For more than half a century, Dan Blankenship pursued one of the world’s most enduring mysteries with an intensity few could match.
But Oak Island is only part of Dan’s story.
He was remarkably intelligent, endlessly curious, funny, honest, passionate, stubborn and determined. He was a businessman and builder, a husband and father, a problem solver and a man who was never afraid of hard work. He questioned assumptions, trusted what he could observe for himself and believed that answers were earned through persistence.

He made it his life.

In 1965, Dan read the now-famous Reader’s Digest article about the mysterious Money Pit on Oak Island.
Something about the story captured him.
At the time, Dan had built a successful contracting business and a life in Florida. Walking away from that security to pursue an unsolved mystery on a small island off the coast of Nova Scotia was hardly the safe choice.
Dan made it anyway.
He uprooted his life and came to Nova Scotia, beginning a journey that would consume more than 50 years of his life. HISTORY later recounted Dan's own acknowledgment of just how much he had left behind in Florida to take that gamble.
What began as fascination became a lifelong pursuit of one fundamental question:
What really happened on Oak Island?

Dan was fascinated by the possibility of treasure, but his pursuit became about something larger.
He wanted the truth.
For generations, searchers had confronted unexplained structures, flooding, collapsed shafts, pieces of wood and other evidence beneath Oak Island. Theories multiplied, but definitive answers remained elusive.
Dan wanted evidence.
He studied the history. He examined previous searchers' work. He drilled, excavated, built, repaired and experimented. His construction background and natural ability to solve mechanical and engineering problems became invaluable in an environment where almost nothing went according to plan.
When equipment failed, Dan found another way.
When a theory didn't hold up, he reconsidered it.
When a hole flooded, he went back to work.
And when Oak Island refused to give up its answers, Dan refused to walk away.

Of all the places associated with Dan Blankenship, none became more closely connected to him than Borehole 10-X.
Dan's work at 10-X grew into one of the most ambitious undertakings of his search. The shaft eventually extended approximately 235 feet underground, northeast of the Money Pit. Decades later, 10-X remained important enough to the investigation that professional divers and modern imaging equipment were brought in to examine its depths.
But photographs of 10-X tell another story as well.
Dan wasn't directing the search from a distance.
He was there.
At the drill. Around the machinery. Working underground. Building, reinforcing, pumping, digging and solving whatever problem came next.
That hands-on determination defined his approach to Oak Island.

In the late 1960s, Dan Blankenship and businessman David Tobias joined forces in the Oak Island search, eventually establishing Triton Alliance.
Their work represented another major chapter in the island's modern history. Dan and Tobias acquired significant property interests on Oak Island and pursued investigations around the Money Pit, Smith's Cove, 10-X and other areas. HISTORY identifies Blankenship and Tobias among the searchers who acquired Oak Island land during this period.
The years that followed brought progress and disappointment, discoveries and disagreements, enormous physical challenges and financial risk.
Through all of it, Dan remained.

The determination that made Dan such a formidable searcher was only one part of who he was.
Those who knew him remember his intelligence and his ability to size up a problem quickly. They remember his honesty. His passion. His humor. His stories.
And they remember a man who could be wonderfully direct.
Dan didn't need everyone to agree with him.
He had spent decades examining Oak Island with his own eyes and working its ground with his own hands. He developed strong opinions because they were informed by a lifetime of experience.
There was toughness in him, certainly.
But there was also wit, curiosity, loyalty and a great capacity for storytelling.
It is that Dan—the person behind the photographs, machinery, shafts and television cameras—that this website and his memoir seek to preserve.

Decades after Dan first arrived on Oak Island, another pair of searchers entered the story.
Rick and Marty Lagina had also been captivated by the 1965 Reader’s Digest story. In 2006, the brothers acquired a major interest in the company that owned much of Oak Island and joined the continuing search.
By then, Dan possessed something no technology could replace:
decades of firsthand knowledge.
He knew the ground, the previous excavations, the theories, the failures and the unanswered questions. HISTORY described him as the man who knew the most about Oak Island's legends and closely guarded secrets.
When The Curse of Oak Island later brought the search to an international television audience, millions of people were introduced to Dan.
But television audiences were meeting a man whose search had already consumed most of a lifetime.
