CAVES IN CANADIAN MOUNTAIN HAVE IMPRESSIVE FORMS

Caves in the limestone strata of the Canadian Rockies just across the boundary from our own Glacier National Park have an architecture all their own, different from the stalactite-pillared development familiar in most limestone caverns. While dripstone is not absent, it is not as abundant as it is elsewhere, and the rugged form of the rock itself is more in evidence, as shown here in the cave popularly known as the Dining Hall.
