Similar to lava stalagmites, ice stalagmites form very quickly within hours or days. Unlike lava stalagmites however, they may grow back as long as water and temperatures are suitable. Ice stalagmites are more common than their stalactite counterparts because warmer air rises to the ceilings of caves and may raise temperatures to above freezing.

A stalactite (UK: / ˈ s t æ l ə k ˌ t aɪ t /, US: / s t ə ˈ l æ k t aɪ t /; from Ancient Greek σταλακτός (stalaktós) 'dripping', from σταλάσσειν (stalássein) 'to drip') [1] is a mineral formation that hangs from the ceiling of caves, hot springs, or man-made structures such as ...
Broomstick stalagmites are very tall and spindly; Totem pole stalagmites are also tall and shaped like their namesakes; Fried egg stalagmites are small, typically wider than they are tall; Stalagnate results when stalactites and stalagmites meet or when stalactites reach the floor of the cave; Flowstone is sheet like and found on cave floors ...
Stalagmites or flowstone may form where the water drops hit the cave floor. Soda straws are some of the most fragile of speleothems. Like helictites, they can be easily crushed or broken by the slightest touch. Because of this, soda straws are rarely seen within arm's reach in show caves or others with unrestricted access.
A brinicle (brine icicle, also known as an ice stalactite) is a downward-growing hollow tube of ice enclosing a plume of descending brine that is formed beneath developing sea ice. As seawater freezes in the polar ocean, salt brine concentrates are expelled from the sea ice, creating a downward flow of dense, extremely cold, saline water , with ...
Calthemite rimstone or gours can form beneath concrete structures on a floor with a gradual sloping surface or on the side of rounded stalagmites. When the leachate drip rate is more frequent than 1 drop per minute, most of the calcium carbonate is carried by the leachate from the underside of the concrete structure to the ground, where ...
Helictites are, perhaps, the most delicate of cave formations. They are usually made of needle-form calcite and aragonite. Helictite forms have been described in several types: ribbon helictites, saws, rods, butterflies, "hands", curly-fries, and "clumps of worms". They typically have radial symmetry. They can be easily crushed or broken by the ...
Luray Caverns, previously Luray Cave, is a cave just west of Luray, Virginia, United States, which has drawn many visitors since its discovery in 1878.The cavern system is adorned with speleothems such as columns, mud flows, stalactites, stalagmites, flowstone, and mirrored pools.
