Mountaineering, mountain climbing, or alpinism is a set of outdoor activities that involves ascending mountains. Mountaineering-related activities include traditional outdoor climbing, skiing, and traversing via ferratas that have become sports in their own right. Indoor climbing, sport climbing, and bouldering are also considered variants of mountaineering by some, but are part of a wide group of mountain sports.
A crampon is a traction device attached to footwear to improve mobility on snow and ice during ice climbing. Besides ice climbing, crampons are also used for secure travel on snow and ice, such as crossing glaciers, snowfields and icefields, ascending snow slopes, and scaling ice-covered rock.
Glossary of climbing terms relates to rock climbing, mountaineering, and to ice climbing.
Ice climbing is a climbing discipline that involves ascending routes consisting of frozen water. To ascend, the ice climber uses specialist equipment, particularly double ice axes and rigid crampons. To protect the route, the ice climber uses steel ice screws that require skill to employ safely and rely on the ice holding firm in any fall. Ice climbing routes can vary significantly by type, and include seasonally frozen waterfalls, high permanently frozen alpine couloirs, and large hanging icicles.
Abseiling, also known as rappelling, is the controlled descent of a steep slope, such as a rock face, by moving down a rope. When abseiling, the person descending controls their own movement down a static or fixed rope, in contrast to lowering off, in which the rope attached to the person descending is paid out by their belayer.
Ski mountaineering is a skiing discipline that involves climbing mountains either on skis or carrying them, depending on the steepness of the ascent, and then descending on skis. There are two major categories of equipment used, free-heel Telemark skis and skis based on Alpine skis, where the heel is free for ascents, but is fixed during descent. The discipline may be practiced recreationally or as a competitive sport.
In climbing, a pitch is a section of a climbing route between two belay points, and is most commonly related to the task of lead climbing, but is also related to abseiling. Climbing on routes that require only one pitch is known as single-pitch climbing, and climbing on routes with more than one pitch is known as multi-pitch climbing.
Mount Moran is a mountain in Grand Teton National Park of western Wyoming, USA. The mountain is named for Thomas Moran, an American western frontier landscape artist. Mount Moran dominates the northern section of the Teton Range rising 6,000 feet (1,800 m) above Jackson Lake. Several active glaciers exist on the mountain with Skillet Glacier plainly visible on the monolithic east face. Like the Middle Teton in the same range, Mount Moran's face is marked by a distinctive basalt intrusion known as the Black Dike.
An ascender is a device used for directly ascending, or for facilitating protection, with a fixed rope when climbing on steep mountain terrain. A form introduced in the 1950s became so popular it began the term "Jumar" for the device, and the verb "to jumar" to describe its use in ascending.
The self-arrest is a climbing technique mostly used in mountaineering and alpine climbing where a climber who has fallen and is sliding uncontrollably down a snow or ice-covered slope 'arrests' their fall by themselves by using their ice axe and their crampons.
A Prusik is a friction hitch or knot used to attach a loop of cord around a rope, applied in climbing, canyoneering, mountaineering, caving, rope rescue, ziplining, and by arborists. The term Prusik is a name for both the loops of cord used to tie the hitch and the hitch itself, and the verb is "to prusik" or "prusiking". More casually, the term is used for any friction hitch or device that can grab a rope. Due to the pronunciation, the word is often misspelled Prussik, Prussick, or Prussic.
Oscar Johannes Ludwig Eckenstein was an English rock climber and mountaineer, and a pioneer in the sport of bouldering. Inventor of the modern crampon, he was an innovator in climbing technique and mountaineering equipment, and the leader of the first serious expedition to attempt K2.
In rock climbing, an anchor can be any device or method for attaching a climber, rope, or load to a climbing surface—typically rock, ice, steep dirt, or a building—either permanently or temporarily. The intention of an anchor is case-specific but is usually for fall protection, primarily fall arrest and fall restraint. Climbing anchors are also used for hoisting, holding static loads, or redirecting a rope.
Peter Kittilsby Schoening was an American mountaineer. Schoening was one of two Americans to first successfully climb the Pakistani peak Gasherbrum I in 1958, along with Andrew Kauffman, and was one of the first to summit Mount Vinson in Antarctica in 1966.
An ice screw is a threaded tubular screw used as a running belay or anchor by climbers on steep ice surface such as steep waterfall ice or alpine ice during ice climbing or crevasse rescue, to hold the climber in the event of a fall, and at belays as anchor points.
An ice tool is a specialized elaboration of the modern ice axe, used in ice climbing, mostly for the more difficult configurations. Ice tools are used two to a person for the duration of a pitch, and thus in some circumstances such as top-rope-anchored climbs, a pair may be shared among two or more people, where only one of them at a time is climbing. In contrast a classical "ice axe" is used one to a person for the hours or days a party is traveling across snow or glacier. In communities where it is common to refer to an "ice tool" simply as an "ice axe", classic "ice axes" are often referred to as "traveling axes", "walking axes", or "general mountaineering axes" to distinguish them from "tools".
A hex is an item of rock-climbing equipment used to protect climbers from falls. They are intended to be wedged into a crack or other opening in the rock, and do not require a hammer to place. They were developed as an alternative to pitons, which are hammered into cracks, damaging the rock. Most commonly, a carabiner will be used to join the hex to the climbing rope by means of a loop of webbing, cord or a cable which is part of the hex.
The 1953 American Karakoram expedition was a mountaineering expedition to K2, at 8,611 metres the second highest mountain on Earth. It was the fifth expedition to attempt K2, and the first since the Second World War. Led by Charles Houston, a mainly American team attempted the mountain's South-East Spur in a style which was unusually lightweight for the time. The team reached a high point of 7750 m, but were trapped by a storm in their high camp, where a team member, Art Gilkey, became seriously ill. A desperate retreat down the mountain followed, during which all but one of the climbers were nearly killed in a fall arrested by Pete Schoening, and Gilkey later died in an apparent avalanche. The expedition has been widely praised for the courage shown by the climbers in their attempt to save Gilkey, and for the team spirit and the bonds of friendship it fostered.
Mixed climbing is a climbing discipline used on routes that do not have enough ice to be pure ice climbs, but are also not dry enough to be pure rock climbs. To ascend the route, the mixed climber uses ice climbing equipment, but to protect the route, they use both rock-climbing equipment and ice climbing equipment. Mixed climbing varies from routes with sections of thick layers of ice and sections of bare rock, to routes that are mostly bare rock but which are "iced-up" in a thin layer of ice and/or snow.
An alpenstock is a long wooden pole with an iron spike tip, used by shepherds for travel on snowfields and glaciers in the Alps since the Middle Ages. It is the antecedent of the modern ice axe.
