The Helictite subsection of the Calcite section is used to record stations where helictites are observed. Helictites are classified as to their specific form in the corresponding field.
Helictites are formed of calcite or aragonite and grow in erratic, twisting projections that seem to defy gravity. They form by hydrostatic water pressure and wicking caused by evaporation. Helictites are classified on the Carlsbad Cavern National Park Cave Inventory Form as to their shape and form and as to whether ot not they formed under water due to the common-ion effect.
