Paleo Crossing site, also known as the Old Dague Farm site, is an archaeological site near Sharon Center, Ohio in Medina County where Clovis artifacts dated to 10,980 BP ± 75 years Before Present were found. The Cleveland Museum of Natural History conducted an excavation from 1990 to 1993. The site provides evidence of Paleo-Indians in northern Ohio and may be the area's oldest residents and archaeologist Dr. David Brose believes that they may be "some of the oldest certain examples of human activity in the New World." The site contains charcoal recovered from refuse pits. There were also two post holes and blades and tools 80% of which were made from flint (Wyandotte chert) from the Ohio River Valley in Indiana, 500 miles from Paleo Crossing, which indicates that the hunter-gatherers had a widespread social network and traveled across distances relatively quickly. The post holes are evidence that there was a shelter built on the site.
