Stalagmite
Elongate mineral formation found on a cave floor / From Wikipedia, the free encyclopedia
For the elongate mineral formation hanging down from a cave ceiling, see Stalactite. For the type of fungus, see Stalagmites (fungus).
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')[1] 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).[2][3]
