was a large stone building, and no expense was spared in fitting it up with the most complete machinery. At the time of our visit the whole establishment had been abandoned for some years and was rapidly going to decay. The frames had been torn from the windows, and both the floor of the building and the ground in its vicinity were strewn with fragments of expensive machinery, broken cog-wheels, shafts, etc. This building is shown in Pl. XLV, and may serve as an illustration of the contrast between Tusayan masonry and modern stonemason’s work carried out with the same material. The comparison, however, is not entirely fair, as applied to the pueblo builders in general, as the Tusayan mason is unusually careless in his work. Many old examples are seen in which the finish of the walls compares very favorably with the American mason’s work, though the result is attained in a wholly different manner, viz, by close and careful chinking with numberless small tablets of stone. This process brings the wall to a remarkably smooth and even surface, the joints almost disappearing in the mosaic-like effect of the wall mass. The masonry of Moen-kopi is more than ordinarily rough, as the small village was probably built hastily and used for temporary occupation as a farming center. In the winter the place is usually abandoned, the few families occupying it during the farming months returning to Oraibi for the season of festivities and ceremonials. CHAPTER III. RUINS AND INHABITED VILLAGES OF CIBOLA. PHYSICAL FEATURES OF THE PROVINCE. Though the surroundings of the Cibolan pueblos and ruins exhibit the ordinary characteristics of plateau scenery, they have not the monotonous and forbidding aspect that characterizes the mesas and valleys of Tusayan. The dusty sage brush and the stunted cedar and piñon, as in Tusayan, form a conspicuous feature of the landscape, but the cliffs are often diversified in color, being in cases composed of alternating bands of light gray and dark red sandstone, which impart a considerable variety of tints to the landscape. The contrast is heightened by the proximity of the Zuñi Mountains, an extensive timber-bearing range that approaches within 12 miles of Zuñi, narrowing down the extent of the surrounding arid region.
