Glossary of caving and speleology

There are a number of terms that are used in connection with caves, caving and speleology. The following is an incomplete list.

A

• Anthodite - A speleothem (cave formation) composed of long needle-like crystals situated in clusters which radiate outward from a common base.

B

• Belly crawl - A passage that is very low
• Biospeleology - A branch of biology dedicated to the study of organisms that live in caves and are collectively referred to as troglofauna.
• Boulder choke - A collection of large rocks or rubble that obstructs the passage of a cave or mine. In order to progress through passages cavers often need to negotiate or clear boulder chokes.
• Buffoon - Also called a speleo-buffoon or cave-buffoon, a derogatory term referring to cavers who are unprepared and make poor decisions.^[1]

C

• Cave conservancy - A specialized land trust that primarily manages caves or karst features in the United States.

S

• Speleogen - A geological formation within a cave that has been created by the removal of bedrock, rather than as a secondary deposit.
• Speleogenesis - The origin and development of caves, the primary process that determines essential features of the hydrogeology of karst and guides its evolution.
• Spelunker - Someone who explores caves as a hobby^[3]
• Spelunking - Exploring caves as a hobby^[4]
• Squeeze - A tight passage
• Stygofauna - Small aquatic animals living in caves and aquifers
• Sump - A cave that is submerged under water. A sump may be static, with no inward or outward flow, or active, with continuous through-flow. Static sumps may also be connected underwater to active stream passage. When short in length, a sump may be called a duck.
• Suspension trauma - Also known as harness hang syndrome (HHS), or orthostatic intolerance, is an effect which occurs when the human body is held upright without any movement for a period of time.

T

• Terrace - A series of dams made of rimstone that slopes gently.^[5]
• Troglobite - An animal that lives entirely in the dark parts of caves
• Troglofauna - Small, non-aquatic cave-dwelling animals

W

• Whaletail - A type of descender produced from a block of aluminium block applies a variable degree of friction.^[6]
