General description
Masonry, retaining wall.
Use history
Retaining wall for multiple buildings and their associated open space, including Structure 5; built along a natural bedrock ledge where the area directly behind the ledge is flat and the area downslope is quite steep; wall was not built exclusively as a kiva retaining wall for Structure 5, although it appears to have been constructed around the same time as the construction of Structure 5.
Associated features
None.
Excavation procedure
Exposed during excavation and documented.
Portion excavated
Portion within Segment 1 and immediately north of excavation unit.
Horizontal location
Forms the north boundary of Segment 1; immediately south of Structure 5, a kiva.
Vertical location
Rests on a bedrock shelf, which is defined as Surface 2.
Construction
Wall was built on a natural bedrock ledge; the area behind the wall and ledge is flat and the area downslope is quite steep; Morrison formation materials, that may be spoil dirt from the construction of a nearby kiva (Structure 5), were used to fill in a concavity in the bedrock ledge; wall is uncoursed and was constructed using large, unshaped tabular stones, a fine-grained mortar, and a few chinking stones; see Masonry form for architectural details.
