About this map

The northern reaches of Isle Royale are defined by the parallel elevations of Minong Ridge and Greenstone Ridge, which create the long, linear troughs for inland water bodies like Harvey Lake and Hatchet Lake. Along the Lake Superior coast, the jagged shoreline of Todd Harbor is protected by a series of rocky outcroppings, including Wilson Island and Taylor Island.

Evidence of historical copper exploration is found at the Haytown Mine, located inland from the Todd Harbor Campground. For hikers and researchers, the map traces the critical transit routes of the era, specifically the Minong Trail and the Greenstone Ridge Trail, which follow the island's spine. The southern portion of the quadrangle descends toward the expansive Siskiwit Lake, showing the primitive state of this wilderness area within Isle Royale National Park during the mid-1980s.
