In rural Minnesota a farmer named Olaf Ohman found a mysterious runestone.  Engraved into the stone was an epic tale of adventure and bloodshed, apparently written by Norse explorers.  The discovery of the Kensington Runestone sparked a worldwide discussion about what we know about pre-Columbus European exploration.
