Nonstructure 251, extramural surface

About this Nonstructure

General Location

Central portion of site.

Specific Location

West-central portion of Block 200. South of Structures 222 and 223.

Selection Criteria

Placed south of Structures 222 and 223 to sample associated midden deposits; exposed Nonstructure 251.

Use

This is an extramural surface on which a masonry wall, Feature 1 (wall, other) was constructed. This wall was truncated by plowing, therefore it was unclear if this was once part of a structure.

Abandonment

This surface was no longer used after the late Pueblo II period.

Postabandonment Process

Secondary refuse (Nonstructure 238) was deposited above this surface. Natural sediments accumulated above the refuse; the upper deposits were disturbed by plowing.

Dating of Construction

Secondary refuse, Nonstructure 238, was deposited above this surface and dates from the late Pueblo II period. Therefore, this surface must date from the Pueblo II period.

Dating of Remodeling

None evident.
