The Long Valley

The Long Valley is a large volcanic basin in eastern California, formed by a massive eruption about 760,000 years ago. It’s a caldera, meaning a collapsed volcanic crater, roughly 20 miles long. The area is still geologically active, with ongoing geothermal activity like hot springs and volcanic vents, indicating the underlying magma remains restless. While it hasn't erupted significantly in recent history, scientists monitor the region for signs of potential future eruptions. The valley also features diverse ecosystems and scenic landscapes, making it a significant natural and geological area.
