Glissade (climbing)
Glissading is the act of descending a steep snow- or scree-covered slope via a controlled slide on one's feet or buttocks. It is an alternative to other descent methods such as plunge stepping, and may be used to expedite a descent, or simply for the thrill. Glissading involves higher risks of injuries than other forms of descending. Glissading with crampons is especially dangerous and should never be attempted. "The Mt. Shasta rangers constantly stress that climbers never should glissade while wearing crampons. Regardless, a few slip through the cracks. Double broken ankles should teach a powerful lesson." Methods There are three primary methods of glissading: * Sitting * Standing * Crouching Sitting glissade This is the easiest type of glissade and generally provides the greatest amount of stability. It is also less tiring than a standing or crouching glissade in softer snow. To perform a sitting glissade one sits down and slides on the slope usually holding on to an ice ax ...

Snow
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scree
Scree is a collection of broken rock fragments at the base of a cliff or other steep rocky mass that has accumulated through periodic rockfall. Landforms associated with these materials are often called talus deposits. Talus deposits typically have a concave upwards form, where the maximum inclination corresponds to the angle of repose of the mean debris particle size. The exact definition of scree in the primary literature is somewhat relaxed, and it often overlaps with both ''talus'' and ''colluvium''. The term ''scree'' comes from the Old Norse term for landslide, ''skriða'', while the term ''talus'' is a French word meaning a slope or embankment. In high-altitude arctic and subarctic regions, scree slopes and talus deposits are typically adjacent to hills and river valleys. These steep slopes usually originate from late-Pleistocene periglacial processes. Notable scree sites in Eastern North America include the Ice Caves at White Rocks National Recreation Area in southern Ve ...

Backpacker (magazine)
''Backpacker'' is an American lifestyle magazine publication that features information on wilderness hiking and adventure. It has been published since 1973. ''Backpacker'' magazine is currently published by '' Outside'' and is based in Boulder, Colorado. Originally started in Bedford Hills, New York, the magazine moved to Emmaus, Pennsylvania in the late 1980s and then to Boulder in August 2007. History The first issue of ''Backpacker'' appeared in the spring of 1973. The first editor's note written by William Kemsley, the founding editor, explains that it took three years to put together the first issue of ''Backpacker,'' and that the founding editors worried that America in the early 1970s did not contain a backpacking community large enough to support a magazine. It also expresses Kemsley's goal to support the magazine primarily through subscriptions rather than advertising. The Winter/Spring 2007 issue of the journal ''Appalachia'' includes an essay by Kemsley titled "How th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crampons
A crampon is a traction device that is 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. There are three main attachment systems for footwear: step-in, hybrid, and strap bindings. The first two require boots with welts, or specialized mountaineering boots with dedicated front and rear lugs, as a cam-action lever attaches the crampon to the heel. The last type (strap bindings) are more versatile and can adapt to virtually any boot or shoe, but often do not fit as precisely as the other two types. Oscar Eckenstein designed the first 10-point crampon in 1908, dramatically reducing the need for step cutting. This design was then made commercially available by the Italian Henry Grivel. Characteristics Materials Crampons are made of steel alloy, light weight alumi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ice Axe
An ice axe is a multi-purpose hiking and climbing tool used by mountaineers in both the ascent and descent of routes that involve snow, ice, or frozen conditions. Its use depends on the terrain: in its simplest role it is used like a walking stick, with the mountaineer holding the head in the center of their uphill hand. On steep terrain it is swung by its handle and embedded in snow or ice for security and an aid to traction. It can also be buried pick down, the rope tied around the shaft to form a secure anchor on which to bring up a second climber, or buried vertically to form a stomp belay. The adze is used to cut footholds, as well as scoop out compacted snow to bury the axe as a belay anchor. History The ice axe of today has its roots in the long-handled alpenstock that came before it. Not only is an ice axe used as a climbing aid, but also as a means of self-arrest in the event of a slip downhill. Most ice axes meet design and manufacturing standards of organizati ...

Self-arrest
Self-arrest is a technique employed in mountaineering in which a climber who has fallen and is sliding down a snow or ice-covered slope arrests the slide by themselves without recourse to a rope or other belay system. Self-arrest can be performed by using ice axe and a combination of a climber's boots, hands, feet, knees and elbows. Use of an ice axe greatly increases the probability of effectively stopping a fall down a snow field, ice field, or glacier. Techniques Widely used self-arrest techniques involve placing one's body weight on top of an ice axe to drive the head into the slope. Lack of an ice axe reduces the probability of successful self-arrest. Effectiveness The likelihood of being able to self-arrest depends on skills of the climber and three main factors: * Angle of the slope: The greater the angle of the slope, the harder it is to arrest a slide. On very steep slopes, the chance of effective self-arrest may approach zero. * Hardness of the slope: The harder the su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ann Demonstrating Glissading On McBride Peak (7669616726)
Anne, alternatively spelled Ann, is a form of the Latin female given name Anna. This in turn is a representation of the Hebrew Hannah, which means 'favour' or 'grace'. Related names include Annie. Anne is sometimes used as a male name in the Netherlands, particularly in the Frisian speaking part (for example, author Anne de Vries). In this incarnation, it is related to Germanic arn-names and means 'eagle'.See entry on "Anne" in th''Behind the Name'' databaseand th"Anne"an"Ane"entries (in Dutch) in the Nederlandse Voornamenbank (Dutch First Names Database) of the Meertens Instituut (23 October 2018).

The Freedom Of The Hills
''Mountaineering: The Freedom of the Hills'' is often considered the standard textbook for mountaineering and climbing in North America. The book was first published in 1960 by The Mountaineers of Seattle, Washington. The book was written by a team of over 40 experts in the field. The book grew out of the annual climbing course run since 1935 by the Mountaineers, for which the reading material was originally a combination of European works and lecturers' mimeo outlines. These were assembled into the ''Climber's Notebook'' and published by the Mountaineers as the hardbound ''Mountaineers Handbook'' in 1948. By 1955 the rapid postwar evolution of climbing techniques and tools had made the ''Handbook'' out of date, and the effort was begun to produce ''Freedom of the Hills''. Nearly 80 major contributors are credited in the first edition and were organized by a committee of 8 editors. The first four editions were only available in hardcover.
