About this Nonstructure

Has Surface
No Masonry

General Location

Central portion of site.

Specific Location

North-central portion of Block 100; below southeast portion of Structure 103.

Selection Criteria

Encountered surface and features of Nonstructure 120 below Structure 103.


This surface represents an extramural use area from which two pit features (Feature 1 and Feature 2) were excavated. Structure 103 was constructed above this surface after the pits were no longer used.


This surface was probably not used after the middle Pueblo II period.

Postabandonment Process

Structure 103 was constructed above this surface after the pits were no longer used.

Dating of Construction

Based on a Chapin Black-on-white sherd, this surface is inferred to have been used during the Pueblo I period. This surface exists below Structure 103, which was constructed in the Pueblo II period. It is possible that this surface was also used during the Pueblo II period prior to the construction of Structure 103.

Dating of Remodeling

None evident.

Dating of Abandonment
