The Kensington Runestone

Record summary

The Kensington Runestone is a carved stone found by farmer Olof Öhman in Minnesota and inscribed with a purported 1362 account by Scandinavian explorers. Its authenticity has been disputed since its announcement. Linguistic features, rune forms, carving style, soil history, and the finder’s circumstances have been examined, with mainstream scholarship generally treating it as a nineteenth-century forgery, although advocates continue to argue for medieval origin. The case is useful for comparing archaeological authentication, nationalist narratives, and material evidence. AI-recalled, not a verified medieval expedition record.
