A partly submerged glacier cave on Perito Moreno Glacier. The ice facade is approximately 60 m high Ice formations in the Titlis glacier cave. A glacier cave is a cave formed within the ice of a glacier. Glacier caves are often called ice caves, but the latter term is properly used to describe bedrock caves that contain year-round ice. [1]
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.

Subglacial streams are conduits of glacial meltwater that flow at the base of glaciers and ice caps. [1] Meltwater from the glacial surface travels downward throughout the glacier, forming an englacial drainage system consisting of a network of passages that eventually reach the bedrock below, where they form subglacial streams.

Bedrock is dissolved by carbonic acid in rainwater, groundwater, or humic acids from decaying vegetation, that seeps through bedding planes, faults, joints, and the like.. Over time, the surface terrain breaks up into clints separated by grikes and punctuated by sinkholes into which streams may disappear, crevices expand as the walls are dissolved to become caves or cave sy
The cave was discovered by Americans as early as 1889 and referred to as the Crook County Ice Caves. [4] Arnold Ice Cave was also the site of an early ice mining operation. [5] The ice was sold to the city of Bend and relieved the ice market which was cornered by one of the early saloon keepers. [4] At one time, a trench was chopped into the ...
The United States Code defines speleogens as "relief features on the walls, ceiling, and floor of any cave or lava tube which are part of the surrounding bedrock, including anastomoses, scallops, meander niches, petromorphs and rock pendants in solution caves and similar features unique to volcanic caves."
