Isle Royale Virtual CacheLocated on the trail from the Ranger III dock to the Rock Harbor Lodge this plaque commemorates Stephen Tyng Mather who laid the foundation for the National Park Service.
Isle Royale National Park, a wilderness archipelago 45 miles long and 9 miles wide at its widest point encompasses 850 square miles including submerged lands that extend 4.5 miles out into Lake Superior. Receiving authorization in 1931 and officially established as national park land in 1940, this past fishing and copper mining island was actually formed some 1.2 billion years ago as the result of rising lava seeping through cracks in the Superior Basin. Leaving waves of ridges and valleys that were additionally sculpted by major glacial ice sheets, a bountiful wilderness remains intact. Predominately untouched, the archipelago received official wilderness designation in 1976 and in 1980 the United Nations recognized the island and surrounding waters as a National Biosphere Reserve.Please submit a photo of your gps at the Stephen Tyng Mather plaque to receive credit for this find. Enjoy your trip to this beautiful area.
