Nonstructure 103, not further specified
About this Nonstructure
General Location
Nonstructure 103 is located in the central portion of the site.
Specific Location
Nonstructure 103 is below Arbitrary 102 and above Structure 108.
Selection Criteria
Nonstructure 103 defines upper construction fill and some secondary deposits, over Structure 108.
Use
Nonstructure 103 is a reddish-brown silty clay with charcoal, calcium carbonate, and adobe flecks. A low density of relatively small sandstone chunks and blocks were observed. Nonstructure 103 is upper construction fill mixed with some secondary deposits, over Structure 108.
Abandonment
Nonstructure 103 was deposited shortly after Structure 108 was decommissioned. This interpretation is based on the fact that there was a lack of laminates and wind/water-borne sediments between the deposits of Structure 108 and Nonstructure 103.
Postabandonment Process
Nonstructure 103 was likely deposited by both natural and cultural forces. Structure 108's collapse created a depression in the ground. Because Nonstructure 103 contained artifacts contemporaneous with those found in Structure 108, it is conceivable that the inhabitants of Structure 108 filled part of the depression with construction deposits and a small amount of secondary refuse. It is also possible that Nonstructure 103 was deposited, in part, by wind/water.

Excavation Details for Excavation Units
In order by excavation unit number.
Excavation Unit
12
Location
3-x-2 meter grid unit 889N 2194.25E.
Central portion of the site.
This excavation unit is southeast of Arbitrary 105, and west-northwest of Nonstructure 106.
Selection Criteria
Judgmental. This excavation unit was used to investigate the nature of an electrical resistivity anomaly.
Excavation Strategy
Strata subdivided into arbitrary levels. Natural strata were subdivided into 20 cm arbitrary levels. Once the elevation of the floor was determined, excavation terminated 5 cm above the floor, regardless of whether 25 cm in depth had been attained.
Unit Ends at
Structure floor. Excavation terminated at approximately 81.40 meters below datum. The floor of Structure 108, in this excavation unit, had likely eroded away revealing the underlying natural, undisturbed, calicium carbonate deposit.

Location
Segment 1 N E.
(Segment 1 is 10.5 meters long, 70 centimeters wide.)
Segment 1 is located in the central portion of the site.
This excavation unit is southeast of Arbitrary 105, and west-northwest of Nonstructure 106.
Selection Criteria
Judgmental. Segment 1 was used to investigate the nature of an electrical resistivity anomaly.
Excavation Strategy
Other. Overburden was removed using a backhoe, until rock was encountered and it became clear we were in a structure. At this point, natural strata were subdivided into 25 centimeter arbitrary levels.
Unit Ends at
Structure floor. Excavation terminated at approximately 81.70 meters below datum. The floor in this excavation unit likely eroded away, revealing the underlying, natural, undisturbed, calcium carbonate deposit.

Central portion of the site.
This excavation unit is southeast of Arbitrary 105, and west-northwest of Nonstructure 106.
Selection Criteria
Judgmental. This 1-x-2-m unit was used to investigate the nature of an electrical resistivity anomaly.
Excavation Strategy
Strata subdivided into arbitrary levels. Natural strata weres subdivided into 25 cm levels.
Unit Ends at
Structure floor. Excavation terminated at approximately 81.42 meters below datum. The floor revealed in this excavation unit was a red plaster, with areas of burning from the roof falling on it. In places, the plaster had eroded away, revealing the undisturbed, natural,
