Description

Caving, also known as spelunking, is primarily a recreational sport that consists of the exploration of caves by hobbyist. The recreational form of spelunking is enjoyed by all ages and both genders. Caves have been explored for thousands of years. Evidence suggests that prehistoric men ventured into caves for shelter and protection rather than for recreation.

Besides being a recreation, caving is often used by scientist and geologist to study the interior formations of the earth such as stalactites and stalagmites. The interior view of the caves gives scientist clues as to how the earth was formed. Also studied are the numerous animals that can be found in the dark recesses. A person who studies caves from a scientific point of view is known as a Speleologist.

Cavers can venture into caves in the ground, in the ice, and caves that are submerged underwater. The ground caver utilizes equipment such as flashlights, ropes, helmets, gloves, knee pads, and waterproof gear to assist them in their exploration. The ice cavers utilizes ice climing equipment as well as traditional ground caving equipment. The underwater caver utilizes specialized equipment that includes scuba gear to assist in breathing.

Cave Formations

Caves are formed in several different ways. A few of the most common are listed below.

The most common cave formation is called the solutional cave. This type of cave is formed as water soaks into the ground and accumulates at depths below the surface. The water disolves the surrounding ground and forms the cave. As the amount of water increases, the size of the cave will also increase.

Lava caves are formed during volcanic eruption. Lava tubes are formed after the surface of the lava cools leaving a roof over the tubes. Eventually the hot lava will flow out of the tube leaving the hollow core of the cave.

Sea caves are formed by the ocean waves eroding rock away from the face of a cliff.

Sandstone caves are formed when rock and wind erode material away fomr the face of a mountain.

Ice caves are formed by melting glaciers. The water runs into the cracks a crevices of the glacier and accumulates. While the water melts, it erodes a cave along its path.
