About a quarter of a mile west of the main ruin there is another small but well-preserved cluster of rooms. It occupies the narrow

ridge of a hill some 200 feet above the river. On the west and south, the hill descends abruptly to the river; on the southeast and east it slopes sharply down to a broad valley on the level of the mesa bench before mentioned, but the valley is cut by a narrow and deep canyon marking the east side of the hill. This cluster is shown on the ground plan, plate XVII, though not in its proper position. Northeast of this cluster and perhaps 200 yards distant there are traces of other rooms, but they are so faint that no plan can be made out. As shown on the sketch map, [figure 284], the hill is a long narrow one, and its western side falls rapidly to a large triangular area of flat bottom land lying between it and Beaver creek, which it overlooks, as well as a large area of the valley up the river and all the fine bottom lands north and east of Verde and on the northwestern side of Beaver creek. As regards outlook, and also as regards security and facility of defense, the site of the small cluster is far superior to that of the main cluster of rooms.

Plate XIX. Southern Part of Ruins Opposite Verde.

About a quarter of a mile south and east of the main ruin, on the opposite side of the little valley before mentioned, a mesa bench similar to the one last described occurs; and on a point of this, extending almost to the river bank, there are traces, now nearly obliterated, of a small cluster of rooms. A short distance east of this point there is a large rounded knoll, with a peculiar terrace-like bench at about half its height. The entire summit of this knoll was occupied by rooms, of which the walls are much broken and none remain standing. This knoll, with the ruins on its summit, is shown in plate XIX, which also gives a general view from the north of the small cluster southeast of the main ruin. The character of the valley of the Verde at this point is also shown. The sketch map, [figure 284], shows the location of these ruins in reference to others of the group.

The main cluster, that portion occupying the crown or summit of the butte before described, exhibits at the present time some fifty rooms in the ground plan, but there were at one time a larger number than this; and there is no doubt that rooms extended down the slopes of the hill southward and southwestward. The plan of this main cluster is peculiar; it differs from all the smaller surrounding clusters. It tells the story of a long occupancy by a people who increased largely in numbers, but who, owing to their hostile environment, could not increase the space occupied by them in proportion to their numbers. It will be noticed that while the wall lines are remarkably irregular in arrangement they are more often continuous than otherwise, more frequently continuous, in fact, than the lines of some of the smaller villages before described. The rooms are remarkably small, 10 feet square being a not unusual measurement, and built so closely together as to leave no space for interior courts. The typical rooms in the ruins of this region are oblong, generally about twice as long as broad, measuring approximately 20 by 10 feet.

In the ruin under discussion it seems that each of these oblong rooms was divided by a transverse partition into two smaller rooms, although the oblong form is also common. This is noticeable in the southwestern corner and on the eastern side of the main cluster, in the southwestern corner and on the northern end of the cluster adjoining on the north, and in all the smaller clusters. It is probable that the western central part of the main cluster was the first portion of the group of structures built, and that subsequently as the demand for accommodation increased, owing to increase of population, the rooms on the eastern and southern sides of the main cluster were added, while the rooms of the older portion were divided.

There is no evidence that any portion of this cluster attained a greater height than two stories, and only a small number of rooms reached that height. The small cluster adjoining on the north, and those on the southeast, southwest, and west, were built later and belong to the last period of the occupancy of the group. The builders exhibited a decided predilection for a flat site, as an examination of the sites of the various room clusters in the ground plan ([plate XVII]) will show, and when the sight of the main cluster became so crowded that additional rooms could be added only by building them on the sloping hillside, recourse was had to other sites. This tendency is also exhibited in the cluster adjoining the main cluster on the north, which was probably the second in point of age. The northern end of this small group of rooms terminates at the foot of the hill which rises northeastward, while a series of wall lines extends eastward at an angle with the lines of the cluster, but along the curve of the hillside.
