Huron Lightship
This historic floating lighthouse, retired in 1970, is open to the public for seasonal tours. Lightships are floating lighthouses that are anchored in areas where it was too deep, expensive, or impractical to construct a lighthouse. Lightships displayed a light at the top of a mast and, in areas of fog, also sounded a fog signal and radio beacon. The fog signals used over the years consisted of bells, whistles, trumpets, sirens, and horns. Early fog horns were powered by steam and later by air compressors.
