The ruin formerly called Willow House, but now known as Oak Tree
House, lies on the north side of Fewkes Canyon, in a symmetrical cave
and has an upper and a lower part. The two noteworthy features of Oak
Tree House are the kivas and the remnant of the wall of a circular
room made of sticks plastered with adobe but destitute of stone
masonry.
Oak Tree House has seven kivas and may be called a large cliff
dwelling. One of the kivas has a semicircular ground plan with a
rectangular room on the straight side. There are no pilasters or
banquettes in this kiva. The floor of another kiva was almost wholly
occupied by a series of grinding bins, indicating a secondary use. The
excavation work on Oak Tree House has not yet been completed, but a
small collection of specimens at one end of the ruin shows the nature
of the objects thus far found.
