Strange ‘yellow brick road to Atlantis’ discovered at the bottom of Pacific Ocean

Nearly 70% of Earth’s surface is covered by water, making seas and oceans prime sites for uncovering geological and historical treasures. In 2022, marine biologists discovered a peculiar geological formation in an unexplored part of the Pacific Ocean, dubbing it the “yellow brick road to Atlantis.” The Ocean Exploration Trust's EVNautilus shared a video of this fascinating find on their YouTube page.

The "yellow brick road" was found atop an undersea mountain near Hawaii. The scientists were astonished upon its discovery. In the footage, one researcher mentions wanting to sample the manganese crust due to a strange pattern visible on it.

Using a machine's claws, they extracted a chunk of the shiny, charcoal-grey ferromanganese crust. “That’s not sediment, that’s like baked crust. You can peel it off,” one of them says. “It's like bricks and cobblestone,” says another. Suddenly one of the researchers exclaims, “It’s the road to Atlantis!” Another adds, “That’s a really unique feature.”

“This is the yellow brick road,” someone else from the team exclaims. Another one says, “Are you kidding me? This is crazy.” One researcher says she feels like they’re on Mount Vesuvius, excavating. One of the team members shouts, “This is bizarre!”

As per HISTORY, Atlantis is a mythical island nation mentioned in Greek philosopher Plato’s dialogues “Timaeus” and “Critias.” Plato describes Atlantis as an island larger than Libya and Asia Minor put together, located in the Atlantic just beyond the Pillars of Hercules, generally assumed to mean the Strait of Gibraltar. After a series of earthquakes and floods, this island sank into a muddy sea. The oceanographers believe that they have stumbled upon this lost city.

However, what they called the “yellow brick road to Atlantis” was an example of ancient active volcanic geology, they wrote in the video description. They first discovered this structure when they dived on the Liliʻuokalani Ridge within Papahānaumokuākea Marine National Monument (PMNM). Swirls of seamounts rose from the seabed.

At the summit of Nootka Seamount, the team spotted a "dried lake bed" formation, which was later identified as a fractured flow of hyaloclastite rock, a volcanic rock formed in high-energy eruptions where many rock fragments settle to the seabed. “The unique 90-degree fractures are likely related to heating and cooling stress from multiple eruptions at this baked margin,” they wrote.

As shown in the footage, the team sampled basalts coated with ferromanganese crusts throughout the seamount chain at different depths and oxygen levels. They said one of these rocks “almost resembled a sponge.” 

According to Vice, this team of oceanographers, first stepped aboard the EV Nautilus research vessel as part of the Ocean Exploration Trust to explore this region. The project is part of an expedition called Luʻuaeaahikiikekumu (Luʻu-a-ea-a-hiki-i-ke-kumu), which represents the journey into the foundation and origin of the oceans or islands. In this particular project, the aim was to explore the PMNM, a U.S. marine conservation area in the North Pacific Ocean outside of Hawaii. As per NautilusLive, this expedition was funded by NOAA Ocean Exploration via the Ocean Exploration Cooperative Institute with additional support from the NOAA Office of National Marine Sanctuaries.

As of the footage's posting, only 3% of the seafloor had been mapped. Researchers plan to use mapping equipment to create more detailed maps and uncover more secrets about this underwater area.
