Hypotheses

• Trade or migration

• Determine regions of interaction

• Phase

• Purpose of site

Page 3: The Gehring Site: An Analysis of a Middle Woodland Lithic Assemblage in the American Bottom

Middle Woodland• Time frame

– 150 BC to AD 350

• “People of colors and glitter” • (Fortier 2008)

– Variety of colors– Variety of chert types

Fortier 2008

Movement Patterns

• Trade, migration, direct procurement

• Equifinality

• Literature unclear

Feature Results

Local chert types-Burlington-Chouteau-Salem-Glacial till

Page 10: The Gehring Site: An Analysis of a Middle Woodland Lithic Assemblage in the American Bottom

Non-local chert types– Grimes Hill– Cobden/Dongola– Kaolin– Ste. Genevieve– Mill Creek

Page 11: The Gehring Site: An Analysis of a Middle Woodland Lithic Assemblage in the American Bottom

• Debitage– Core reduction

• 33 flakes– 64% Burlington

– Bifacial reduction• 51 flakes

– 53% Burlington

– Shatter• 51 flakes

– 69% Burlington

Page 12: The Gehring Site: An Analysis of a Middle Woodland Lithic Assemblage in the American Bottom

Blades-58% of tool assemblage-Characteristics

-Parallel sides-Ridges

-Technology

Flake Tools-15% of tool assemblage-Expedient -Re-sharpening

Page 13: The Gehring Site: An Analysis of a Middle Woodland Lithic Assemblage in the American Bottom

Results

• Hoe Flake– 15% of tool assemblage– Sharpening hoes– Polish

Scrapers-4% of tool assemblage-Retouching-Burlington

-Norton reworked into scraper-Glacial Till

-Exhausted humpback scraper-Ste. Genevieve

-Side scraper

Page 14: The Gehring Site: An Analysis of a Middle Woodland Lithic Assemblage in the American Bottom

Results

• Spear Points– 5% of tool assemblage– Norton

• Ste. Genevieve– Unidentified

• Burlington– Etley

• Burlington

• Cores• -3% of tool assemblage• Bipolar reduction

– Heat-treated Burlington• Multidirectional

– Burlington

Middle Woodland Diagnostics of Plowzone and Surface

• Plowzone– 49 blades

• Surface– 121 blades– Waubesa point– Dickson point

Page 16: The Gehring Site: An Analysis of a Middle Woodland Lithic Assemblage in the American Bottom

Conclusion• Holding Phase

• Farming– Hoe flakes

• Tool production site?

• Trade versus migration

• Regions of interaction– Southern Illinois, Illinois river valley, southwestern Illinois

• Trade versus migration?

Acknowledgments

• I want to thank Dr. Holt for all of the wisdom that she shared, without her guidance this research would not have been possible

• Larry Kinsella for making my comparative collection without which the unidentified category would be much larger.

• Miranda Yancey and Ken Farnsworth for looking over my first attempts at lithic analysis and for guiding me in the right direction.
