Airmen's Cave
Airman's Cave is a cave located adjacent to the portion of Barton Creek located in Travis County in south Austin, Texas. The cave is long, and characterized by long crawls and tight passages. It lies inside the Barton Creek Greenbelt public park and is managed by the City of Austin's Parks and Recreation Department. Features Airman's Cave is formed within the Edwards limestone of the early Cretaceous, and was originally a feeder for Barton Springs before the water table lowered and the stream found a different course. It is home to a number of rare troglobite species, including '' Rhadine austinica'', ''Tartarocreagris intermedia'', ''Texella spinoperca'', and ''Texella mulaiki''. One of the more foreboding passages, found within sight of daylight, is the "Birth Canal": a tight, restricting tunnel that once discouraged many novice cavers from continuing further into the cave. Much deeper inside is a space known as the "Aggie Art Gallery," containing a reddish maroon c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cave
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgani ...

Caving
Caving – also known as spelunking in the United States and Canada and potholing in the United Kingdom and Ireland – is the recreational pastime of exploring wild cave systems (as distinguished from show caves). In contrast, speleology is the scientific study of caves and the cave environment.Caving in New Zealand (from Te Ara: The Encyclopedia of New Zealand, Accessed 2012-11.)

Fauna
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is '' funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Speleological Society
The National Speleological Society (NSS) is an organization formed in 1941 to advance the exploration, conservation, study, and understanding of caves in the United States. Originally headquartered in Washington D.C., its current offices are in Huntsville, Alabama. The organization engages in the research and scientific study, restoration, exploration, and protection of caves. It has more than 10,000 members in more than 250 grottos.

Grotto (National Speleological Society)
A Grotto is an internal organization of the National Speleological Society (NSS). They generally function as the local NSS chapter/club. Many Grottos however, operate in areas outside of their local area, with many operating in several states. Most Grottos also participate in Regions which are loose associations of Grottos. Regions are also an internal organization of the National Speleological Society. Organization Grottos are required to meet certain organizational requirements as outlined by the National Speleological Society. These include: * A constitution and bylaws that are submitted to, and approved by, the NSS * A minimum of at least five members of the Society * It is NSS policy that full membership in a Grotto requires NSS membership. However, in practice, this is often not the case. An annual report describing various aspects of the Grotto is submitted to the NSS. History The New England Grotto was the first NSS Grotto. It was chartered in 1941 with Clay Perry as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
