Carlsbad Caverns - speleothems
Detailed Description
Most of Carlsbad Caverns' speleothems (cave deposits such as these stalagmites) consist of the mineral calcite (CaCO3) that precipitates from groundwater that enters a cavern. Some speleothems are also composed of aragonite and gypsum (Davis, 2000; NPS, 2009; NPS, 2010).
