About this Nonstructure
General Location
Southwest part of the site.
Specific Location
At the north edge of the roomblock in Architectural Block 2500.
Selection Criteria
Surface was encountered during excavations to expose a segment of the north wall of the adjacent roomblock.
Use
Outdoor use surface associated with construction and occupation of Architectural Block 2500.
Abandonment
Abandoned when occupation of this area ended.
Postabandonment Process
Surface was covered by cultural materials associated with occupation of roomblock, alluvial deposits, then wall fall and aeolian/alluvial sediments.
Dating of Construction
This surface was not constructed, but was prehistoric ground surface when the adjacent roomblock was constructed. The pecked-block masonry style of the north wall of that structure indicates construction during the Pueblo III period (A.D. 1150-1300).
Dating of Abandonment
The presence of Pueblo III White Painted pottery on this surface indicates that the surface was abandoned sometime after A.D. 1100, and association with the adjacent roomblock indicates the surface was abandoned during the Pueblo III period (1150-1300).
Date Range
5 (A.D. 1180–1260)
