Gros Cap Reef Light
By Dave Wobser

Gros Cap Reef Light, sometimes called Gros Cap Crib Light, is a modern Aid to Navigation and is one of less attractive lights on the Great Lakes.

The station was built in 1953 to mark the end of the Gros Cap Reefs which extend out from the Canadian shore near the entrance to the St. Marys River. A lightship had served this location beginning in 1927.

The light is opposite Point Iroquois on the US side of the river.

The square white concrete structure is topped by a helipad. The concrete crib has a unique plow shape to its up river side to help break the ice and storms that come down from Whitefish Bay.

The flashing white light is displayed 45 feet above water level. The station also has a radio beacon and fog signal. It is fully automated. The helipad appears to have been added at the time of automation. Electricity is supplied by underwater cable from the mainland.

Gros Cap is the last check point for up bound ships traveling the St. Marys River under control of the USCG Soo Traffic.

Gros Cap is visible from Point Iroquois, with binoculars, but is best seen by boat.
