Art Grindstone is the hard-nosed storyteller behind Unexplained.co, a veteran investigator whose life’s work sits at the crossroads of the paranormal, fringe science, and the shadows most people try not to look into. With decades spent chasing impossible stories — black-budget psychic programs, vanished Cold War experiments, desert rituals that sparked UFO waves, and the strange phenomena buried in America’s forgotten backroads — Art brings a rare combination of skepticism, awe, and journalistic precision. He’s not here to debunk. He’s not here to blindly believe. He follows the evidence wherever it leads — even when it leads someplace deeply uncomfortable. Known for his immersive, cinematic style and his ability to turn obscure research into gripping narrative, Art has built a devoted following across podcasts, long-form features, documentaries, and serialized investigations. His interviews are direct. His analysis is unflinching. His voice has become a staple in the modern paranormal renaissance — the guy people turn to when a story is too strange, too complex, or too dangerous for anyone else to touch. Off-mic, Art works with a distributed network of researchers, archivists, and field operatives who help surface the stories mainstream media ignores. On-mic, he transforms their findings into meticulous, high-impact reporting that refuses to insult the intelligence of true believers. His philosophy is simple: Take the phenomenon seriously. Treat the audience with respect. Tell the story as if the world depends on it — because sometimes it does. When Art Grindstone digs into a case, he isn’t just chasing a mystery. He’s tracing the fault lines of reality itself.

A resurfaced claim about a possible lost city off the Louisiana coast is getting fresh traction in late March 2026. Retired architect and amateur researcher George Gelé says sonar images collected over decades show submerged structures near the Chandeleur Islands, including a pyramid-like formation roughly 280 feet tall, potentially dating back more than 12,000 years.

The most sensational details are exactly why the story is spreading: an underwater metropolis, a pyramid allegedly tied geographically to Giza, and local reports that compasses and electronics behave strangely near the site.

What’s Happening

Coverage from AOL/New York Post and The Daily Beast pushed the long-running claim back into the 2026 news cycle.
Gelé says the site sits roughly 50 miles east of New Orleans, with structures around 30 feet below the water surface and buried under additional sediment.
He has reportedly argued that granite blocks appear present in a region where granite does not naturally occur.
A local fisherman cited in coverage claimed instrument problems near the site, including spinning compasses and electronics cutting out.
The major caveat: the claims have not been validated in peer-reviewed literature, and no mainstream archaeological confirmation has been published.

Why It Matters

1. It is basically an American Atlantis story

Lost civilization narratives always travel, and this one adds Gulf Coast mystery, pyramid symbolism, and magnetic anomalies.

2. It blends archaeology with classic paranormal motifs

Once compasses start spinning, the story stops being just archaeology and becomes an anomaly narrative.

3. It is highly debatable, which makes it sticky

Skeptics can point to exaggeration, sonar over-interpretation, and lack of peer review. Believers can point to repeat local lore, site persistence, and the emotional power of a hidden ancient city.

4. It taps directly into prehistory revisionism

Any claim of advanced structures dating to 12,000 years ago immediately plugs into bigger debates about lost civilizations, cataclysms, and suppressed history.
