"Working with an expedition cruise company that sails to the world's most remote places like Alaska and the Arctic, Eric Guth is constantly surrounded by large bodies of ice.
Six years ago, he spotted a small opening on the edge of Mendenhall Glacier in Juneau, Alaska. He hiked to it with the intent of walking around as he'd seen others do before. But something compelled him to look inside."
Now he has spent the last six years searching for glaciers, exploring them, and photographing the formations.
