Gros Cap Reef Lighthouse
Location & Light Range
About Gros Cap Reef Lighthouse
This white, skeletal steel tower, standing 18 meters tall, was built in 1953 to mark the southwest edge of Gros Cap Reef. It guards the entrance to the St. Marys River from Lake Superior. The light is displayed from a skeletal mast atop a 3-story keeper's quarters. A red flash is shown every 5 seconds, visible for nearly 13 nautical miles. The structure is built on a concrete crib designed with a knife-edge prow to break up ice. It is located approximately 10.5 kilometers from Sault Ste. Marie.
Why it matters: The lighthouse warns mariners of the Gros Cap Reef and is essential for guiding vessels into the St. Marys River, a critical shipping lane for traffic bound for the Soo Locks.
