f all time is what happened on Oak Island in Nova Scotia? Was there treasure buried there and is it still there? One of the most popular cable television shows ever, The Curse of Oak Island on History Channel, investigated the mystery spending millions of dollars over ten seasons and could not find the treasure. Both Don Ruh and Scott Wolter have had firsthand involvement with the island and its mysteries over the years, Don sharing two maps with Rick and Marty Lagina via his friend and co-researcher Zena Halpern, and Scott with his multiple visits to the island. However, they had little interest in the mystery until early in 2023 when a trove of encrypted documents came to Don as part of their research of the Knights' Templar Cremona Document materials. Once decoded, the five messages and three sketches and one new map of the island revealed shockingly detailed information about who constructed, " The Underground Project," put treasure there and what happened to it. Finally, the over six-centuries-long mystery has been solved. Incredibly, the documents also provide new insight into the fabled Holy Grail.
