Excerpt from The Geologic Story of Isle Royale National Park Isle Royale is an outstanding example of relatively undisturbed northwoods lake wilderness. But more than simple preservation of such an environment is involved in its inclusion in our National Park System. Its isola tion from the mainland provides an almost untouched laboratory for re search in the natural sciences, espe cially those studies whose very nature depends upon such isolation.
