Abstract The Oak Island Money Pit has long been the subject of treasure hunting lore, with one of its most famous elements being the so-called “80-foot stone” or “90-foot stone,” allegedly discovered in the early 19th century. This paper critically examines historical records, engineering considerations, and the evolution of the Oak Island narrative to argue that the stone — described as inscribed with cryptic symbols — likely never existed. The evidence suggests the stone emerged as part of legend-building and fundraising efforts by later treasure-seekers, rather than as a factual archaeological artifact.
