About this Nonstructure
General Location
Southwest portion of the site.
Specific Location
Nonstructure 225 is adjacent to and overlays Structure 205-226.
Selection Criteria
Excavation units were used to investigate a remote-sensing anomaly. First, the outline of the pithouse was exposed in 2-x-2-m units. Second, the north half of the structure chamber's were excavated in quadrants.
Use
Nonstructure 225 is a thin Basketmaker III era midden deposited above and around Pithouse 205-226.
Abandonment
Its presence suggests that occupation continued at the site after the Pithouse 205-226 was abandoned.
Postabandonment Process
Arbitrary 202 was deposited through natural processes (wind and water) over Nonstructure 225.
Dating of Midden
Basketmaker III period A.D. 600 to 725.
Date Range
3 (A.D. 660–725)
