  • Summary

  • Vibrant colours disguise hidden dangers in the depth’s of Yellowstone’s hot springs. Despite the deadly temperatures, microbial life still thrives in the boiling, mineral-rich waters. In this episode we look at the mechanisms behind the hot springs and geysers, and how tiny creatures thrive where others dare not go.
