About 99 percent of Isle Royale is federally-designated wilderness. One exception is the developed area at Rock Harbor, with a dock, lodge, store and some other buildings. There's a nature trail from Rock Harbor to Scoville Point. The first part has interpretive signs to tell people what they are seeing.
About halfway out, you leave the "developed" area and enter the "wilderness" area. In its wisdom, the National Park Service has erected this sign to tell you that in a wilderness, you don't get any more signs.
Somehow we made it out and back without getting lost.
