Nonstructure 1219, extramural surface

About this Nonstructure

Has Surface
No Masonry

General Location

In the great tower complex.

Specific Location

Adjacent to the west wall of the bi-wall structure.

Selection Criteria

Surface was encountered during excavations to expose the outside face of the bi-wall structure and document the outside surface associated with it.


Probably used for a variety of outdoor activities by the occupants of bi-wall Structures 1214 and 1222 adjacent to the west. The mano and the small pit feature are probably remnants of some of these activities. Other artifacts on this surface were probably incidental refuse; some refuse also accumulated in the sediment above this surface (possibly tossed out of windows in Structure 1214 or 1222).


Abandoned as a result of the abandonment of the adjacent roomblock.

Postabandonment Process

Wall stones from the bi-wall structure collapsed onto the surface.

Dating of Construction

Surface was not constructed.

Dating of Abandonment

The presence of Mesa Verde Black-on-white pottery indicates that this surface was used after A.D. 1180.

Date Range

6 (A.D. 1225–1300)
