The entrance to Booming Ice Chasm was initially found by accident by members of the Alberta Speleological Society while attempting to reach a different cave in June, 2008. It was subsequently explored and mapped by the Alberta Speleological Society. Speleologist Chas Yonge considered that it is the largest ice cave in North America. The main shaft, although an inclined passage that is not completely vertical, is considered Canada's second deepest shaft due to the technical requirements of descent.
