“Yellow brick road” – Unique formation found on Nootka Seamount
While diving on the Liliʻuokalani Ridge within Papahānaumokuakea Marine National Monument, the Ocean Exploration Trust expedition aboard the E/V Nautilus found what they described as an ‘incredibly unique and fascinating’ feature resembling a ‘yellow brick road’ to the city of Atlantis.
At the summit of Nootka Seamount, the team spotted a “dried lake bed” formation, now 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 formation was found at a depth of 1 029 m (3 375 feet).
