Closer view of the glacier in the winter A glacier cave under Mendenhall Glacier. Mendenhall Glacier (Tlingit: Áakʼw Tʼáak Sítʼ) is a glacier about 13.6 miles (21.9 km) long located in Mendenhall Valley, about 12 miles (19 km) from downtown Juneau in the southeast area of the U.S. state of Alaska.

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 formations in the cave were formed by thawing snow which drained into the cave and froze during winter. [4] Since the entrance to the caves is open year-round, chilly winter winds blow into the cave and freeze the snow inside. In summer, a cold wind from inside the cave blows toward the entrance and prevents the formations from melting.
