Stalagmite

A stalagmite (UK: /ˈstæləɡˌmaɪt/, US: /stəˈlæɡmaɪt/; from Greek σταλαγμίτης (stalagmítēs); from Ancient Greek σταλαγμίας (stalagmías) 'dropping, trickling', and -ίτης (-ítēs) 'one connected to, a member of') is a type of rock formation that rises from the floor of a cave due to the accumulation of material deposited on the floor from ceiling drippings. Stalagmites are typically composed of calcium carbonate, but may consist of lava, mud, peat, pitch, sand, sinter, and amberat (crystallized urine of pack rats).

For the elongate mineral formation hanging down from a cave ceiling, see Stalactite. For the type of fungus, see Stalagmites (fungus).

The corresponding formation hanging down from the ceiling of a cave is a stalactite. Mnemonics have been developed for which word refers to which type of formation; one is that stalactite has a C for "ceiling", and stalagmite has a G for "ground", another is that, as with ants in the pants, the mites go up and the tights (tites) come down.
