About 14 miles north of the mouth of Fossil creek, on the eastern side of the river, there is another ruin somewhat resembling the last described. A large red rock rises at the intersection of two washes, about a mile back from the river, and on a bench near the summit are the remains of walls. These are illustrated in plate XXIII. In general appearance and in character of site this ruin strongly resembles a type found in the San Juan region. There seem to have been only a few rooms on the top of the rock, and the prominent wall seen in the illustration was probably a retaining or filling wall in a cleft of the rock. Such walls are now used among the Pueblos for the sides of trails, etc. It is probable that at one time there were a considerable number of rooms on the rock; the debris on the ground at the base of the rock on the western side, shown in the illustration, is rather scanty; on the opposite or eastern side there is more, and it is not improbable there were rooms on the ground here. It is likely that access was from this side. It should be noted that this ruin, which is of a type known as “fortress” by some writers, is so placed as to command an extensive outlook over the large valley below and over the two small valleys above, as well as the considerable area of flat or bottom land formed by the junction of the small valleys. It is a type of a subordinate agricultural settlement, and had the defensive motive been entirely absent from the minds of the builders of this village it would undoubtedly have been located just where it now is, as this is the best site for an agricultural settlement for some distance up and down the river. [Illustration: Figure 287. Sketch map of ruins on pinnacle 7 miles north of Fossil creek.] [Illustration: Figure 288. Remains of small rooms 7 miles north of Fossil creek.] Remains of walls somewhat similar to these last described occur on a butte or pinnacle on the eastern side of the river and about 7 miles north of the mouth of Fossil creek. From the south this pinnacle is a most conspicuous landmark, rising as it does some 2,500 feet above the river within a distance of a quarter of a mile. The upper 50 feet of the eminence consists of bare red rock split into sharp points and little pinnacles, as shown in figure 287, which represents only the upper portion of the butte. The heavy black lines on the sketch map are walls. Some of these were doubtless mere retaining walls, but others are still standing to a considerable height, and there is yet much débris on the slope of the rock forming the eastern side of the butte near its top. It is doubtful whether these rooms were ever used for habitations, and more probable that they were used as a shrine or for some analogous purpose. [Illustration: Plate XXVI.
