A piece of central Minnesota history allegedly tied back to the Vikings of the 1300's is going to be the center of attention on a new Science Channel show. The Kensington Runestone is a 202-pound stone tablet that was discovered by Olof Öhman, a Swedish immigrant in Solem Township in Douglas County. The stone was said to be unearthed when Olof was clearing a field in 1898 and is inscribed with a record left behind by Scandinavian explorers in the 14th century. The authenticity of the stone has been widely debated: Some Norwegians claimed the stone was a Swedish hoax and there were similar Swedish accusations because the stone references a joint expedition of Norwegians and Swedes. It is thought to be more than coincidental that the stone was found among Scandinavian newcomers in Minnesota, still struggling for acceptance and quite proud of their Nordic heritage
