Eponge Guyot

Eponge Guyot is a flat-topped underwater mountain, or guyot, in the Pacific Ocean. Its level summit reflects erosion or wave planation when the volcanic structure was closer to sea level before subsiding.

A guyot is a seamount with a relatively broad, flat summit. The term comes from Arnold Henry Guyot, a nineteenth-century geographer and geologist.

Its shape records part of the history of an underwater volcanic landform and its movement relative to sea level. The summit and surrounding slopes can also provide habitat for deep-sea organisms.

No. It is submerged beneath the ocean, so it is classified as an undersea mountain rather than a present-day island. The catalog entry does not provide a verified depth or geographic coordinate.
