History

The light is in fact about 9 miles (14 km) from the city of Green Bay, situated on the north side of the shipping channel.[3] It used much the same design as that of the Peshtigo Reef Light to the north: a cylindrical foundation containing several chambers was poured inside a steel form atop a timber crib, and a steel plate superstructure was set atop it.[4][3] This consisted of a single story round dwelling floor surmounted by a thin conical tower.[4] The lantern initially contained a fourth order Fresnel lens giving a red light; a short mast on the roof of the lantern bore a radiobeacon antenna.[2][4] The fog signal was a horn powered by compressed air.[4] The light was activated in 1935.[2]

Unlike its sister, whose dwelling was intended for emergency use only, this light was constantly manned by Coast Guard personnel, who served two-week rotating tours.[4][3] The dwelling encompassed not only the superstructure but part of the foundation as well, as evidenced by the ring of portholes in its side.[4] The light was automated in 1979 and continues in service.[2][4]
