Introduction.
In a stunning find resembling something from a science fiction book, researchers studying marine life have discovered a peculiar geological formation shaped like a ‘yellow brick road’ on the coast of the pacific ocean. The structure, which was captured by underwater drones, has garnered attention both from the scientific community as well as the general public. Situated at a new unexplored zone close to Hawaii, this formation defies known concepts about the geology of the ocean’s floors and raises new possibilities about the powerful processes that shape the planet’s most remote regions. This discovery was made while conducting a survey at routine intervals which underlines the fact that a large portion of the earth’s oceans are still uncharted territory. As stated by Noah, less than 20% of the oceans can be said to have been mapped using modern high precision tools. This lack of knowledge makes finds like ‘yellow brick road’ of great significance as they highlight the extensive uncharted territories in marine sciences.
The Discovery:
The “yellow brick road” was found during an expedition led by the Ocean Exploration Trust where they used their latest research vessel, the Nautilus. The team utilized high-res sonar imaging and remotely operated vehicles to map the seafloor around the Lili’uokalani Ridge which is located within Papahānaumokuākea Marine National Monument, Hawaii.
The primary goal of the expedition, hosted by the “Ocean Exploration Cooperative Institute” program, is to delve into the inadequately studied areas of the Pacific. Sherman, the chief scientist aboard the Nautilus, recalled his eureka moment, saying this: “Initially, we thought this was a malfunction in the imaging capture. However, as the ROV (Remotely Operated Vehicle) advanced, the geometric precision of the blocks was startling. This was different from any natural formation that we had cataloged in the past. The light, during the deep-sea explorations, reflected off the surfaces of the minerals in a surreal manner which looked like a golden ‘pathway’ and that shocked each and every one of us.”
The ROV has images of geometric formations that were previously striking at around 3000 meters or 9800 feet about the Nautilus. These images show stunning geometric formations that span almost 100 meters in length. It is theorized by scientists that this structure is made from hundreds of rectangular blocks approximately 30-50 cm wide and yellowish in color resembling cobbles or the yellow wizard road from The Wizard of Oz.
Geological Explanations
Even though the formation may appear artificial, several scientists have provided natural reasoning for its formation, each having convincing proof from other similar geological phenomena observed across the globe:
- Volcanic Activity
The Pacific Ocean contains the “Yellow Brick Road”, which is hypothesized to be formed from lava flows, as well as the the most extensive volcanic systems on Earth, including underwater seamounts and hydrothermal vents. There are also Tessellated Pavements formed in Cyprus and Tasmania that have become tourist attractions. Not only do they tessellate, but they also resemble pavements.
“While basaltic lava is rapidly cooled subaqueously, contraction forces tend to fracture it into astonishingly uniform polygonal patterns. The combination of these fractures with stain build up over minerals surmised to be strategically placed throughout time make it seem like crafted pathways,” said Dr. James Carlton, a Marine Geologist from the University of Hawaii. “What’s astonishing here is the regularity of the pattern is jaw dropping, there are clearly defined order and geometric shapes which indicates cooling conditions we’re still in search of understanding.”
- Hydrothermal Alteration
The release of hydrothermal vents at over 400°C has the potential to change the structure of surrounding rocks due to the emission of fluids rich in minerals. The yellow color visible could also be due to sulfur and iron oxides which inhabit common regions. Throughout history, these hydrothermal minerals could have changed the rocks to give the roads their illusive paved appearance through the process of metamorpohis.
Hydrothermal systems in the Mariana Trench are posited to have similar types of color alteration where the iron rich fluids precipitate to give off vivid orange or yellow crusts. Dr Wong says: ‘The chemical signatures we’re seeing in preliminary scans match known hydrothermal alteration patterns, especially with the presence of iron sulfides that tend to have a golden yellow coloration under water conditions with light. This strongly fortifies the hypothesis that the distinctive chemical reactions occurring in the vicinity of the ‘road’ is the cause for the chemical reactions that give off such hues and not construction faults.”
- Erosion and Sedimentation
Ocean currents and sedimentation can create patterns that are not possible to form in the seafloor either over geological time intervals or just by randomly forming deposits. The blocks may have formed via some combination of erosion and the depositing of minerals – in a mosaic pattern – and the area’s highly localized current patterns plus periodic earthquake activity may have helped explain the relatively uniform geometry of the formation.
