Arbitrary Unit 103, not further specified
About this Nonstructure
General Location
Central portion of the site.
Specific Location
Arbitrary Unit 103 was only identified above the collapse and the refilled the great kiva deposits.
Selection Criteria
Selected to excavate the northwest and southeast quarters of the great kiva.
Use
Natural wind blown deposit.
Abandonment
Not applicable.
Postabandonment Process
Not applicable.
Dating of Construction
Based on the pottery in underlying sediments and the lack of pottery in Arbitrary Unit 103, this sediment was likely deposited after the Ancestral Pueblo depopulation of the Mesa Verde region between A.D. 1300 and 1700.
Dating of Remodeling
Not applicable.
Dating of Abandonment
Not applicable.
