Darkest Hour
The worst moment ever recorded in regards to human exploration of Oak Island, unfortunately, came in 1959. Robert Restall and his son were at the forefront of Oak Island’s deepest corners before losing their lives in an accident. After finding a stone with “1704” engraved on it, Robert died upon inhaling carbon monoxide. Robert Jr. tried saving his father, but also suffered the same fate. To make matters worse, two workers also died trying to save the father and son.
