Raspberry Island Light
The Raspberry Island Lighthouse is a lighthouse located on the southern part of Raspberry Island, marking the west channel of the Apostle Islands in Lake Superior in Bayfield County, Wisconsin, near the city of Bayfield. It was erected in 1862, marking the western channel.
==History==
It is said to be "one of the few surviving wood framed lighthouses left on Lake Superior. The complex includes a square tower rising up from the attached Lighthouse keeper's quarters, a brick fog signal building, frame barn, brick oil house, boathouse, two outhouses, and a dock.〔(Wobser, David, Raspberry Island Light, boatnerd.com )〕
The light was automated in 1947 and was later transferred to the National Park Service as part of the Apostle Islands National Lakeshore. It was added to the National Register of Historic Places in 1977, part of reference number 77000145. Listed in the Library of Congress Historic American Buildings Survey, WI-312. The original Fresnel lens is on display at the Madeline Island Historical Museum.
The old battery system in the fog signal building was replaced by a solar powered 300 mm Tideland Signal acrylic optic atop a pole, which continues to light the island to this day.〔(【引用サイトリンク】author=Pepper, Terry )〕 The location is an active aid to navigation, with a characteristic white flash every 2.5 seconds.
