Having just returned from visiting the Peterborough petroglyphs, I am truly overcome with the amount of PC (i.e. Indian culture) that is displayed on the part of the Canadian Gov't. Dr. Fell presents a well thought out and logic argument for a Norse orgin for the petroglyphs. The Canadian Gov't does not and views the petroglyphs as Indian in origin, but can not explain what they mean or why they are there. Dr. Fell's explanation is a logical answer to what happened to the tonnes of copper that were mined in the area in the BC (the Indians did not use), why the mining was done, and stopped. "At some point in the distant past, the carvers ceased coming to the site" so goes the Gov't version. "The boats here do not appear to resemble the birchbark canoes used by the natives in this region". The read in the book is at times long- not from lack of content, but from Dr. Fell's scientic approach to the matter. This is the way science used to operate, before PC became a concern. In light of Kennewick Man and other recent discoveries in the science of Archeology, maybe Dr. Fell has latched on to the toe of the early history of N. America.
