The full conversation with Scott Wolter is out now, on the YouTube channel.
Before Scott left the UK, the collector who showed him the artifacts gave him a package closed with a wax seal. The collector said that its contents relate to a site he thinks might be connected to Atlantis. Inside are what looks like a plan view of a structure, and an underwater photograph of square, block-like shapes. The coordinates put the site just off the coast of Lisbon.
If the structures are human-made and 90 feet below the water, the estimate is probably at least 8,000 to 9,000 years ago.
