Canyoning
Canyoning (also known as canyoneering) is traveling in canyons using a variety of techniques that may include walking, scrambling, climbing, jumping, abseiling, and/or swimming.
Although hiking down a canyon that is non-technical (canyon hiking) is often referred to as canyoneering, the terms canyoning and canyoneering are more often associated with technical descents — those that require rappels (abseils) and ropework, technical climbing or down-climbing, technical jumps, and/or technical swims.
Canyoning is frequently done in remote and rugged settings and often requires navigational, route-finding and other skills and preparation needed for wilderness travel.
Canyons that are ideal for canyoning are often cut into the bedrock stone, forming narrow gorges with numerous drops, beautifully sculpted walls, and sometimes spectacular waterfalls. Most canyons are cut into limestone, granite or sandstone, though other rock types are found. Canyons can be very easy or extremely difficult, though emphasis in the sport is usually on aesthetics and fun rather than pure difficulty. A wide variety of canyoning routes are found throughout the world, and canyoning is enjoyed by people of all ages and skill levels.
Canyoning gear includes climbing hardware, static ropes, helmets, wetsuits, and specially designed shoes, packs, and rope bags. While canyoners have used and adapted climbing, hiking, and river running gear for years, more and more specialized gear is invented and manufactured as canyoning popularity increases.
Canyoning around the world
In most parts of the world canyoning is done in mountain canyons with flowing water. Countries with established canyoning include: Australia, New Zealand, Spain, France, Ecuador, Japan, Italy, Switzerland, Germany, Austria, Reunion Island, Greece (Crete), Jordan, Canada, Mexico, Brazil, Croatia, Turkey, Israel and the United States. In South Africa, canyons that involve lots of jumping are common, and it is called Kloofing. Even in Hong Kong, where there are numerous stream gorges, a similar activity called stream or river trekking is popular. In Japan and Taiwan it's called river tracing and typically involves traveling upstream.
In the United States, descending mountain canyons with flowing water is often referred to as canyoning, and descending non-flowing (though often wet) desert canyons is referred to as canyoneering. Most canyoneering in the United States occurs in the many slot canyons carved in the sandstone found throughout the Colorado Plateau. Outside of the Colorado Plateau, numerous canyoning opportunities are found in the San Gabriel, Sierra Nevada, Cascade, and Rocky Mountain ranges.
Hazards
Canyoning can be dangerous. Escape out the sides of a canyon is often impossible, and completion of the descent is the only possibility. Due to the remoteness and inaccessibility of many canyons, rescue can be impossible for several hours or several days.
High water flow / hydraulics
Canyons with significant water flow may be treacherous and require special ropework techniques for safe travel. Hydraulics, undercurrents, and sieves (or strainers) occur in flowing canyons and can trap or pin and drown a canyoner. A 1993 accident in Zion National Park, Utah, USA, in which two leaders of a youth group drowned in powerful canyon hydraulics (and the lawsuit which followed) brought notoriety to the sport [1].
Flash floods
A potential danger of many canyoning trips is a flash flood. A canyon "flashes" when a large amount of precipitation falls in the drainage, and water levels in the canyon rise quickly as the runoff rushes down the canyon. In canyons that drain large areas, the rainfall could be many kilometers away from the canyoners, completely unbeknown to them. A calm or even dry canyon can quickly become a violent torrent due to a severe thunderstorm in the vicinity. [2] Fatalities have occurred as a result of flash floods; in one widely-publicized 1999 incident, a group of tourists on a commercial canyoning adventure trip drowned in Saxetenbach Gorge, Switzerland.
Hypothermia and hyperthermia
Temperature related illnesses are also canyoning hazards. In arid desert canyons, heat exhaustion can occur if proper hydration levels are not maintained and adequate steps are not taken to avoid the intense rays of the sun. Hypothermia can be a serious danger in any canyon that contains water, during anytime of the year. Wetsuits and drysuits can mitigate this danger to a large degree, but when people miscalculate the amount of water protection they will need, dangerous and sometimes fatal situations can occur. [3] Hypothermia due to inadequate cold water protection is sited as a cause of a 2005 incident in which two college students drowned in a remote Utah canyon. [4]
Keeper potholes
Some canyoneering, especially in sandstone slots, involves escaping from large potholes. Also called "keeper potholes," these features, carved out by falling water at the bottom of a drop in the watercourse, are circular pits that often contain water that is too deep to stand up in and whose walls are too smooth to easily climb out of. Canyoneers use several unique and creative devices to escape potholes, including hooks used for aid climbing attached to long poles and specialized weighted bags that are attached to ropes and tossed over the lip of a pothole.
Very narrow slots
Narrow slot canyons, especially those narrower than humans, present difficult obstacles for canyoners. At times a canyoner is forced to climb up (using chimneying or off-width climbing techniques) to a height where one can comfortably maneuver laterally with pressure on both walls of the canyon. This tends to be strenuous and can require climbing high above the canyon floor, unprotected, for long periods of time. Failure to complete the required moves could result in being trapped in a canyon where rescue is extremely difficult.
Narrow sandstone slot canyons tend have abrasive walls which act as sandpaper as a canyoner moves or slides along them. This abrasion tends to rip clothing and gear, and can cause painful skin abrasion.
