With cold weather already here, we thought this 7-minute video would inspire a little winter exploration. Produced by Uncage the Soul Video, the piece was shot Mount Hood’s Sandy Glacier caves and documents the decay over the past decade.

“It is one of the most challenging environments to film in. Not only does its remote location mean hauling hundreds of pounds of equipment high up on the slopes of Mt Hood, but once inside the cave, the wet, cold, dark, and dirty conditions create a myriad of complications. There was a staggering amount of structural collapse and rockfall that was observed and managing risk while filming was a top priority,” producers wrote in their notes on the video.
