Steve Libert, a Michigan shipwreck hunter, claims to have discovered the wreck of Le Griffin, the first full-size European ship to sail in the Upper Great Lakes, which sank in 1679. Despite Libert's assertions, experts such as Wayne R. Lusardi and Valerie van Hees express skepticism, suggesting that previous discoveries of the ship have proven false. Meanwhile, Allen Exploration is investigating the Nuestra Señora de las Maravillas, a 17th-century Spanish galleon that sank in 1656, revealing connections to the infamous pirates of the Caribbean. This galleon, laden with treasure and contraband, met its demise after colliding with a reef during a storm, killing most of its 650 passengers. The ship is noted for its legendary riches, estimated at five million pieces of eight, and has been subject to numerous salvage operations since its sinking. Concerns over unregulated treasure hunting have led to government moratoriums, though recent licenses have allowed new exploration efforts.
