[Illustration: FIG. 13.—Ground plan of towers on Long Mesa.]
On the flat top of a long and narrow mesa (pl. 9, _a_, _b_) rising
about 200 feet from the middle of Hill Creek Canyon a few miles above
Taylor’s ranch, there is a cluster of three circular ruins, whose
walls are composed of well constructed masonry, now much dilapidated.
The surface of this plateau, near the end looking down the canyon, is
partitioned off from the remainder by a low transverse wall, extending
from one side to the other. This wall was built advantageously for
defense and apparently designed to prevent passage of foes from the
upper end of the plateau into the area where the circular rooms are
situated. About midway in its length it has a passageway, the jambs of
which are still visible. Three circular ruins (fig. 13) make up the
cluster on the lower end of the mesa, each averaging about 15 feet in
diameter, all constructed of low walls of stones dressed into proper
shape. These buildings are not connected but separated by intervals.
The tops of the walls for several feet have fallen, exposing interiors
which are almost completely filled with stones and rubble.
