Speleology
This term describes the scientific study of caves and cave systems.
What is speleology?
During the War of 1812, enslaved laborers extracted calcium nitrate for this purpose.
What is making gunpowder?
This endangered bat species commonly found in Mammoth Cave is federally protected.
What is the Indiana bat?
The Green River is classified as this type of stream relative to Mammoth Cave’s passages.
What is a base-level stream?
This modern technology is used to create highly accurate 3D maps of cave systems.
What is LiDAR?
Mammoth Cave is considered a “solution cave,” meaning it formed primarily through this chemical process.
What is dissolution of limestone by acidic water?
This 19th-century disease led to an unsuccessful attempt to use Mammoth Cave as a treatment center.
What is tuberculosis?
This adaptation—loss of pigmentation and eyesight—is common in obligate cave dwellers.
What is troglomorphism?
This impermeable rock layer above the limestone helps limit vertical water flow.
What is sandstone (cap rock)?
Mammoth Cave surpassed this Kentucky cave system in mapped length, confirming its world-record status.
What is the Flint Ridge cave system?
The relatively dry upper levels of Mammoth Cave formed during this earlier geological phase.
What is when the water table was higher (phreatic zone conditions)?
The cave wars of the early 1900s were primarily conflicts over this.
What is tourism competition and land ownership?
This term refers to animals that use caves but must return to the surface to survive.
What are trogloxenes?
The step-like levels of Mammoth Cave formed as a result of this long-term process.
What is gradual lowering of the regional water table?
The historic 1972 connection between Mammoth Cave and Flint Ridge was made by this cave research group.
What is the Cave Research Foundation?
This type of cave passage, formed completely underwater, is characterized by smooth, rounded walls.
What is a phreatic passage?
This system of forced land acquisition helped establish the national park in the 1930s.
What is eminent domain?
The energy base of many cave ecosystems depends on this external input.
What is organic matter transported from the surface (detritus/guano)?
This term describes the boundary between saturated and unsaturated zones underground.
What is the water table?
This mapping method involves measuring distance, direction, and inclination between survey points.
What is cave surveying (or compass-and-tape surveying)?
The lack of abundant stalactites in Mammoth Cave is largely due to this geologic factor.
What is limited vertical water infiltration through the overlying sandstone cap?
This explorer not only mapped large portions of the cave but correctly hypothesized its connection to surface rivers.
Who is Stephen Bishop?
This rare crustacean species found in Mammoth Cave is an example of a federally endangered troglobite.
What is the Kentucky cave shrimp?
The chemical equation for limestone dissolution involves carbon dioxide and water forming this weak acid.
What is carbonic acid (H₂CO₃)?
This designation recognizes Mammoth Cave for both natural and cultural significance on a global scale.
What is a UNESCO World Heritage Site?
