About 150 yards southeast from the church, and on the edge of the low
mesa upon which the ruin stands, has been constructed a reservoir of
large size which furnished the pueblo with a reserve water supply. The
ordinary supply was probably derived from the valley below, where water
is found at no great distance from the pueblo. Springs may also have
formerly existed near the village, but this reservoir, located where the
drainage of a large area discharges, must have materially increased the
water supply. The basin or depression is about 110 feet in diameter and
its present depth in the center is about 4 feet; but it has undoubtedly
been filled in by sediment since its abandonment. More than half of its
circumference was originally walled in, but at the present time the old
masonry is indicated only by an interrupted row of large foundation
stones and fallen masonry. Some large stones, apparently undisturbed
portions of the mesa edge, have been incorporated into the inclosing
masonry. The Indians stated that originally the bottom of this basin was
lined with stones, but these statements could not be verified. Without
excavation on the upper side, the basin faded imperceptibly into the
rising ground of the surrounding drainage. Other examples of these basin
reservoirs are met with in this region.

CHALOWE.

About 15 deg. north of west from Hawikuh, and distant 11/2 miles from it,
begins the series of ruins called Chalowe. They are located on two low
elevations or foothills extending in a southwestern direction from the
group of hills, upon whose eastern extremity Hawikuh is built. The
southernmost of the series covers a roughly circular area about 40 feet
in diameter. Another cluster, measuring about 30 feet by 20, lies
immediately north of it, with an intervening depression of a foot or so.
About 475 feet northwest occurs a group of three rooms situated on a
slight rise. A little east of north and a half a mile distant from the
latter is a small hill, upon which is located a cluster of about the
same form and dimensions as the one first described. Several more
vaguely defined clusters are traceable near this last one, but they are
all of small dimensions.

This widely scattered series of dwelling clusters, according to the
traditional a
