Lambton (1922)
The Lambton was a Canadian Lighthouse Tender, named such because it traveled between lighthouses on Lake Superior checking in on keepers. On April 18, 1922, the Lambton found itself in a storm that lasted two days. It was last spotted by the ship Valcartier about 40 miles north of Whitefish Point on Lake Superior during the storm. To this day, the fate of the Lambton remains a mystery. No one knows where it sank; no wreckage of it has ever been found.
While one of many Great Lakes shipwrecks, the Lambton is important in that its disappearance sparked the creation of the Canadian Coast Guard in the Great Lakes. Today, there is a ship in the Coast Guard's Search and Rescue Service called the CCGS Cape Lambton, thereby keeping the memory of the Lambton alive.
