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.

The ice formations in the cave were formed by thawing snow which drained into the cave and froze during winter.

In summer, a cold wind from inside the cave blows toward the entrance and prevents the formations from melting.
