underground cave that was formed by ice, cave that contains ice

This article is about caves that contain ice. For caves formed in ice, see glacier cave. The term ice cave refers to 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.
