What is the difference between a stalactite and a stalagmite?
Most stalagmites have rounded or flattened tips. There are many other types of mineral formations found in caves. Some deposits are named based on their appearances, such as a showerhead, which is a hollow cone-shaped formation, or a conulite, which is a “splash cup” that forms when water dripping rapidly through the cave ceiling flings ...

Origin of Bermuda and Its Caves - NOAA Ocean Exploration
This acidic groundwater acted to dissolve the limestone, forming lateral voids. Over time, the dissolution process enlarged these voids to form liner conduits, caves, and underground lakes. Dripping water created massive stalactites and stalagmites …

Some of these passages show evidence of subterranean river flow carrying runoff from Harrington Sound towards the ocean during periods of lower sea level (Fig. 2). Massive stalactites and stalagmites are present in virtually all parts of the underwater cave and are another indication of the cave's long history as a dry cave (Fig. 3).
