This kiva stands on an elevated rock, and has double walls, the intervals between the wall of the kiva and the outside walls being filled with rubble.
The height of kiva T is 7 feet 6 inches, that of one of the pilasters 6 feet 6 inches. The banquette is 3 feet 9 inches above the floor. The diameter of the kiva is 10 feet 5 inches. There were probably 6 pilasters and 2 mural niches. Although the greater part of the walls of this kiva was destroyed, a deep banquette still remains above the air shaft. The floor has the same level as the second terrace, or one story above kiva S, the roof of which is consequently at the level of the floor of kiva T.
Kiva T was in bad condition when work began, as part of its front wall had fallen and only the tops of the others were visible above the débris. Even the floor level was difficult to determine.
KIVA U
The form of kiva U is round, and its height is 7 feet 6 inches. The height of one of the pilasters is 4 feet 11 inches, and that of the banquette 3 feet 4 inches. The diameter of the kiva is 12 feet. There are 5 pilasters. The fire-hole is 4 inches from the flue; the diameter of the fire-hole is 20 inches, its depth 6 inches. There are 6 mural niches, so arranged that two large niches are situated above two small ones. The presence of but 5 pedestals is accounted for by the joining of 2 above the flue. Much rock-cutting was necessary in constructing this kiva, especially on the northern and southwestern sides. As the front wall of the kiva had fallen, it had to be practically rebuilt. The foundations were unstable, apparently having been constructed on loose stones carelessly laid.
KIVA V
This kiva is round and measures 5 feet 6 inches from the floor to the top of one of the pilasters. The top of the banquette is 3 feet 4 inches above the floor. The diameter of the kiva is 12 feet 8 inches. The number of pilasters is 6 and their average breadth 20 inches.
The distance from the deflector to the line of the wall is 23 inches; the height, of the deflector is 22 inches, the thickness 9 inches, and the width 3 feet 2 inches. The fire-hole is 18 inches from the sipapû; the latter is 10 inches deep and 3 inches in diameter, and is lined with a pottery tube cemented in place. There are three mural niches.
Kiva V is exceptional in the amount of rock-cutting that was necessary for lowering the floor to the desired level. Probably the greatest amount of stone-cutting was done in this kiva.
There remains to be mentioned a unique tunnel which may eventually throw some light on ceremonial openings in the kivas of cliff-dwellings. Just beneath the adobe floor, extending from a vertical flue outside the kiva to the fire-hole, which it does not, however, enter, there is a passage through which a small person may crawl. Exteriorly this opens into a vertical flue which was broken down; inside it ends bluntly at the fire-hole. About midway of its length there extends from it a lateral passageway, slightly curved, forming a well-worn doorway. This curved passage opens through the kiva floor by a manhole. The walls of these passages are constructed of good masonry. Their function is unknown, but as most structures connected with kivas are ceremonial, this may provisionally be called a ceremonial opening.
