Oak Island has been intermittently owned by treasure hunters ever since early settler stories started appearing in the late 1700s.[14] The hunt for treasure got so extensive that in 1965 a causeway was built from the western end of the island to Crandall's Point on the mainland, two hundred metres away in order to bring heavy machinery onto the island.[15] Oak Island has had several different recent owners which include a treasure hunter named Dan Blankenship, who initially partnered with "Oak Island Tours Inc." run by David Tobias.
