Exploring the shifting, glowing ice cathedrals hidden deep within active glaciers

My glacier cave discoveries - Eddy Cartaya · 8:03 · Video: TED-Ed · Watch at the source

In short: Climber Eddy Cartaya shares his experiences exploring glacier caves, which are dynamic, ever-changing environments. He explains how these fragile, beautiful spaces are shaped by warm air and water, revealing a world of vibrant colors and unexpected discoveries.

Cartaya and his climbing partner, Brent McGregor, were the first to explore three specific glacier caves, which they named Snow Dragon, Pure Imagination, and Frozen Minotaur. These caves are not static; they are constantly morphing due to the influence of warm water and air.

Inside these environments, the ice displays vivid blue and green hues. The caves also serve as repositories for artifacts that fall from the ceiling, offering a unique glimpse into the materials trapped within the ice.
