For an easy-to-follow guide to the most commonly found minerals on the mine dumps in Michigan's Upper Peninsula, you can't do better than to consult our own Susan Robinson's Mineral Identification Guide for the Copper Country's Poor-Rock Piles. Susan, author of the Rocks & Minerals article series on artists and their work, is an artist in her own right. She wrote and illustrated this attractive brochure as a handy reference for beginning collectors and first-time visitors to Upper Michigan. Look for it at mineral and gift shops in the area. It's a perfect size to slip into your shirt pocket when you go to the Copper Country's Keweenaw Week
