Markov Guyot

Markov Guyot is an underwater volcanic mountain with a flat summit in the Pacific Ocean. A guyot is a seamount whose top was flattened by erosion before it sank below sea level.

Its flat summit is typical of a guyot. The usual explanation is that the volcano once rose near or above sea level, was eroded flat, and later subsided as the oceanic crust moved and cooled.

The feature was designated to honor a Russian figure during 20th-century oceanographic expeditions. The exact namesake should be checked against the relevant seamount gazetteer before being stated more precisely.

It is located in the Pacific Ocean as part of the region's underwater volcanic topography. Its position is normally identified through nautical charts and oceanographic gazetteers rather than a visible shoreline landmark.
