Adam Walker inside a newly found cave, called Booming Ice Chasm, beneath the Rocky Mountains. Crystal clear ice is several meters thick and makes people feel like they're flying

The cave has unique acoustics as falling rocks crash and boom when they tumble down the 140 metre deep cave, making it hard to converse

Water dripping into the cave's entrance causes a huge ice slide to form, which explorers say is treacherous as the ice is crystal clear and difficult to navigate

As melting snow and rainwater trickle down the cave entrance, it is transformed into an amazing natural frozen water slide

Explorers say navigating across the crystal clear ice gives them a feeling of flying as they become disoriented
