About

Yellowstone sits over a magma chamber 8 km below the surface — the same hot spot that produced the Snake River Plain as North America drifted southwest over it. Last supereruption: ~640,000 years ago, ejecting ~1,000 km³ of material. The 55 × 80 km caldera is visible in the relief as a broad depression. Geysers, hot springs, and mudpots — over 10,000 of them — are powered by groundwater meeting the heat-flow anomaly above the magma. First national park in the world, established 1872.
