The Columbia Plateau and Steens Basalt are the initial surfacing of the giant plume head.
Columbia Plateau —Yellowstone Hotspot Track (2 of 3)
When magma from the plume head reaches the surface, it flows across the surface as basalt.
Columbia Plateau —Yellowstone Hotspot Track
Volcanic rocks in the Pacific Northwest show the effects of a tectonic plate riding over a deep-mantle hotspot. Numbers are the Age of Initial Volcanism (Millions of Years Ago). Letters are abbreviations for Na... More
