It gives a snapshot profile of the beaches open to the public along the North Shore, tips for rock pickers and a section on Lake Superior's geologic roots. Each type of rock is beautifully and clearly drawn for maximum ease in identification, including: Granite, Basalt, Quartz, and Thomsonite, to name just a few. There is an expanded section covering Lake Superior Agates that is especially helpful, and very clear maps to help you along the way."
