Stalagmite.

I checked in translator.com, and it says stalagmite
It can be seen that the stalactite has united with the stalagmite below
If a stalactite and a stalagmite joined it would form a column.
32.7m stalagmite in CAVES OF AGGTELEK KARST AND SLOVAK KARST
No, a stalagmite rises from the floor. A stalactite hangs from the roof
A stalagmite is an elongated collection of minerals found rising from cave floors.
A stagaltite is a round or tapering mineral spire that rises from the floor of a cave. Composed largely of calcium compounds, this solid geologic structure takes a long, long time to form. The stalagmite is the "compliment" of the stalactite, which hangs from the roof of a cave. A link to a related question can be found below.
A Stalagmite forms on a cave floor from the dripping of Mineral Rich water.
Stalagmites and stalactites can take thousands of years to reach just a few inches. The rate of growth for a stalagmite is based on the amount of water that is flowing through the rocks and the amount of Ca dissolved in it, but they most certainly do not grow overnight. So, no, no human could stand still long enough to have a stalagmite form on them.
Calcium Carbonate. Both are usually found in lime stone caves. The stalagmite is seen projecting upward from the floor. The stalagmite from the caves roof. The stalagmite will often feed the stalagmite from the moisture dripping from its pointed end. However many are found alone fed by the dripping moisture from the caves roof.
