At the northeastern corner of the main room there is a wide opening leading into a room measuring 8 by 7 feet, with a floor raised 2 feet above that of the principal apartment. The roof of this chamber is but 4½ feet above the floor. Almost the whole eastern side of this room is occupied by a wide opening leading into another room of approximately the same size and shape. The roof of this room is only 3 feet 10 inches above the floor, and the floor is raised 6 inches above that on the west. In the northeastern corner there is a short narrow passageway leading into a small circular room, the fourth of the series, having a diameter of 4 feet. The roof of this apartment is only 3 feet above the floor. [Illustration: Plate XXXV. OLD IRRIGATING DITCH, SHOWING CUT THROUGH LOW RIDGE.] In the southeastern corner of the main room there is a narrow passageway leading into a circular chamber about 8 feet in diameter. This chamber is connected with the second room of the series described by a passageway about 2 feet long, which opens into the southeastern corner of that room. This passageway, at its northern end, is 1½ feet below the room into which it opens. One of the most noticeable features about this group of rooms is the entire absence of the little nooks and pockets in the wall which are characteristic of these lodges, and which are very numerous in all the principal groups, noticeably in the group next described. [Illustration: Figure 298. Plan of cavate lodges, group _C_.] At the point marked _C_ on the map there is an elaborate group of chambers, consisting of two groups joined together and comprising altogether eight rooms. This is shown in plan in figure 298. The rock composing the front of the main room of the southern group has recently fallen, making a pile of debris about 4 feet high. The room originally measured about 12 by 22 feet. Its eastern side is occupied by a passageway leading into an adjoining chamber and by two shallow, roughly semicircular coves, apparently the remains of former small rooms. Along the northern wall of the room there are two little nooks at the floor level, and along the southern wall there are four, one of them (shown on the plan) being dug out like a pit. The roof of the room was about 6 feet above the floor.
