It is now generally accepted the Leif Eriksson sailed from Greenland across the Davis Strait and made landfalls on the North American continent almost a thousand years ago, but what happened in this vast area during the next five hundred years has long been a source of disagreement among scholars. Using new archeological, scientific, and documentary information (much of it in Scandinavian languages that are a bar to most Western historians), this book confronts many of the unanswered questions about early exploration and colonization along the shores of the Davis Strait.
