This book details the most in-depth and exhaustive investigation into what is arguably the most controversial historical artifact ever discovered in North America. The Kensington Rune Stone has been the subject of passionate debate over its authenticity since it was discovered in the roots of a tree near Kensington, Minnesota, by Olof Ohman in 1898. Through the presentation of compelling new evidence this book answers the many nagging questions that have puzzled investigators for the over 100 years. Much of this new evidence is truly startling and has led to the understanding of not only who carved the stone, but where they came from and why they came to North America. Co-authors geologist Scott Wolter and engineer Richard Nielsen present the evidence of their collective 25 years of research on the artifact. The results of their research present a compelling and convincing case.
