Nonstructure 102, midden
About this Nonstructure
General Location
West central portion of the site.
Specific Location
Nonstructure 102 is in the western portion of Structure 110's midden.
Selection Criteria
Nonstructure 102 was used to document midden deposits affected by modern chaining and burning activities.
Use
Nonstructure 102 is a deflated midden deposit affected by chaining and burning activities. The sediments of Nonstructure 102 have eroded away, but the artifacts remained in post-occupational deposits.
Abandonment
Nonstructure 102 was no longer used after Structure 110 was decommissioned.
Postabandonment Process
Nonstructure 102 was deposited through natural processes (wind and water), chaining, and burning activities.

Excavation Details for Excavation Units
In order by excavation unit number.
Excavation Unit
8
Location
1-x-1 meter grid unit 1418N 201E.
Southwest quarter of the site.
Located near the west border of the midden (Nonstructure 102), approximately 17 m southwest of Structure 110.
Selection Criteria
Random. Eighteenth 1-x1-m unit selected for excavation in Nonstructure 101. Note that the Study Unit for this Excavation Unit was later changed to Nonstructure 102 due to the presence of modern chaining disturbance.
Excavation Strategy
Natural strata.
Unit Ends at
Undisturbed native sediment. Excavation was terminated at approximately 110.63 m. A 20 cm x 20 cm window was dug into the northeast corner of the unit to confirm sterility; the bottom of this window was at an elevation of 110.53 m.

Location
2-x-2 meter grid unit 1429N 222E.
Northeast quarter of the site.
Located in the northeast quarter of Nonstructure 101, approximately 11 m southeast of Structure 110.
Selection Criteria
Judgmental. This excavation unit was selected in order to investigate several upright sandstone slabs that were visible on the modern ground surface. These slabs likely formed part of a check dam and were recorded as Feature 1.
