Long Valley Road runs through the immense Long Valley Caldera, which is one of the largest calderas on earth. This caldera was formed by a massive eruption about 760,000 years ago. Evidence of this volcanic history is littered all around the region from all of the hot springs, Obsidian Dome, & Devil's Postpile National Monument.
