Isle Royale National Park is defined by its dramatic southwestern ridges and protected harbors in this mid-1980s survey. The landscape is dominated by the parallel rises of Minong Ridge, Greenstone Ridge, and Red Oak Ridge, which dictated the routes of the Minong Trail and Greenstone Trail. Evidence of the island's industrial past remains at the Wendigo Mines near Washington Creek, while the settlement at Windigo serves as a modern focal point for park operations, featuring a Ranger Station and Washington Creek Campground. The shoreline is heavily indented, providing shelter at Washington Harbor and Grace Harbor, with numerous small islands like Johns Island and Thompson Island dotting the entrance to the North Gap. The presence of a Gaging Station and Radio Tower reflect the ongoing scientific and communications infrastructure required for this isolated location.
