Figure 48 is a ground plan of a ruin which occurs at the point marked 46 on the map. It is situated in a cove in the rock at the top of the talus, 300 or 400 feet above the bottom, and immediately above the rectangular single room described and illustrated on page 151. It commands an extensive outlook over the bottom lands on both sides of the canyon and above. The cove is about 40 feet deep, and, though so high up, has been used as a sheep close, and doubtless some of the walls have been covered up. Four rooms are still standing in two little clusters of two rooms each. The walls of the rooms on the west are composed of large stones laid in plenty of mud mortar and plastered inside and out; those of the eastern portion were built of small stones, chinked but not plastered. One of the rooms is blackened by smoke in the corner only, as though there had been some chimney structure here, which subsequently had fallen away. The cliff walls back of the eastern part are heavily smoke-blackened; back of the western portion there are no stains. There is now no trace of a circular kiva, but there is a heavy deposit of sheep dung on the ground which might cover up such traces if they existed. This site commands one of the best outlooks in the canyon, but access, while not very difficult, is inconvenient on account of the great height above the bottom. [Illustration: Fig. 49--Plan of cliff room with partitions.] Figure 49 shows a common type of ruin in this class. The original structure appears to have contained one or two good rooms, which by subsequent additions have been divided into several. These later additions may have been made by the Navaho, who used the building material on the ground; at any rate the structure is now merely a cluster of storage cists. [Illustration: Fig. 50--Plan of a large cliff outlook in Canyon del Muerto.] One of the most extensive ruins of the cliff-outlook type situated in Canyon del Muerto is shown in figure 50. The plan shows at least eight rooms stretched along the cliff at the top of the talus. Figure 51 shows five rooms arranged in a cluster. One of these is still complete, the walls extending to the overhanging rock above which formed the roof. It will be noticed that the front room was set back far enough to allow access to the central room through a doorway in the corner. This was a convenience, rather than a necessity, for many of the rooms in ruins of this class were entered only through other rooms or through the roof, and a direct opening to the outer air was not considered a necessity; probably because these rooms in the cliff, which have been termed outlooks, were not in any sense watch towers, but rather places of abode during the harvest season, where the workers in the field lived when not actually employed in labor, and where the fields tinder cultivation could always be kept in view--an arrangement quite as necessary and quite as extensively practiced now as it was formerly.
