This book helps you to explore the over three billion years of geologic history exposed along the Roadside of the Upper Peninsula.
The authors and editors of this book explored the many roadsides and parks of the Upper Peninsula in order to gui.
All of this happened half a billion years or more before the first person set eyes on Lake Superior.
