Publisher's Synopsis
This is the eighth book in the "Midwest Roadside Geology Series". Here I take you on a roadside bedrock tour from Wawa, Ontario west past Thunder Bay to the Ontario-Minnesota border. The north section of Ontario Route 587. The outcrops we cover are all Precambrian and extend back into the Archean to nearly 3 billion years ago. The book is in full color, with additional charts, definitions, and details on 40 stops. All the stops include exact GPS locations with photos. Some have additional maps and diagrams.
