BrownBearSeamount,partoftheCobb-EickelbergSeamountchain which is a range of undersea mountains located in thePacific Ocean, is separated in two areas, the Northwestern and Southern side.
Brown Bear Seamount is a seamount (underwater volcano) approximately 300 mi (483 km) west of the coast of Oregon. The Cobb-Eickelberg seamount chain is a range of undersea mountains formed by volcanic activity of the Cobb hotspot located in the Pacific Ocean. The most studied seamounts that make up this chain are Axial, Brown Bear, Cobb, and Patton seamounts. It has not been affected by ocean spreading as much as its neighbor, and is therefore not quite as geologically complex.
