These and many more amazing facts await the curious traveler in The Michigan Roadside Naturalist, J. Alan and Margaret B. Holman's captivating guide to the natural treasures of Michigan. A perfect accompaniment to the classic Michigan Trees and The Forests of Michigan, this user-friendly guide offers a Who's Who of the geology, biology, and archaeology of the Great Lakes State, as well as highway adventures along the state's major routes.
