Figure 1 is a ground plan of a small ruin located in Del Muerto, on the bottom lands near its mouth. No standing walls now remain, but there is no doubt that the village at one time covered much more ground than that shown on the plan. There are now remains of sixteen rooms on the ground, in addition to two kivas. There is a shallow alcove in the cliff at the ground level, and the overhanging cliff gave the village some protection overhead. Plate XLV shows another example in Del Muerto, the largest in that canyon. The walls are still standing to a height of three stories in one place, and the masonry is of high class. The back cliff has not entered into the plan here to the same extent that it generally does. Figure 2, a ground plan, exhibits only that portion of the area of the ruin on which walls are still standing. It shows about 20 rooms on the ground, exclusive of three or perhaps four kivas. The rooms are small as a rule, rectangular, and arranged with a more than ordinary degree of regularity. One room still carries its roof intact, as shown on the plan. In the center of the ruin are the remains of a very large kiva, over 36 feet in diameter. It is now so much broken down that but little can be inferred as to its former condition, except that there was probably no interior bench, as no remains of such a structure can now be distinguished. The size of this kiva is exceptional, and it is very probable that it was never roofed. The structures within the kiva, shown on the ground plan, are Navaho burial cists. West of the large kiva there were two others, less than 20 feet in diameter. One of these was circular; the other was irregular in shape, perhaps more nearly approaching an oval form. At no fewer than five places within the ruin there are comparatively recent Navaho burials.
