Bowie hotspot

Bowie hotspot is believed to be perhaps 100 to 150 km (60 to 90 mi) wide and underlain by a mantle plume that is relatively deep.

[1] Eruptions from the Bowie hotspot have left a trail of underwater mountains across the Pacific, called the Kodiak-Bowie Seamount chain,[2] which is an underwater mountain region of seamounts along a line beneath the northern Pacific Ocean.

Geological studies show that the base of Bowie Seamount formed less than a million years ago.

The summit of Bowie Seamount is even younger and shows signs of having been active as recently as 18,000 years ago.

Because of its shallow depth, some geologists believe Bowie Seamount was an active volcanic island throughout last ice age.
