The American Runestone

Hoping to get answers about who carved the runestone, Peter Stormare and Elroy Balgaard meet with Scott Wolter, a forensic geologist who has studied the runestone for over 20 years.

Peter and Elroy take a closer look at the stone's history and how the Vikings traveled across the North Atlantic. They also meet the grandson of the man who found the stone and hear about the tragedies that have followed the family.

The boys meet Bob Voyles, a mysterious man who takes them to a hidden place where he says there are medieval artifacts buried, and learn more about how the Vikings traveled the world.

Scott Wolter calls the guys and tells them about a new scientific test that could prove Olof's innocence, but he needs their help to test the stone. They also receive the results of the DNA test.

Just as they are about to start digging at a promising archeological site, Peter and Elroy receive bad news and have to reconsider. They catch Darwin and learn a secret that gives them new hope.

The guys have finally gathered materials to carry out Scott's test. Darwin's tip leads them to find artifacts at the site where the stone was found. This could be the discovery that changes history.
