Castner Ice
Purchase Print

Hoarfrost and columnar ice on the roof of a glacier cave beneath the Castner Glacier. These enormous caves form from water flowing beneath the glacier. Warmer air in the summer often helps melt out and open up the entrances. This was taken during a short hike yesterday. Check out the full story with lots of photos and video below!
