The Isle Royale Light stands on long, rocky Menagerie Island via Isle Royale's south shore at the entry to Siskiwit Bay. Reachable only by private boat, it features a 61-foot double-walled octagonal sandstone tower, with a black lantern and gallery. It was completed and operative in 1875, and automated in 1913. The original Fourth Order Fresnel lens and subsequent light systems have been replaced with a 12-volt solar power 300 mm Tidelands Signal Acrylic Optic, which sends its beam out 10 miles.
