Terraces and Retaining Walls
The terraces in front of the rooms occupying the floor of the cave are characteristic features of Cliff Palace ([pls. 9], [10]). The excavations revealed three of these terraces, of which the floor of the cave is the fourth. This fourth terrace, or cave floor, is in the main horizontal, but on account of the accumulated talus the slope from the southern end of the portion in front of kiva G was gradual and continued at about this level to the northern end of the ruin. This slope brought it about that kivas in the terraces are at different levels. The floors of kivas H and I lie on about the level of the first terrace, that of G on the terrace above, and F lies on the third terrace; the remaining kivas are all excavated in the cave floor, or fourth terrace. From the main entrance to the ruin, extending northward, there are representations of the second and third terraces, both of which extend to the cliff in front of kiva U. It is probable from the general appearance of the ruin that when all the terraces and walls were intact Cliff Palace was also terraced with houses along the front, which recalls architectural features in certain cliff-dwellings in Canyon de Chelly.
