A 'yellow brick road' beneath the Pacific Ocean traced to ancient volcanic activity

Detailed summary

A strange formation resembling a yellow brick road was discovered on the Pacific Ocean floor during an expedition by the Ocean Exploration Trust’s research vessel E/V Nautilus. The structure was found at a depth of 1,029 metres near Nootka Seamount, within the Papahānaumokuākea Marine National Monument. Its unusually regular pattern made it resemble a brick sidewalk, but scientists identified it as a natural geological formation.According to a report published by The Oceanography Society on the Ocean Exploration Trust’s 2022 field season, the formation likely consists of fractured hyaloclastite, a type of volcanic rock created when hot magma meets cold water.
