Booming Ice Chasm

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. The name derives from the acoustics of the cave. The cave was discovered in 2005 by a caver who identified it using Google Earth and first explored and mapped in 2008 by the Alberta Speleological Society
