Gros Cap Reefs Light, Navigation lighthouse at entrance of St. Mary's River, Sault Ste. Marie, Canada.
The concrete tower rises 18 meters above water level, featuring a three-story keeper's quarters with a skeletal mast structure and red trim details.
The Canadian Coast Guard replaced a 1923 lightship with this permanent lighthouse in 1953 to guide vessels through the challenging waters of Lake Superior.
The lighthouse stands as a symbol of maritime navigation evolution, marking the transition point between Lake Superior and the St. Mary's River system.
The lighthouse emits a red flash every 5 seconds, with a visibility range of 12 nautical miles, and includes a helicopter landing pad for maintenance access.
The structure incorporates a ship-like design with a pointed prow and forward pilot house, built upon a submerged crib foundation in Lake Superior.
