Avalanche Cord
{{Short description, Locating device for people who have been buried by an avalanche An avalanche cord (german: Lawinenschnur) is an old form of person locating device designed to enable people who have been buried by an avalanche to be rapidly located and rescued. Function An avalanche cord is 20-25 metres long and about 3.5 mm thick. It is usually made of red cotton with direction arrows positioned at metre intervals, each with the length marked in metres, and 10 cm long loops. It is wound into a ball. The ski mountaineer or climber ties the loop with the 1-metre mark (arrow against himself) around his waist. If there is a risk of avalanches he throws the ball out and pulls the avalanche cord along the snow behind him. If he is buried by an avalanche, there is a relatively good chance that part of the avalanche cord will be visible on top of the avalanche slide, thanks to its length. Rescuers can determine from the direction arrows, in which direction and how many metres they mu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Avalanche
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 movement ...

Ski Mountaineer
Ski mountaineering (abbreviated to skimo) 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. Competitive ski mountaineering is typically a timed racing event that follows an established trail through challenging winter alpine terrain while passing through a series of checkpoints. Racers climb and descend under their own power using backcountry skiing equipment and techniques. More generally, ski mountaineering is an activity that variously combines ski touring, Telemark, backcountry skiing, and mountaineering. History Military patrol was an official event at the 1924 Winter Olympics, followed by demonstration events at the 1928 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpine Companies
The Alpine companies (german: Hochgebirgskompanien) were specialized mountain infantry troops that were part of the Austro-Hungarian land forces during the First World War. History Because normal forces could not be employed on reconnaissance and combat tasks in the high mountains of the Alps, in 1916 Alpine ''Streif'' companies (''Streifkompanien'') were established. They were renamed in 1917 to ''Hochgebirgskompanien'' ("Alpine companies" or, literally "high mountain companies"). The members of these companies represented all the ethnic groups of the monarchy together. They all had previous Alpine experience, either as a result of their agricultural experience or as Alpine tourists before the war, and were specifically trained for fighting in the mountains. The specially selected officers and men of the mountain companies were issued with Alpine equipment, and were intended, and in practice were able, to overcome natural obstacles even in the most difficult terrain.

First World War
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Italian Front (World War I)
The Italian front or Alpine front ( it, Fronte alpino, "Alpine front"; in german: Gebirgskrieg, "Mountain war") involved a series of battles at the border between Austria-Hungary and Italy, fought between 1915 and 1918 in the course of World War I. Following secret promises made by the Allies in the 1915 Treaty of London, Italy entered the war aiming to annex the Austrian Littoral, northern Dalmatia, and the territories of present-day Trentino and South Tyrol. Although Italy had hoped to gain the territories with a surprise offensive, the front soon bogged down into trench warfare, similar to that on the Western Front in France, but at high altitudes and with very cold winters. Fighting along the front displaced much of the local population, and several thousand civilians died from malnutrition and illness in Italian and Austro-Hungarian refugee-camps. The Allied victory at Vittorio Veneto, the disintegration of the Habsburg empire, and the Italian capture of Trento and Tri ...

Avalanche Transceiver
An avalanche transceiver or avalanche beacon is a type of emergency locator beacon, a radio transceiver (a transmitter and receiver in one unit) operating at 457 kHz for the purpose of finding people buried under snow. They are widely carried by skiers, particularly back country skiers for use in case a skier is buried by an avalanche. Before setting out on an expedition, all the members of a group activate their transceivers in the transmit mode, causing the device to emit low-power pulsed radio signals during the trip. Following an avalanche, if some members of the ski party are buried, the others may switch their transceivers from transmit into receive mode, allowing use as a radio direction finding device to search for signals coming from the lost skiers. The avalanche beacon is an active device powered by batteries; a ski suit may also contain a passive RECCO transponder sewn into the clothing. Early avalanche transceivers transmitted at 2.275 kHz. In 1986, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
