The Kensington Runestone is a slab of greywacke stone covered in runes that was discovered in Western Minnesota, United States, in 1898. Olof Ohman, a Swedish immigrant, reported that he unearthed it from a field in the largely rural township of Solem in Douglas County. It was later named after the nearest settlement, Kensington.
The inscription purports to be a record left behind by Scandinavian explorers in the 14th century (internally dated to 1362). There has been a drawn-out debate regarding the stone's authenticity, but since the first scientific examination in 1910, the scholarly consensus has classified it as a 19th-century hoax, with some critics directly charging Ohman with fabrication. Nevertheless, there remains a community convinced of the stone's authenticity. The city of Kensington, Minnesota's website claims that the stone is genuine, that there were blue-eyed Blonde Mandan, and that Nicholas of Lynn, who was not an explorer, was the navigator of the Norse expedition.
