The notion that Oak Island might be home to pirate treasure had long been part of local lore. This idea got a jumpstart in 1795 when, according to accounts, a young man walking on the beach saw a low depression in the ground. This circular spot made it look like a hole had been dug and filled in again. Furthermore, it appeared that a nearby tree had once supported a pulley system, which can be used to raise or lower heavy things by rope.
