Snow Dragon. Pure Imagination. Frozen Minotaur. These are the names Eddy Cartaya and his climbing partner Brent McGregor gave three glacier caves that they were the first to explore, caves that are morphing constantly thanks to warm water and warm air. At TEDYouth, Cartaya takes us inside these magical spaces where ice glows in bright blues and greens, and where artifacts rain from the ceiling.
