Booming Ice Chasm is an ice cave in the Crowsnest Pass area of the Canadian Rockies. It is a cold-trap cave, where cold air enters the cave and is unable to leave, resulting in the entrance pitch and floor being covered in several metres of clear, smooth ice.[2] The name derives from the acoustics of the cave.[3] It was discovered, explored and mapped in 2008 by the Alberta Speleological Society.[1] An expedition led by Nicholaus Vieira was filmed by François-Xavier de Ruydts and became a 19-minute documentary, which takes the viewer inside the cave.[2][4]
