 Cobb–Eickelberg Seamount chain

The Cobb–Eickelberg Seamount chain is an underwater volcanic mountain range located in the Pacific Ocean, off the coast of the northwestern United States, particularly near the state of Washington. This seamount chain is part of the larger system of seamounts and volcanic features that are associated with hotspot volcanic activity, which occurs as tectonic plates move over stationary magma plumes in the Earth's mantle.
