Structure 13-S, aboveground kiva

CONSTRUCTION

Method and Sequence

Kiva is believed to have been built from the ground up because bedrock is not far below modern ground surface. The east wall of a multistory room unit (Structures 11-S and 21-S) appears to have been used as an enclosing wall on the west side of the kiva, considering that the kiva was built up against the wall. This probable enclosing wall may curve to the east at the edge of the cliff and run south of the kiva to the east cliff face. A portion of a masonry wall that may be part of this wall is visible southeast of the kiva, as is another wall that runs perpendicular to the south wall and rests east of the kiva. Taken together, these wall sections suggest that the kiva was enclosed on its west, south, and east sides. The only exposed architecture from the kiva itself is a northwest section of the upper lining wall, a pilaster (Feature 1), and a roofed opening (Feature 2) adjacent to the pilaster. Based on its architecture, it is clear that this kiva was not constructed in a typical manner. A bench was presumably built and pilasters were contructed on top of the bench. Beams were then laid that spanned from one pilaster to another. Next, the upper lining wall was constructed on top of the pilasters and beams. This created large openings below the wall and between the pilasters. Finally, a roof is believed to have built on top of the upper lining wall.

Roof Description

The upper lining wall, not the pilasters, is believed to have supported the roof. See construction method and sequence comments above.
