3-d depiction of hodgkins seamount bowie seamount in background bowie seamount formed submarine eruptions along fissures in seabed throughout last glacial, or wisconsinian , period, began 110,000 years ago , ended between 15,000 , 10,000 years ago. while submarine volcanoes in pacific ocean more 1 million years old, bowie seamount relatively young. base formed less 1 million years ago, summit shows evidence of volcanic activity 18,000 years ago. recent in geological terms, suggesting volcano may yet have ongoing volcanic activity. close bowie s submerged summit, former coastlines cut wave actions , beach deposits show submarine volcano once have stood above sea level, either single volcanic island or small cluster of shoals have been volcanically active. sea levels during last glacial period, when bowie seamount formed, @ least 100 m (300 ft) lower today. map of kodiak-bowie seamount chain