And sediment core samples from a nearby surrounding area show that layers of volcanic ash and carbonate deposits alternate with each other, dating back nearly 10 million years. The clastic response? Dr. Alan Fitz says: What we are probably seeing is the product of all the multiple geological processes working in conjunction — volcanic activity caused the initial fractures, hydrothermal fluids changed the chemistry, then ocean currents slowly eroded and reshaped the formation over the course of millions of years. The precise patterning is a work of art by nature, and not human engineering. “
- Biological Influence
Though more unlikely as a primary explanation, some researchers posit that microbial activity may also have participated in the formation, as certain extremophile bacteria do produce mineral structures through biomineralization processes, but nothing on the scale of this was previously documented.
“Extremophile bacteria do indeed form micro-scale mineral deposits, ” says microbiologist Dr. Lisa Wong, “particularly iron-oxidizing bacteria that live in hydrothermal environments. “So they couldn’t make such giant, geometrical formations itself, but the activities of their metabolic systems may be a part of the patterning and texture we’re seeing here, though. Getting that macro-scale organization would require biological processes so far beyond what we’ve seen working in marine ecosystems.
Comparisons to Other Mysterious Formations
All too soon, however, researchers begin to question exactly what’s under the ocean floor. The first is the fact that some of these “yellow brick roads” have been found – not actually on the ocean floor, but deep beneath.
The Baltic Sea Anomaly (2011) The sonar image of a disk-like object located 60 meters below sea surface that created controversy as to whether it was originally a sunken UFO or simply an artificially made impression due to unusual sonar shadows.
Bimini Road (1968): A 0. 8 km long submerged rock formation in the Bahamas formed by rectangular blocks of limestone. Some thought it was a remnant of the lost city of Atlantis, but epigeological evidence proved that it was natural beachrock formed by the tidal sedimentation of the sea approximately 2, 000-3, 000 years ago.
Japanese “Atlantis” (Yonaguni Monument): Discovered in 1986 off the coast of Japan, this huge underwater monument includes terraced walls and what seem to be decorated steps. Some archaeologists believe it to be evidence for human construction dating back 10, 000 years, but most geologists attribute it to fracturing of natural sandstone caused by strong currents.
The reasons of this are as follows: 1) To the best of our knowledge, no human or animal has ever been observed on or near the “yellow brick road”, but its enormous depth (3000m compared to Yonaguni’s 25m), and it is chemically similar to deep sea volcanic events, not shallow-water erosion. 2) The uniformity of the blocks is far higher than usual, which creates an exciting research challenge for scientists.
Scientific Significance
Besides the visual appeal and viral attention, the discovery has great implications for many disciplines of science.
Understanding Deep-Sea Geology
This formation could provide the first glimpse of volcanoes under extreme pressures, ” Dr. Sherman adds. “These are lava flow behavior at depths and pressures that we have never previously been able to study in the direct sense. The cooling patterns here could rewrite a whole bunch of our knowledge about submarine volcanism. ”

Public Engagement with Science
It ‘s also in part due to the online nature of the discovery, but the opportunity for education has clearly arisen as well. With the announcement coming three months ago, thousands of students flocked to Ocean Exploration Trust’s website in the hours after the news broke to discover what had been discovered.
Debunking Myths
Even with all the hype, scientists have been quick to discredit all the more outrageous theories with solid science.
No Evidence of Human or Alien Construction
The only thing stopping human intervention is the depth itself – in the 3, 000-meter depth, the pressure is greater than 300 atmospheres (4, 400 psi). “Even today’s nuclear submarine has a maximum operating depth of maybe 900 meters, ” Dr. Fitz says. Ancient civilizations had no technology nor any kind of compelling reason to create structures at such depths.
Natural, Not Supernatural
The formation does look visually striking, but it ‘s actually parallel to that we are familiar with in geology. And the human fascination with patterns ( pareidolia ) is also the reason many people think it is artificial. Dr. Carlton continues ” We see the same psychological effect with the ‘ Face on Mars ‘ or cloud shapes. Our brains are wired to notice patterns even where there was no intent on there being any.
