Nonstructure 203, extramural surface
About this Nonstructure
General Location
South part of the site.
Specific Location
Along the north wall of the roomblock in Architectural Block 200.
Selection Criteria
This surface was encountered during excavations to expose the north wall of the adjacent roomblock.
Use
Outdoor use surface associated with the occupation of Architectural Block 200.
Abandonment
This surface was no longer used as a surface after refuse accumulated on it.
Postabandonment Process
Not affected by postabandonment processes, because it was buried.
Dating of Construction
This outdoor use surface was not constructed, but was used after the adjacent roomblock was constructed, and after Structure 204 (directly beneath this surface) filled with collapsed roofing material and other sediment. The fill of Structure 204 contains Mesa Verde Black-on-white sherds, which indicates that Nonstructure 203 was used sometime after A.D. 1180.
Dating of Abandonment
The association of Mesa Verde Black-on-white sherds with this surface and the presence of this pottery type in the 1.0 m of fill below it indicates that the surface was abandoned sometime after A.D. 1180.
Date Range
