Gros Cap Reefs Light, Navigation lighthouse at entrance of St. Mary's River, Sault Ste. Marie, Canada.
Gros Cap Reefs Light is a lighthouse at the entrance of the St. Mary's River in Sault Ste. Marie, Canada. The concrete tower includes a three-story keeper's dwelling and a skeletal mast framework painted with red trim.
A lightship from 1923 was replaced in 1953 by this permanent lighthouse to guide vessels through the challenging waters of Lake Superior. The Canadian Coast Guard built it to improve navigation at this critical transition point.
The beacon marks where Lake Superior meets the St. Mary's River, serving as a key navigation point for ships entering this critical waterway. Mariners and local residents recognize it as the gateway between these two major water systems.
The beacon sends a red flash every 5 seconds and can be seen from ships up to 12 nautical miles away. A helicopter landing pad provides access for maintenance work.
The structure has a ship-like design with a pointed prow and forward pilot house. It rests on a submerged crib foundation beneath Lake Superior's waters.
