This large ruin,[35] so named from the finding of the cradle described and illustrated herein, is situated in the side of a bluff rising above East canyon. It contains about 50 rooms and at least 3 circular kivas without pilasters, the front walls of which are considerably broken down. The rooms of Cradle House as a rule extend along the rear of the cave, their back walls generally being formed by the vertical wall of the cliff, there being no recess behind them. The majority of the rooms lie about midway in the length of the ruin, the kivas being situated in front of the cluster. In two or three places rooms are found on levels below or above that of the main cluster, but only rarely are there rooms in front of others on the same level. On the upper ledge near the western end a small bin is found at the base of which is a considerable depression, probably artificial. LADDER HOUSE The more or less dilapidated walls of this ruin are to be seen from the left bank of East canyon, a few miles farther upstream. The position is indicated by an enormous butte which projects into the canyon and diverts the stream at that point. One side of this butte is eroded in such a way as to resemble in outline an elephant’s trunk, this erosion marking the initial process in the formation of a “natural bridge.” On the opposite side of this butte there is another large cliff-dwelling, which was not visited.

Some of the walls are in the form of concentric semicircles with the conspicuous representation of a head attached to one side. Many rocks have fallen on this ruin from the cave roof, especially at one end, but the rooms at the western end are still well preserved. PINE-TREE HOUSE About 8 miles up East canyon there is a large, almost inaccessible, ruin, which lies a short distance from the main canyon. A striking feature of this ruin is its division into three parts, of which the central section is somewhat lower than the one on each side. A large pine on the edge of the cliff above has suggested the name Pine-tree House. Deep below this ruin is a large basin, in which grow many trees and bushes; among these are a good spring and a small rivulet. This ruin has two very large circular kivas, without pedestals, 20 to 30 feet in diameter. A deep banquette is present on one side. This ruin exhibits no evidence of having been dug.
