Cave

A cave or cavern is a hollow place in the ground, especially a natural underground space large enough for a human to enter. Caves form naturally by the weathering of rock and often extend deep underground. The word cave can also refer to much smaller openings such as sea caves, rock shelters, and grottos.

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.

Types and formation

The formation and development of caves is known as speleogenesis. Caves are formed by various geologic processes and can be variable sizes. These may involve a combination of chemical processes, erosion from water, tectonic forces, microorganisms, pressure, and atmospheric influences.

It is estimated that the maximum depth of a cave cannot be more than 3,000 metres (9,800 ft) due to the pressure of overlying rocks. For karst caves the maximum depth is determined on the basis of the lower limit of karst forming processes, coinciding with the base of the soluble carbonate rocks.

Cave, Lazio

History

The town was mentioned first in 998 AD, and was later a fief of the Colonna family. In 1482 it was besieged by Pope Sixtus IV and obliged to surrender.

    Plot

    Alfred is a young boy staying in a hospital who suffers from an undisclosed terminal illness. Enzo, a janitor at the hospital, meets Alfred while working and the two develop a friendship. Enzo tells Alfred of Helium, an attractive alternative to Heaven, because Alfred imagines Heaven is very boring. Enzo tells Alfred that to get to Helium, he will fly in an airship that will know to pick him up because of his red balloon dog, which Enzo has made for him.

    Alfred's illness worsens, and he is moved to a unit to which Enzo doesn’t have access. Enzo sneaks onto the unit, but is caught by the head nurse and barred from seeing Alfred. As Alfred's condition worsens, Enzo wonders if he is making it worse for the boy. He voices these concerns to a nurse saying, “I’m feeding him lies.” She disagrees and tells Enzo “you’re giving him hope.”

    Alfred gets worse, and having no access to him, Enzo writes out “the end of the story” to have the nurse read to him. As the nurse is about to read the ending to a dying Alfred, she changes her mind and, instead, sneaks Enzo onto the unit to tell the rest himself.

    Helium (band)

    Helium was an American alternative rock band formed during the summer of 1992. Under the original moniker of "Chupa," the band's founding members were Mary Lou Lord; Jason Hatfield, Juliana Hatfield's brother; Shawn King Devlin; and Brian Dunton. Devlin and Dunton were both also in the band Dumptruck before founding Helium.

    History

    Mary Timony, formerly of the band Autoclave, replaced Mary Lou Lord on vocals and guitar shortly after formation, as Lord was reluctant to use electric instrumentation. Following Lord's departure, the remaining members changed the band's name to Helium.

    As Helium's second frontperson, Timony incorporated a Lolita-esque image with the band, with short schoolgirl skirts, an accompanying hairstyle, and naughty lyrics. Timony was also known for her husky, vibrato-less and monotone singing style. The band's record label, Matador Records, likened Timony's vocals to Kim Wilde and Debbie Harry.

    Releases

    Their first release was a 7" single entitled "The American Jean" (1993), which was followed by the 7" "Hole in the Ground". They released their first EP, Pirate Prude, in 1994. Shortly after the release of Pirate Prude, Dunton left the band and Polvo guitarist Ash Bowie, boyfriend of Timony at the time, joined on bass. In 1995, they released their first full-length release, The Dirt of Luck, and played the second stage of Lollapalooza. Adam Lasus produced and engineered The Dirt of Luck, Pirate Prude, and all of Helium's singles up to 1995.
