Caving
From Wikipedia, the free encyclopedia
Caving is the recreational sport of exploring caves. Speleology is the scientific study of caves and the cave environment.
The challenges of the sport depend on the cave being visited, but often include the negotiation of pitches, squeezes, and water. Climbing or crawling is often necessary, and ropes are used extensively.
Caving is often undertaken for the enjoyment of the activity or for physical exercise, but original exploration, or physical or biological science is an important goal for many cavers. Virgin cave systems comprise some of the last unexplored regions on Earth and much effort is put into trying to locate and enter them. In well-explored regions (such as most first-world countries), the most accessible caves have already been explored, and gaining new caves often requires digging or diving.
Caves have been explored out of necessity for thousands of years, but only in the last century or two has the activity become a sport. In recent decades caving has changed considerably due to the availability of modern protective wear and equipment. It has recently come to be known as an "extreme sport" by some (though not commonly considered as such by its practitioners, who may dislike the term for its perceived connotation of disregard for safety.)
Many of the skills of caving can also be used in the sports of mine exploration and urban exploration.

[edit] Naming issues
Clay Perry — an American caver of the 1940s — wrote about a group of men and boys who explored and studied caves throughout New England. This group referred to themselves as spelunkers. This is regarded as the first use of the word in the Americas. Throughout the 1950s, spelunking was the general term used for exploring caves in US English. It was used freely, without any positive or negative connotations, although only rarely outside the US.
In the 1960s, the term "spelunking" began to convey the idea of inexperienced cavers, using unreliable light sources and cotton clothing. In 1985, Steve Knutson (editor of American Caving Accidents) made the following distinction:
- "...Note that I use the term 'spelunker' to denote someone untrained and unknowledgeable in current exploration techniques, and 'caver' for those who are."
This sentiment is exemplified by bumper stickers and t-shirts displayed by many cavers: "Cavers rescue spelunkers".
Potholing refers to the act of exploring potholes, a word originating in the north of England for predominantly vertical caves. The term is often used as a synonym for caving, and outside the caving world there is a general impression that potholing is a more "extreme" version of caving.
[edit] Practice and equipment
Helmets are worn to protect the head from bumps and falling rocks. The caver's primary light source is usually mounted on the helmet in order to keep the hands free. Electric lights are most common, with halogen lamps being standard and white LEDs as the new competing technology. Many cavers carry two sources of light - one as primary and the other as a backup in case the first fails. Carbide-based systems are still popular, especially on expeditions. Spare flashlights are often kept, but it is not recommended to use anything bigger than a mini-mag (a very small version of the popular Maglite flashlight).
The type of clothes worn underground varies according to the environment of the cave being explored, and the local culture. In cold caves, the caver may wear a warm base layer that retains its insulating properties when wet, such as a fleece ("furry") suit and/or polypropylene underwear, and an oversuit of hard-wearing (e.g., cordura) and/or waterproof (e.g., PVC) material. Lighter clothing may be worn in warm caves, particularly if the cave is dry, and in tropical caves thin polypropylene clothing is used, to provide some abrasion protection whilst remaining as cool as possible. Wetsuits may be worn if the cave is particularly wet or involves stream passages. On the feet boots are worn - hiking-style boots in drier caves, or rubber boots (such as wellies) often with neoprene socks ("wetsocks") in wetter caves. Knee-pads (and sometimes elbow-pads) are popular for protecting joints during crawls. Gloves are almost always worn.
Ropes are used for descending or ascending pitches ("Single Rope Technique") or for protection. Knots commonly used in caving are the figure-of-eight- (or figure-of-nine-) loop, bowline, alpine butterfly, and Italian hitch. Ropes are usually rigged using bolts, slings, and carabiners.
Cavers carry packs filled with first-aid kits, food, extra equipment and bathroom supplies. So-called "pee bottles" are now standard and cavers are expected to carry their waste out with them. For solid waste, several zip-lock type bags (one inside the other) are used, surrounded by aluminum foil (for aesthetic reasons). These are affectionally referred to as "cave burritos".
[edit] Safety
Caves can be dangerous places; hypothermia, falling, flooding, and physical exhaustion are the main risks. Rescue from underground is difficult and time-consuming, and requires special skills, training, and equipment. Full-scale cave rescues often involve the efforts of dozens of rescue workers, who may themselves be put in jeopardy in effecting the rescue. This said, caving is not necessarily a high-risk sport (especially if it does not involve difficult climbs or diving). As in all physical sports, knowing one's limitations is key.
The risks are minimised by a number of techniques:
- Checking that there is no danger of flooding during the expedition. Rainwater funneled underground can flood a cave very quickly while the surface remains clear.
- Using teams of at least four cavers. (If an injury occurs, one caver stays with the injured person while the other two go for help.)
- Having a "call-out person" who will notify appropriate rescue personnel if the party does not return by a predetermined time.
- Use of helmet-mounted lights with extra batteries. American cavers always recommend a minimum of three independent sources of light per person, but two lights is common practice amongst European cavers.
- Sturdy clothing and footwear, as well as a helmet, are necessary to reduce the impact of abrasions, caver falls, and falling objects. Synthetic fibers and woolens, which dry quickly, shed water, and are warm when wet, are vastly preferred to cotton materials, which retain water and increase the risk of hypothermia. It is also helpful to have several layers of clothing, which can be shed (and stored in the pack) or added as needed. In watery cave passages, partial or full wetsuits reduce the risk of hypothermia.
- Cave passages look different from different directions. In long or complex caves, even experienced cavers become lost. To reduce the risk of becoming lost, it is necessary to memorize the appearance of key navigational points in the cave as they are passed by the exploring party. Each member of a cave party shares responsibility for being able to remember the route out of the cave. In some caves it may be acceptable to mark a small number of key junctions with small stacks or "cairns" of rocks, or to leave a non-permanent mark such as high-visibility flagging tape tied to a projection.
- Vertical caving involves ladders or SRT (Single Rope Technique). SRT is a complex skill and requires proper training before trying it underground.
[edit] Cave conservation
Many cave environments are very fragile; since water that flows through a cave eventually comes out in streams and rivers, any pollution may ultimately end up in someone's drinking water, and can even seriously affect the surface environment, as well.
Cave-dwelling species are also very fragile, and often, a particular species found in a cave may live within that cave alone, and be found nowhere else in the world. Cave-dwelling species are accustomed to a near-constant climate of temperature and humidity, and any disturbance can be disruptive to the species' life cycles. Though cave wildlife may not always be immediately visible, it is typically nonetheless present in most caves.
Bats are one such fragile species of cave-dwelling animal. Despite their often frightening reputation in fiction and in the movies, bats generally have more to fear from humans than vice-versa. Bats can be beneficial to humans in many ways, especially through their important ecological role in reducing insect pest populations, and pollenization of plant species. Bats are most vulnerable during the winter hibernation season, when no food supply exists on the surface to replenish the bat's store of energy should it be awakened from hibernation. For this reason, visiting bat-inhabited caves during cold months, when bats are most sensitive and vulnerable, is discouraged.
Some cave passages may be marked with flagging tape or other indicators to show biologically, aesthetically, or archaeologically sensitive areas. Marked paths may be notably fragile; a pristine floor of sand or silt may be thousands of years old, dating from the last time water flowed through the cave. Such deposits may easily be spoiled forever by a single misplaced step. Active formations such as flowstone can be similarly marred with a muddy footprint or handprint, and ancient human artifacts, such as fiber products, may even crumble to dust under the touch of any but the most careful archaeologist.
