There is a towering mountain range within Oregon, Washington, and Idaho which quickly rose 6,900 feet from the ground. Known as the Blue Mountains, these formed due to an unusual response to one of the planet's largest repeated floods of lavas around 16 million years ago. Today's video discusses how this isolated mountain range formed.
