“Yellow brick road” – Unique formation found on Nootka Seamount

unique formation found at the summit of nootka seamount yellow brick road may 2022

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).
