One of two ships from the Franklin Expedition, which were assumed to have sunk after being icebound, was recently discovered in Victoria Strait in the Arctic Ocean, near where Inuits had last reported seeing it in 1845.

It’s still unknown whether this ship is the HMS Erebus or HMS Terror, whose 128 crewmembers perished in the frozen wilderness. Rescue parties searched for the crew until 1859, and traces of 70 sailors have been found over the years, including the bodies of three crew found in the 1980s.

The ship was located in 11 meters of water, upright and largely intact.

The original search parties for the lost expedition were instrumental in opening the Canadian Arctic to discovery in the 19th century. Watch this video to find out which recently discovered clues helped them finally locate the wreck.
