Arbitrary Unit 107, noncultural
About this Nonstructure
General Location
Arbitrary 107 is located in all of Block 100.
Specific Location
Arbitrary 107 underlies all study units associated with the Dry Ridge site.
Selection Criteria
Arbitrary 107 defines the pre-occupational, undisturbed, native sediment in Block 100. It was identified in the randomly-tested midden deposits, and in the judgementally-tested structure and rubble-pile.
Use
Arbitrary 107 is a reddish loess, and is the undisturbed, pre-occupational, native sediment in Block 100. No artifacts were identifed and/or observed in this deposit, supporting the interpretation that this is a pre-occupational deposit.
Abandonment
No artifacts were identified as lying on the surface of Arbitrary 107, likely due to modern plowing activity that clipped the upper few centimeters of this deposit.
Postabandonment Process
During occupation of the site, the midden, Nonstructure 106, was deposited over Arbitrary 107. Structure 108 was dug into Nonstructure 106. Modern plowing also affected the integrity of this deposit. All these variables contributed to Arbitrary 107's post-occupational processes.
