Ruin B
Fig. 12.—Ground plan of ruin B.
Ruin B (pls. [7], [8], b) is a better preserved example of the tower type and is on a ridge considerably lower than that on which ruin A stands extending at right angles. It occupies a narrow space from the rim of Hill Canyon on one side to a rim of a tributary canyon, blocking the passageway along the surface of the ridge to its point. This structure ([fig. 12]) would appear to be structurally not unlike ruin A, but with the wall smaller. There is a raised bench on the south side, the tower itself being a semi-circular chamber annexed to the north side, which extends from one canyon rim to another. The breadth of this semi-circular room is 10 feet. The longest dimension is 31 feet and the average height of its wall is 4 feet. The top of the wall, throughout, is unevenly broken down, the part adjoining the bench being the best preserved. The structure suggests a fort, for it would not be possible to pass between this obstructing ruin without entering it through a circular doorway, the walls of which still stand on the east side. There is no passage between the wall and the mesa edge.
