Several broken-down walls, some of which are over 6 feet high, situated
east of Ruin A, appear to belong to a pueblo of considerable size (fig.
11, _E_, _F_), but the large foundation rock on which it is situated
has settled, its top having separated from the edge of the canyon, so
that the corner of the building (_F_) is out of plumb. The walls on the
adjoining cliff are also much broken down, although several sections
of them rise a few feet above the general surface. The cause of this
change in level of the base may have been an earthquake or the settling
or sliding of the bowlder on the talus down the hill. The united
building appears to have been a pueblo of rectangular form. Its walls
are so broken down that it was not possible to determine its exact
dimensions.
