t far from the promontory at the
lower level of the line, which conducts to a ledge running along in
front of the caves about 150 feet above the bed of the stream. Roughly
speaking, this ledge is about 100 feet below the summit of the cliff.
It was impossible to reach several of the rooms, and it is probable
that when the caves were inhabited access to any one of them was even
more difficult than at present.

Judging from the number of rooms, the cliffs on the left bank of the
Verde must have had a considerable population when inhabited. These
caverns, no doubt, swarmed with human beings, and their inaccessible
position furnished the inhabitants with a safe refuge from enemies, or
an advantageous outlook or observation shelter for their fields on the
opposite side of the stream. The soft rock of which the mesa is formed
is easily worked, and there are abundant evidences, from the marks of
tools employed, that the greater part of each cave was pecked out by
hand. Fragments of wood were very rarely seen in these cliff dugouts;
and although there is much adobe plastering, only in a few instances
were the mouths of the caves walled or a doorway of usual shape
present. The last room at the southern end, near the promontory at the
right of the entrance to a side canyon, has walls in front resembling
those of true cliff houses and pueblos in the Red-rock country farther
northward, as will be shown in subsequent pages.

This group of cavate dwellings, while a good example of the cavern
type of ruins, is so closely associated, both in geographical position
and in archeological remains, with other types in Verde valley, that
we are justified in referring them to one and the same people. The
number of these troglodytic dwelling places on the Verde is very
large; indeed the mesas may be said to be fairly honeycombed with
subterranean habitations. Confined as a general thing to the softer
strata of rock, which from its character was readily excavated, they
lie side by side at the same general level, and are entered from a
projecting ledge, formed by the top of the talus which follows the
level of their entrances.

This ledge is easily accessible in certain places from the river bed,
where stones have fallen to the base of the cliff; but at most points
no approach is possible, and in their impregnable position the
inhabitants could easily defend themselves from hosti
