The idea of the yellow tile road was born with the novel The Wonderful Wizard of Oz by L. Frank Baum (1900), where a golden path is described that leads to the Emerald city and symbolizes the trip to personal fulfillment and discovery. In the famous adaptation to the 1939 cinema, that path became a visual icon thanks to the pioneering use of Technicolor: the bright yellow contrasted with the intense green of the city and the blue sky, marking the passage of Dorothy from Kansas’s gray routine to a fantasy world.
It turns out that in marine depths we had Another way of tile.
A geological finding. History dates back to 2022. During the Luʻuaaahikikekumu expeditiona scientific team aboard E/V Nautilus shipwhile exploring the chain of old submarine volcanoes of Liliʻuokalani Ridge, he ran into Rocking formation that remembered the mythical “road of yellow tiles” of the cinema.
The curious structure, located at the top of the submarine nootka, within the National Marino Monument Papahānaumokuākeait turned out to be an example of ancient volcanic geology: rock fragments generated by high -energy eruptions, known as hyaloclastitethat have fractured uniformly due to repeated cycles of heating and cooling by successive eruptions. This pattern, similar to the cracked of the surface of a Brownie, has conferred the rock an appearance of perfectly aligned cobblestone.
Origins and characteristics. Hialoclastite is formed when hot magma comes into contact with water, fragmenting into vitreous particles and accumulating in the seabed. Over time, these deposits are compacted and cemented, and, in cases like this, exposed to thermal changes that They produce rectilinear fissures.
The found sector showed a stretch of “baked scab” dry to touch, An optical effect that surprised the team and generated jokes on the “road to the Atlantis.” The inspection with the nautilus robotic arm allowed to collect samples from Ferromanganésic scabs (rich in iron and manganese oxides) that covered the background, a resource of scientific and industrial interest.
Importance of the mission. That was the First systematic exploration Of these submarine mountains, whose main objective is to understand the mysterious discontinuity that presents its alignment in the ocean bed. The finding of “road” joined other unique observations of the expedition, such as the filming of a strange agency nicknamed Headless Chickn Monsterstrengthening the idea that the area houses poorly documented biological and geological phenomena.
Beyond the visual anecdote, the identification and study of these formations provides key information about the Submarine eruptive processes and the tectonic evolution of the region, opening the door to new discoveries in one of the most remote and protected areas of the planet.
Scientific context. He find It was also framed in an international effort to map and understand the underwater structures that make up the hidden geography of the oceans. The formation of the “path” in Nootka Seamount Not only illustrates how volcanic activity can generate visually striking patterns, but also offers clues about the systems behavior submarine magmatic and its interaction with water in High energy environments.
Plus: These studies are essential to improve underwater volcanism models, evaluate potential mineral resources and understand how these geological habitats influence deep marine biodiversity, a field in which each expedition reveals more unknowns than certainties.
