The towers in Holly Canyon (fig. 11) are in about the same condition
of preservation as those in Square Tower Canyon. They cluster about
the head of a small canyon (pl. 18, _a_) and may be approached on foot
along the mesa above Keeley Camp, about a mile distant. Two of the
Holly ruins belong to the tower type and were built on fallen bowlders.
One of these has two rooms on the ground floor. (Pls. 19, _a_, _b_; 20,
_a_, _c_.)
