Recent field re-investigations at the Paleo Crossing site, Ohio—a site first excavated by the Cleveland Museum of Natural History in the early 1990s—were aimed at relocating and expanding the original checkerboard of excavation units. It was in these that postmolds were found and inferred to be from a Clovis-age structure. Yet, unexcavated units in the checkerboard made it impossible to determine if there were additional postmolds or if they aligned or formed a pattern that would warrant the inference of a structure. To resolve these matters, we undertook new excavations at the site. Our field investigations re-located the checkerboard and expanded the original excavation. We found several additional postmolds, but their radiocarbon ages fall within just the last several centuries. Nor were we able to replicate the site’s previously-reported late Pleistocene radiocarbon ages or find other evidence to support the onetime presence of a Clovis-age structure. Claims for a Clovis age structure at Paleo Crossing are therefore not supported.
