Avalanche Rescue
Avalanche rescue involves locating and retrieving people who have been buried in avalanches. Prevention There are several ways to prevent avalanches and lessen their power and destruction. They are employed in areas where avalanches pose a significant threat to people, such as ski resorts and mountain towns, roads and railways. Explosives are used extensively to prevent avalanches, especially at ski resorts where other methods are often impractical. Explosive charges are used to trigger small avalanches before enough snow can build up to cause a large avalanche. Snow fences and light walls can be used to direct the placement of snow. Snow builds up around the fence, especially the side that faces the prevailing winds. Downwind of the fence, snow buildup is lessened. This is caused by the loss of snow at the fence that would have been deposited and the pickup of the snow that is already there by the wind, which was depleted of snow at the fence. When there is a sufficient d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avalanche Warning In Tuckerman
An avalanche is a rapid flow of snow down a slope, such as a hill or mountain. Avalanches can be set off spontaneously, by such factors as increased precipitation or snowpack weakening, or by external means such as humans, animals, and earthquakes. Primarily composed of flowing snow and air, large avalanches have the capability to capture and move ice, rocks, and trees. Avalanches occur in two general forms, or combinations thereof: slab avalanches made of tightly packed snow, triggered by a collapse of an underlying weak snow layer, and loose snow avalanches made of looser snow. After being set off, avalanches usually accelerate rapidly and grow in mass and volume as they capture more snow. If an avalanche moves fast enough, some of the snow may mix with the air, forming a powder snow avalanche. Though they appear to share similarities, avalanches are distinct from slush flows, mudslides, rock slides, and serac collapses. They are also different from large scale movements ...

Outside (magazine)
''Outside'' is an American company and magazine focused on the outdoors. The first issue of ''Outside'' was published in September 1977. History Outside founders were Jann Wenner (the first editor in chief), William Randolph Hearst III (its first managing editor), and Jack Ford (an assistant to founding publisher Donald Welsh and a son of former U.S. President Gerald Ford). Wenner sold ''Outside'' to Lawrence J. Burke two years later. Burke merged it into his magazine ''Mariah'' (founded in 1976) and after a period of using the name ''Mariah/Outside'' kept the ''Outside'' name for the merged magazine. Christopher Keyes is the current editor. Outside, formerly Pocket Outdoor Media, acquired Outside Integrated Media in February 2021. Outside brands include Outside Magazine, Outside Business Journal, Outside Integrated Media, Outside TV, Gaia GPS, fastestknowntime.com, athleteReg, Peloton Magazine, Yoga Journal, SKI, Backpacker, VeloNews, Climbing, Rock & Ice, Gym Climber, Trail ...

RECCO
The RECCO is a rescue technology used by organised rescue teams as an additional tool to more quickly locate people buried by an avalanche or lost in the outdoors. The system is based on a harmonic radar system and composed by a detector and a passive reflector integrated into outdoor clothing and gears. History The RECCO rescue technology was developed by Magnus Granhed, in response to his personal experience with a fatal avalanche accident in Åre, Sweden, in 1973. Starting in the winter of 1978–1979, Granhed collaborated with Bengt Enander's team at the Department of Electromagnetic Theory, Royal Institute of Technology in Stockholm to develop an avalanche rescue system, using the principle of harmonic radar. Granhed formed RECCO AB in 1983 and created the first functional prototype. In 1987, a woman was localised with the RECCO rescue technology from a helicopter in Lenzerheide, Switzerland, in the first live rescue found using the technology. In 2015, RECCO introduce ...

