It may look similar to the yellow brick road in The Wizard of Oz, or perhaps a hidden path to the mythical lost city of Atlantis.
But deep-sea researchers who spotted the incredible rock formation say it is actually an example of ancient active volcanic geology on the ocean floor near Hawaii.
The strange-looking feature, which resembles a road paved in cobblestones, was located in the Liliʻuokalani Ridge in the Papahānaumokuakea Marine National Monument (PMNM) in the Pacific Ocean.
PMNM is one of the largest marine conservation areas in the world – bigger than all the national parks in the US combined – and researchers have only explored about three per cent of its sea floor.
The crew of Exploration Vessel Nautilus research ship caught sight of the formation and described it as a ‘yellow brick road’ and ‘the road to Atlantis’ in a video of the discovery.

‘It’s the road to Atlantis,’ a researcher on the radio can be heard saying.
‘The yellow brick road?’ another adds, while a separate member team member calls it ‘bizarre’ and ‘crazy’.
The team said: ‘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 Lili*uokalani Ridge within Papah*naumokuakea Marine National Monument.’
Nautilus spent most of April studying the geology and biological systems of ‘seamounts’ – underwater mountains with volcanic origins.
The team added in a statement: ‘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.
‘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.’

Nautilus has recorded all sorts of unusual sea life, including dumbo octopuses and ‘piglet squids’.
An E/V Nautilus spokesperson said: ‘Our exploration of this never-before-surveyed area is helping researchers take a deeper look at life on and within the rocky slopes of these deep, ancient seamounts.
‘These studies will help provide baseline information on the living communities of seamounts which can inform management and conservation measures.’
