Owing to its situation this room was one of the most desirable in the whole group. The prevailing south wind blows through it at all times, and this is doubtless the reason that it was so much filled up with sand. In the center of the room the roof has fallen at a comparatively recent date from an area about 10 by 7 feet, in slabs about an inch thick, for the fragments were within 6 inches of the top of the debris. The walls are smoke-blackened to a very slight extent compared with the large room south of it. At the northeastern and southwestern corners there are two small pockets, opening on the floor level but sunk below it, which seem to have been designed to contain water. That in the southwest corner is the larger; it is illustrated in the section, figure 293. As shown in the section and on the plan (figure 291), a low wall composed of adobe mortar and broken rock was built across the opening on the edge of the floor, perhaps to increase its capacity. This cavity would hold 15 to 20 gallons of water, a sufficient amount to supply the needs of an ordinary Indian family for three weeks or a mouth. The pocket in the northeastern corner of the room is not quite so large as the one described, and its front is not walled. [Illustration: Plate XXXIII. BOWLDER-MARKED SITE.] West of the main room there is a storage room, nearly circular in shape, with a diameter of about 6 feet and with a floor raised about 2 feet above that of the main room. Its roof is but 3 feet above the floor, and across its western end is a low bench a couple of inches above the floor. In the northeastern corner there is a shallow cove, also raised slightly above the main floor and connecting by a narrow opening with the outer vestibule-like rooms on the north. These northern rooms of the lodge seem to be simply enlargements of the passageway. The northern opening is a window rather than a door as it is about 10 feet above the ground and therefore could be entered only by a ladder. The opening is cut in the back of a cove in the cliff, and is 6 feet from the northern end of the main room. At half its length it has been enlarged on both sides by the excavation of niches or coves about 4 feet deep but only 2½ feet high. These coves could be used only for storage on a small scale. [Illustration: Figure 294. Plan of cavate lodges, group _A_.] In the southeastern corner of the main room there is another opening leading into a low-roofed storage cist, approximating 4 feet in diameter, and this cist was in turn connected with the middle one of the three rooms first described. This opening, at the time the room was examined, was so carefully sealed and plastered that it was scarcely perceptible.