Ouray, Colorado
Ouray () is a home rule municipality that is the county seat of Ouray County, Colorado, United States. The city population was 1,000 as of the 2010 census. The Ouray Post Office has the ZIP Code 81427. Located at an elevation of , Ouray's climate, natural alpine environment, and scenery have earned it the nickname "Switzerland of America". History Originally established by miners seeking silver and gold in the surrounding mountains, the town at one time boasted more horses and mules than people. Prospectors arrived in the area in 1875. In 1877, William Weston and George Barber found the Gertrude and Una gold veins in Imogene Basin, six miles south southwest of Ouray. Thomas Walsh acquired the two veins and all the open ground nearby. In 1897, Walsh opened the Camp Bird Mine, adding a twenty-stamp mill in 1898, and a forty-stamp mill in 1899. The mine produced almost 200,000 ounces of gold by 1902, when Walsh sold out to Camp Bird, Ltd. By 1916, Camp Bird, Ltd., had produ ...

Backcountry Skiing
Backcountry skiing ( US), also called off-piste (Europe), alpine touring, or out-of-area, is skiing in the backcountry on unmarked or unpatrolled areas either inside or outside a ski resort's boundaries. This contrasts with alpine skiing, which is typically done on groomed trails benefiting from a ski patrol. Unlike ski touring, backcountry skiing can include the use of ski lifts including snowcats and helicopters. Recent improvements in equipment have increased the popularity of the sport. Terminology The terms "backcountry" and "off-piste" refer to where the skiing is being done, while terms like ski touring, ski mountaineering, telemark, freeriding, and extreme skiing describe what type of skiing is being done. Terms for backcountry skiing exist according to how the terrain is accessed, and how close it is to services. Backcountry can include the following: * Frontcountry: off-trail within ski area boundaries where ski lifts and emergency services are close at hand. * Slackc ...

Hypothermia
Hypothermia is defined as a body core temperature below in humans. Symptoms depend on the temperature. In mild hypothermia, there is shivering and mental confusion. In moderate hypothermia, shivering stops and confusion increases. In severe hypothermia, there may be hallucinations and paradoxical undressing, in which a person removes their clothing, as well as an increased risk of the heart stopping. Hypothermia has two main types of causes. It classically occurs from exposure to cold weather and cold water immersion. It may also occur from any condition that decreases heat production or increases heat loss. Commonly, this includes alcohol intoxication but may also include low blood sugar, anorexia and advanced age. Body temperature is usually maintained near a constant level of through thermoregulation. Efforts to increase body temperature involve shivering, increased voluntary activity, and putting on warmer clothing. Hypothermia may be diagnosed based on either a person ...

Physical Trauma
An injury is any physiological damage to living tissue caused by immediate physical stress. An injury can occur intentionally or unintentionally and may be caused by blunt trauma, penetrating trauma, burning, toxic exposure, asphyxiation, or overexertion. Injuries can occur in any part of the body, and different symptoms are associated with different injuries. Treatment of a major injury is typically carried out by a health professional and varies greatly depending on the nature of the injury. Traffic collisions are the most common cause of accidental injury and injury-related death among humans. Injuries are distinct from chronic conditions, psychological trauma, infections, or medical procedures, though injury can be a contributing factor to any of these. Several major health organizations have established systems for the classification and description of human injuries. Occurrence Injuries may be intentional or unintentional. Intentional injuries may be acts o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suffocation
Asphyxia or asphyxiation is a condition of deficient supply of oxygen to the body which arises from abnormal breathing. Asphyxia causes generalized hypoxia, which affects primarily the tissues and organs. There are many circumstances that can induce asphyxia, all of which are characterized by the inability of a person to acquire sufficient oxygen through breathing for an extended period of time. Asphyxia can cause coma or death. In 2015, about 9.8 million cases of unintentional suffocation occurred which resulted in 35,600 deaths. The word asphyxia is from Ancient Greek "without" and , "squeeze" (throb of heart). Causes Situations that can cause asphyxia include but are not limited to: airway obstruction, the constriction or obstruction of airways, such as from asthma, laryngospasm, or simple blockage from the presence of foreign materials; from being in environments where oxygen is not readily accessible: such as underwater, in a low oxygen atmosphere, or in a vacuum; envir ...
