Deep sea researchers spot bizarre 'yellow brick road to Atlantis' on ocean floor
Researchers studying the depths of the ocean in Hawaii uncovered what appeared to be a 'yellow brick road' spanning across the ocean floor.
All that was missing was a scarecrow, a lion and a tin man - but rather than leading to a wizard, this road was suggested by one of the researchers involved to be 'the road to Atlantis'.
The 'lost city of Atlantis' is an idea that's caused a lot of curiosity over time, so naturally any potential clue under the sea warrants a closer look.
This particular sight was spotted by deep-sea researchers in the Liliʻuokalani Ridge in the Papahānaumokuakea Marine National Monument (PMNM) in the Pacific Ocean, near Hawaii.

It features a series of yellow-tinged stones which lie next to each other at neat angles, as if they had been purposefully arranged.
It would be easy to imagine a huge, underwater city looming at the end of the road, which is probably why one of the researchers did jokingly dub it the 'road to Atlantis' in the video.
However, the team soon offered further insight to the finding and explained it's actually a natural occurence.
In a statement, the team said: "At the summit of Nootka Seamount, the team spotted a 'dried lake bed' formation, now IDed 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."
The researchers added: "What may look like a yellow brick road to the mythical city of Atlantis is really an example of ancient active volcanic geology.
"Our Corps of Exploration have witnessed incredibly unique and fascinating geological formations while diving on the Liliʻuokalani Ridge within the Papahānaumokuakea Marine National Monument."
The PMNM is the largest contiguous fully-protected conservation areas in the world, covering 582,578 square miles of the Pacific Ocean - an area larger than all of the US's national parks combined.
It is one of only 24 World Heritage sites in the US, and joined Hawaii Volcanoes National Park to become one of two in Hawaii.
The huge expanse of the area means that only a small percent of it has been explored - so it's not entirely surprising that the researchers stumbled upon some noteworthy sights.
In their statement, the researchers added: "Throughout the seamount chain, the team also sampled basalts coated with ferromanganese (iron-manganese) crusts from across different depths and oxygen saturations as well as an interesting-looking pumice rock that almost resembled a sponge."
