The activity in photographing Cliff Palace has done much to make known its existence and structure. Many excellent photographs of the ruin have been taken, among which may be mentioned those of Chapin, Nordenskiöld, Vreeland, Nusbaum, and others. Oil paintings, some of which are copied from photographs, others made from the ruin itself, adorn the walls of some of our museums. Almost every visitor to the Mesa Verde carries with him a camera, and many good postal cards with views of the ruin are on the market. Negatives of Cliff Palace taken before its excavation and repair will become more valuable as time passes, because they can no longer be duplicated. From a study of a considerable number of these photographs it seems that very little change has taken place in the condition of the ruin between the time the first pictures were made and the repair work was begun. SITE OF CLIFF PALACE Cliff Palace is situated in a cave in Cliff-palace canyon, a branch of Cliff canyon, which is here about 200 feet deep. It occupies practically the whole of the cave, the roof of which overhangs about two-thirds of the ruin, projecting considerably beyond its middle. This cave is much more capacious than that in which Spruce-tree House is situated, as shown by comparing illustrations and descriptions of the latter in the former report. The configuration of Spruce-tree House cave and that of Cliff Palace, and the relation of its floor to the talus, also differ. The canyon in which Cliff Palace lies is thickly wooded, having many cedars and a few pines and scrub oaks; the almost total failure of water at certain seasons of the year at Cliff Palace renders floral life in the vicinity less exuberant than in Spruce-tree canyon, a branch of Navaho canyon (fig. 1). On the level plateau above the ruin there are many trees--pines and cedars--but even this area is not so thickly wooded as the summit of the mesa above Spruce-tree House.[15] [Footnote 15: Clearings in the forest indicate the positions of the former farms of the inhabitants of Cliff Palace.] [Illustration: PLATE 7 PHOTOGRAPHED BY R.
