It's been the object of devotion and derision... it's been bandied about by scientists, academics and amateur sleuths. And now the Kensington Runestone is being hauled to Sweden. Farmer Olaf Ohman unearthed the runestone on his western Minnesota farm back in 1898. The rock bears an inscription which some believe to be the writings of Nordic explorers dating from the year 1392. But many academics over the years have pronouced the runestone a modern forgery. Swedish scientists are holding a conference in October to study the Kensington Runestone and recent evidence that supports its validity. Geologist Scott Wolter runs a forensic geology business in the Twin Cities. He first heard of the runestone three years ago when he was hired by the Runestone museum in Alexandria to conduct tests.
