Nonstructure 1226, extramural surface

About this Nonstructure

Has Surface
No Masonry

General Location

At the north edge of the great tower complex.

Specific Location

8 m northeast of Structure 1210; above extramural surface Nonstructure 1223.

Selection Criteria

This surface was defined during excavations to expose and document masonry wall (possible water-control feature associated with the great tower complex).


Use of this surface is not clear from the small amount of surface exposed, but was probably related to water-procurement activities associated with Nonstructure 1223, Feature 1 (wall:other), which is inferred to have been a dam.


Abandoned as a result of roomblock abandonment.

Postabandonment Process

Surface was buried by stones that collapsed off of the adjacent wall and sediment that was deposited naturally.

Dating of Construction

This surface is above, and so postdates, the surface associated with the construction of the adjacent Nonstructure 1223, Feature 1 (wall:other). This wall is of pecked-block masonry style, and is either double-stone or double-stone-with-core in cross-section. These masonry styles indicate construction in the Pueblo III period (A.D. 1150-1300).

Dating of Abandonment

Abandoned when the adjacent roomblock was abandoned.

Date Range

6 (A.D. 1225–1300)
