Nature
Booming Ice Chasm is a remote ice cave high in Alberta’s Crowsnest Pass, near Mount Sentry on the Continental Divide. First noticed in 2005 and entered in 2008, it has since been explored and mapped by members of the Alberta Speleological Society to 961 metres in length and 179 metres in depth. Its cold-trap structure keeps temperatures below freezing year-round, sustaining perennial ice, a glacier-like ice fall, a frozen waterfall, and an ice-sealed lake. The cave has attracted scientific interest for microorganisms that may have medical value, but its concealed entrance, steep approach, smooth ice, and incomplete mapping make it hazardous and unsuitable for tourism.
