Ever wondered why Yellowstone doesn’t stink of sulfur like other volcanoes? Scientists were baffled by the missing sulfur dioxide—until they realized it’s being ‘scrubbed’ underground! Hot water in the park’s crazy hydrothermal system traps the gas and transforms it into that classic rotten egg smell (hydrogen sulfide) you catch around the hot springs. Turns out, the missing gas is just hiding in plain (smelly) sight! #Science #Yellowstone #ScienceMystery
