This guidebook is for anyone who has walked along a Lake Superior beach, picked up a stone, and wondered, “What is this?” Bruce Mueller and Kevin Gauthier researched Lake Superior’s entire shoreline to create this thorough and accessible volume. With great detail and helpful illustrations, they describe the kind of rocks you’ll find—including copper, iron, and gold—provide hints for telling the stones apart, and show you the best places to find each stone. Also included are suggestions for handling the stones, including the best polishing methods, and fascinating information on the rocks’ origins.

A section of color photographs is included to help with identification.
