Tongue River Cave
Tongue River Cave is a cave in the Bighorn National Forest just west of Dayton, Wyoming. Historically notable for a wide variety of rare cave formations and animal species, the cave has suffered in recent decades from unrestricted traffic, vandalism, and the theft of many of the cave's speleothems. Deemed beyond preservation, the cave is now managed by the U.S. Forest Service as a "sacrifice cave".http://www.fs.fed.us/r2/bighorn/projects/planrevision/geographic/geoassessments/tongue.pdf The Big Horn National Forest closed the cave to the public in July, 2010 to prevent the spread of White nose syndrome, however the cave has since been reopened. Registration and decontamination of clothing and gear is now required to visit the cave per Forest Order. Geology Tongue River Cave is in the Bighorn dolomite. Mapped in 1969 by the National Speleological Society, Tongue River Cave contains 1.23 miles of passages. The cave is 106 feet deep. The cave is composed primarily of two s ...

Bighorn National Forest
The Bighorn National Forest is a U.S. National Forest located in northern Wyoming, United States and consists of over 1.1 million acres (4,500 km2). Created as a US Forest Reserve in 1897, it is one of the oldest government-protected forest lands in the U.S. The forest is well east of the continental divide and extends from the Montana border for a distance of 80 miles (130 km) along the spine of the Bighorn Mountains, an outlying mountain range separated from the rest of the Rocky Mountains by Bighorn Basin. Elevations range from 5,000 feet (1,500 m) along the sagebrush and grass-covered lowlands at the foot of the mountains, to 13,189 feet (4,020 m) on top of Cloud Peak, the highest point in the Bighorn Mountains. Around 99% of the land is above . The forest is named after the Bighorn River, which is partially fed by streams found in the forest. Streams in the range are fed primarily by snowmelt and snowmelt mixed with driving rainfall. Within the forest is the Cloud ...

Speleothems
A speleothem (; ) is a geological formation by mineral deposition (geology), deposits that accumulate over time in natural caves. Speleothems most commonly form in calcareous caves due to carbonate dissolution reactions. They can take a variety of forms, depending on their depositional history and environment. Their chemical composition, gradual growth, and preservation in caves make them useful paleoclimatology, paleoclimatic proxies. Chemical and physical characteristics More than 300 variations of cave mineral deposits have been identified. The vast majority of speleothems are calcareous, composed of calcium carbonate (CaCO3) minerals (calcite or aragonite). Less commonly, speleothems are made of calcium sulfate (gypsum or mirabilite) or opal. Speleothems of pure calcium carbonate or calcium sulfate are translucent and colorless. The presence of iron oxide or copper provides a reddish brown color. The presence of manganese oxide can create darker colors such as black or dark b ...

White Nose Syndrome
White-nose syndrome (WNS) is a fungal disease in North American bats which has resulted in the dramatic decrease of the bat population in the United States and Canada, reportedly killing millions as of 2018. The condition is named for a distinctive fungal growth around the muzzles and on the wings of hibernating bats. It was first identified from a February 2006 photo taken in a cave located in Schoharie County, New York. The syndrome has rapidly spread since then. In early 2018, it was identified in 33 U.S. states and seven Canadian provinces; plus the fungus, albeit sans syndrome, had been found in three additional states. Most cases are in the eastern half of both countries, but in March 2016, it was confirmed in a little brown bat in Washington state. In 2019, evidence of the fungus was detected in California for the first time, although no affected bats were found. The disease is caused by the fungus ''Pseudogymnoascus destructans'', which colonizes the bat's skin. No obviou ... [...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. History The Speleological Society of the District of Columbia (SSDC) was formed on May 6, 1939 by Bill Stephenson. In the fall of 1940, the officers of the SSDC drafted a proposed constitution that would transform the SSDC into the National Speleological Society. On January 24, 1941, Stephenson sent a letter to all members of the SSDC announcing that "on January 1 the Society was reorganized as a national organization." The New England Grotto was the first NSS Grotto. It was chartered in 1941 with Clay Perry as president and Ned Anderson as vice pr ...

Snowmelt
In hydrology, snowmelt is surface runoff produced from melting snow. It can also be used to describe the period or season during which such runoff is produced. Water produced by snowmelt is an important part of the annual water cycle in many parts of the world, in some cases contributing high fractions of the annual runoff in a watershed. Predicting snowmelt runoff from a drainage basin may be a part of designing water control projects. Rapid snowmelt can cause flooding. If the snowmelt is then frozen, very dangerous conditions and accidents can occur, introducing the need for salt to melt the ice. Energy fluxes related to snowmelt There are several energy fluxes involved in the melting of snow. These fluxes can act in opposing directions, that is either delivering heat to or removing heat from the snowpack. Ground heat flux is the energy delivered to the snowpack from the soil below by conduction. Radiation inputs to the snowpack include net shortwave (solar radiation including ...

Fringed Myotis
The fringed myotis (''Myotis thysanodes'') is a species of vesper bat that is found in British Columbia, Mexico, and the western United States. Description ''Myotis thysanodes,'' or the fringed myotis, has the shortest ears of the long-eared myotis group. The fringed myotis gets its name from the distinct fringe of short, wire-like hairs found on the membrane between its hind legs. With a lifespan that can reach upwards of 18 years, this species has an average total body length of roughly 85mm and an average weight of 8.8 grams.Schmidly, D. 1991. ''Bats of Texas''. College Station:Texas A&M University Press. Ear length is about 16.5mm and they project roughly 5mm beyond its snout.

Caves Of Wyoming
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 ...

Protected Areas Of Sheridan County, Wyoming
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage serving ...
