With it's dazzling turquoise walls and and huge open spaces, it's hard to imagine that this incredible frozen cavern was only formed at the beginning of 2012. But despite it's seemingly mystical allure, the fascinating natural phenomena is at risk of collapsing in on itself without warning.
Photographed by ice caver, Ron Gile, 55, the adventurer has known many caves collapse and disappear in his eight years exploring the local area. (Caters)
