Cliff outlooks are often found on sites whose restricted areas preclude all possibility that they formed parts of larger settlements since obliterated. The ruin just described is an example. Another instance which occurs in Del Muerto is shown in figure 58. Here a deep cleft in the rock was partly occupied by two or three rooms. There was room for more, but apparently no more were built. There was not room, however, for even a small village. There are several other examples in the canyon almost identical with these, but this type is not nearly so abundant as the succeeding. Figure 59 is a plan of a ruin near the mouth of Del Muerto. It was a single room, situated on a ledge perhaps 30 or 40 feet above the bottom land which it overlooked and of easy access. This is the most common type of outlook or cliff ruin, and it might almost be said that they number hundreds, sometimes consisting of one room alone, sometimes of two or even three The general appearance of these outlooks is shown in figure 60, which shows an example containing three rooms. [Illustration: Fig. 60--Three-room outlook in Canyon del Muerto.] [Illustration: Fig. 61--Plan of a two-room outlook.] Figure 61 is a ground plan of an example containing two rooms, which occurs below the large ruin described before (No. 31, page 119), and figure 62 shows an example with one room, obscured and built over with Navaho cists. This site is located in the upper part of the canyon, on top of the talus, about 100 feet above the stream, and commands an outlook over several areas of bottom land on both sides. The walls are built about 10 feet high, and are composed of medium-size stones laid in courses and carefully chinked with small spalls. The southwestern corner of the room is broken down, but the eastern wall is still standing, and shows a well-finished opening on that side. There are several Navaho burial cists on this site.
