Ice cauldrons are ice formations within glaciers that cover some subglacial volcanoes. They can have circular to oblong forms. They can have circular to oblong forms. Their surface areas reach from some meters (as indentations or holes in the ice) to up to 1 or more kilometers (as bowl shaped depressions).
Articles relating to cauldrons, large pots for cooking or boiling over an open fire, with a lid and frequently with an arc-shaped hanger and/or integral handles or feet. There is a rich history of cauldron lore in religion, mythology, and folklore.
A Bronze Age cauldron, and flesh-hook, made from sheet bronze. The Holy Grail of Arthurian legend is sometimes referred to as a "cauldron", although traditionally the grail is thought of as a hand-held cup rather than the large pot that the word "cauldron" usually is used to mean. This may have resulted from the combination of the grail legend ...
A chaldron (also chauldron or chalder) was an English measure of dry volume, mostly used for coal; the word itself is an obsolete spelling of cauldron. It was used from the 13th century onwards, nominally until 1963, when it was abolished by the Weights and Measures Act 1963 , but in practice until the end of 1835, when the Weights and Measures ...
[citation needed] Snow and ice have much lower thermal diffusivities than air. Thermal diffusivity is a measure of the speed at which temperature waves can penetrate a substance. Snow and ice are many orders of magnitude less efficient at diffusing heat than air. Snow cover insulates the ground surface, and sea ice insulates the underlying ...
Glacial pothole in Bloomington on the St. Croix River at Interstate State Park, Wisconsin, U.S.. A giant's kettle, also known as either a giant's cauldron, moulin pothole, or glacial pothole, is a typically large and cylindrical pothole drilled in solid rock underlying a glacier either by water descending down a deep moulin or by gravel rotating in the bed of subglacial meltwater stream.

In winter regions that do not have permafrost, the subnivean zone maintains a temperature of close to 32 °F (0 °C) regardless of the temperature above the snow cover, once the snow cover has reached a depth of six inches (15 cm) or more. The sinuous tunnels left by these small mammals can be seen from above when the snow melts to the final ...
The Greenland ice sheet is the second largest ice sheet in the world, and the water which it holds, if completely melted, would raise sea levels globally by 7.2 metres (24 ft). [25] [26] Due to global warming, the ice sheet is melting at an accelerating rate, adding almost 1 mm to global sea levels every year. [27]
