The Glass Mountain Ridge forms the northeast boundary of Long Valley Caldera. It consists of a sequence of lava domes, flows, and welded pyroclastic flows of rhyolite composition that were erupted between 2.1 and 0.8 million years ago.[6] Obsidian, a naturally occurring volcanic glass, can be found on the mountain.[7]
