It is a basaltic volcano that erupted about 20,900,000 years ago,[2] with survey data that indicates it rises about 4,000 m (13,000 ft) above the local sea floor to a minimum depth of 419 m (1,375 ft).[1] It is just to the north of the Britannia Guyots and is connected to them by a ridge that rises about 2,000 m (6,600 ft) from the sea floor. It was described as a seamount in 1961.[3]
The waters above it are incorporated in the Central Eastern Marine Park, an Australian marine park.[4]
