state as a submerged volcano 33 million years ago. Over time, as the
Pacific Plate moved steadily northwest, Patton Seamount has carried off the Bowie hotspot and into the Gulf of Alaska. New volcanoes were formed one after another over the hotspot, creating the Kodiak–Bowie Seamount chain.

Explorations of the Kodiak–Bowie
Seamount chain have shown that despite the fact that most of the seamounts were created by the Bowie hotspot, all are unique in their size, shape, and volcanic features. The seamounts teem with deep-sea

Giacomini Seamounts give an approximate average rate of movement along the chain of 6.5 cm (3 in) per year.
