The stone has been long lost to time, first reportedly being kept in the home of the Smith family, then popping up in the window of a shop in Halifax. As for the stone's writing, no rubbings of it exist, but the markings are generally accepted to look a specific way. In 1949, a reverend named A.T. Kempton supposedly translated the writing, and argued that it said: "40 feet below 2 million pounds are buried."
That seems very clear. Keep digging into the Money Pit, and after another 40 feet, the famed treasure of Oak Island — anything from Marie Antoinette's crown jewels to the mythical riches of the Knights Templar — will be found. Except that a guest expert from one episode of "The Curse of Oak Island" disagrees.
In Season 2, Episode 5 — aptly titled "The 90-Foot Stone" — cryptographer Daniel Ronnstam interprets the writing as being "two codes in one," combining both English and Spanish translations. Ronnstam's version of the code comes to "at 80 feet corn long narrow sea inlet drain." He also suggests that this could be a set of instructions aimed at helping excavators and treasure hunters avoid the pit's many booby traps.
