The Welling site in Coshocton County, Ohio, was an important Paleo-Indian locality on the edge of the Walhonding River Valley, valued for its nearby Upper Mercer flint source. Evidence shows it served not just as a quarry and workshop but also as an outcrop-related base camp where people made tools, processed food and materials, and gathered socially. Excavations in 1965 uncovered 54 fluted Paleo-Indian points and abundant flint debris, showing tool production at many stages. Most tools used local stone, though a few came from Vanport flint, suggesting wider connections. Dating roughly from 10,000 to 11,800 BC, the site preserves evidence of some of the region’s earliest inhabitants and later Archaic reuse.
