Dan began searching for the island's alleged treasure in 1965 after he read about the Oak Island legend in an issue of Reader's Digest while he was living in Florida.

He eventually moved to Nova Scotia, Canada, in 1970 to search full-time for Oak Island's legendary fortune and spent over 50 years searching, drilling and digging for treasure.

"It is way too late [to turn back]," Dan said in his bio on the show's official website.

"It's been too late for a good many years. I had a good contracting business in Florida. I had friends, a good reputation and I shucked it all to come up here and make a gamble."

The Curse of Oak Island premiered on History in 2014 and its sixth season is currently airing on the network.

The series follows brothers Rick Lagina and Marty Lagina, Dan's son David Blankenship, and Marty's former college roommate Craig Tester on their quest to find a mythical secret treasure on an island in Canada.
