Lake Superior Rock Picker's Guide
by Bruce Mueller and Kevin Gauthier
This guidebook is for anyone who has walked along a Lake Superior beach, picked up a stone, and wondered, "What is this?" A section of color photographs is included to help with identification. With great detail and helpful illustrations, the authors 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. See: Details
