Yellowstone sits above a vast magma reservoir under Wyoming

Yellowstone sits above a vast magma reservoir under Wyoming

Yellowstone National Park rests atop a huge magma and partially molten rock system under Wyoming and neighboring states — the engine behind its geysers, hot springs, and caldera landscape.

Past eruptions emptied chambers and collapsed the surface into broad basins; today’s heat still drives Old Faithful and thousands of hydrothermal features.

Beauty here is geothermal power in costume. The park’s steam and rainbow pools are surface whispers of a restless deep.
