An ice cave is any type of natural cave (most commonly lava tubes or limestone caves) that contains significant amounts of perennial (year-round) ice. At least a portion of the cave must have a temperature below 0 °C (32 °F) all year round, and water must have traveled into the cave’s cold zone.
The Ice Plug, the 'end' of the cave, was discovered by Mike Boon during a controversial solo trip in the winter of 1970. Soon thereafter cavers helped produce The Longest Cave, a National Film Board production, during which some side passages were explored. The first woman to the Ice Plug at the end of Castleguard Cave was Jane Mulkewich.

Strong winds tend to push ice higher and higher as ice piles build to five, ten, even 20 feet or more. Waves then carve out spectacular crevices and the freezing spray creates icicle-like formations.
Ice inside the cave Ice on the floor of the cave. The cave contains about 1,500 cubic metres (53,000 cu ft) or 220–260 cubic metres (7,800–9,200 cu ft) of ice, which stacks on the cave floor and the walls. The ice is decorated with stalagmites, stalactites and ice columns. [2] [7] It fills the deeper parts of the cave. [8]
