The Gros Cap Reef Lighthouse (officially, the Canadian Coast Guard Gros Cap Crib Lightstation) at the Whitefish Bay entrance to the St. Marys River is 20 kilometers / 12 miles west of Sault Ste Marie. The Lightstation lies 3 kilometers / 2 miles offshore from the hamlet of Gros Cap, Ontario and lies 4 kilometers / 2.5 miles offshore from Michigan’s Point Iroquois lighthouse.

Built by the Canadian Government in 1953, it replaced a lightship anchored offshore.  The three-storey tiered red and white square concrete structure (height above the water, 18 meters / 59 feet) rests upon a concrete crib / pier which in turn rests upon the shallow Gros Cap reef (reef water depth depth, 5-7 meters / 17-24 feet; the nearby shipping channel depth, 10 meters / 30 feet; water depth 1 kilometer / 1/2 mile northwest, 30 meters / 100 feet). To lessen the destructive impact of moving ice floes and/or storms, from Lake Superior, the lighthouse has a unique plow shape or “ice nose” at its front. Originally, the lighthouse required a staff of three keepers at any one time; in the 1980’s, the keepers were replaced when the lighthouse was automated and converted to a unmanned lightstation. A helipad was also added at this time.  A tower mounted non directional approach beacon, connected to the Sault Ste. Marie Airport, has also been removed from the lightstation. Currently, the lightstation has a radio beacon, fog signal, and light; the light flashes every five seconds and is visible for 20 kilometers / 12 miles. 

The coldest / harshest winter (2014) in 37 years led to +90% ice coverage of the Great Lakes.
