How cold is an ice cave?
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.
What causes Icecaves?
The first type of ice cave is formed by meltwater streams carving labyrinths in the bases of glaciers or by streams and wind hollowing out tunnels in snowfields. Frozen lakes, icicles, and ice draperies are common formations. Helictite-like icicles also form where air currents deflect the freezing water.

How do ice caves stay cold?
Once ice has formed in the cave, it acts like a buffer to stabilize the cave’s temperature. If warm air passes through, some of the ice starts to melt. The reverse is also true — when cold air gets in, liquid water in the cave will freeze, releasing energy and stopping the cave from being as cold as outside.
How are sea caves formed?
Sea caves, also known as littoral caves, are formed where a rock wall contains a zone of weakness. In the Channel Islands, caves are formed where faults in the basalts are exposed to the force of waves. Caves along faults tend to be very long, narrow and straight.
How are glacier caves formed?
Glacier caves form within the ice of a glacier. Glacier caves are often carved out by water running through or under the glacier’s ice.
