The Kensington Runestone is a 200-pound slab of greywacke covered in runes on its face and side, believed to have been created in modern times to claim that Scandinavian explorers reached the middle of North America in the 14th century. It was found in 1898 in the largely rural township of Solem, Douglas County, Minnesota, and named after the nearest settlement, Kensington. Almost all Runologists and experts in Scandinavian linguistics consider the runestone to be a 19th-century hoax. The runestone has been analyzed and dismissed repeatedly without local effect. The community of Kensington is solidly behind the runestone, which has transcended its asserted cultural importance to the Scandinavian community and has "taken on a life of its own".
