/ref> Like the rest of the Kodiak-Bowie seamounts, it was formed by the Bowie hotspot
The Bowie hotspot is a volcanic hotspot, located west of Haida Gwaii in the Pacific Ocean.
Almost all magma created by the hotspot has the composition of basalt, and so the volcanoes are constructed almost entirely of this igneous rock. The eru ...
