As the Sandy Glacier slowly slides down Mount Hood in Oregon, the caves and tunnels inside it morph annually thanks to warm water from above and warm air from below. At TEDYouth, Cartaya takes us inside these magical spaces where the ice glows in bright blues and greens, and where artifacts rain from the ceiling.

 

A ranger at Deschutes National Forest in Oregon, Eddy Cartaya not only solves cave crimes -- he also explores the ever-changing system of caves within Mount Hood's Sandy Glacier.
