Vikings in America

In 1000 AD, the Vikings made it to North America, establishing a base camp in Newfoundland at a site called L'Anse aux Meadows. But could they have made it further South to what is now the United States to build a permanent settlement called Vinland, which has been documented in legend, but has never been found? Forensic Geologist Scott Wolter thinks so. Now, he's hot on the trail of never before seen evidence and geologic clues that could prove it--including a message discovered off the coast of a forbidden island in Massachusetts that may have been left by famous Viking Voyager Leif Ericson himself.
