Snow Cornice
A snow cornice or simply cornice (from the Italian cornice meaning "ledge") is an overhanging edge of snow on a ridge or the crest of a mountain and along the sides of gullies. Formation A snow cornice forms by wind blowing snow over sharp terrain breaks (e.g. the crest of the mountain) where it attaches and builds out horizontally. This build-up is most common on the steeper and leeward sides of mountains. Cornices are extremely dangerous and travelling above or below them should be avoided. When a cornice ''collapses'', it breaks in from the cornice to the top of the peak; even being on the snow on top of rock exposes the alpinist to hazard in this situation. The best practice in mountaineering is to stay far enough back from the edge so as not to be able to see the drop, as an approximate metric of exposure. Interview und Bilder zum Unglück In avalanche safety, cornices are a high avalanche danger as they often break and trigger larger avalanches that permeate several sno ...

Mont Blanc
Mont Blanc (, ) is a mountain in the Alps, rising above sea level, located right at the Franco-Italian border. It is the highest mountain in Europe outside the Caucasus Mountains, the second-most prominent mountain in Europe (after Mount Elbrus in Russia), and the 11th most prominent mountain in the world. The mountain gives its name to its range, the Mont Blanc massif, which straddles parts of France, Italy, and Switzerland. Mont Blanc's summit lies on the watershed line between the valleys of Ferret and Veny in Italy, and the valleys of Montjoie, and Arve in France. Ownership of the summit area has long been disputed between France and Italy. The Mont Blanc massif is popular for outdoor activities such as hiking, climbing, and trail running and winter sports such as skiing and snowboarding. The most popular climbing route to the summit of Mont Blanc is the Goûter Route, which typically takes two days. The three towns and their communes which surround Mont Bla ...

Sastrugi
Sastrugi, or zastrugi, are features formed by the erosion of snow by wind. They are found in polar regions, and in snowy, wind-swept areas of temperate regions, such as frozen lakes or mountain ridges. Sastrugi are distinguished by upwind-facing points, resembling anvils, which move downwind as the surface erodes. These points usually lie along ridges parallel to the prevailing wind; they are steep on the windward side and sloping to the leeward side. Smaller irregularities of this type are known as ripples (small, ~10 mm high) or wind ridges. Large sastrugi are troublesome to skiers and snowboarders. Traveling on the irregular surface of sastrugi can be very tiring and can risk breaking equipment; ripples and waves are often undercut, and the surface is hard and unforgiving, with constant minor topographic changes between ridge and trough. Etymology The words ''sastrugi'' and ''zastrugi'' are Russian-language plurals; the singular is ''zastruga''. The form ''sastruga'' ...

Andes
The Andes ( ), Andes Mountains or Andean Mountain Range (; ) are the List of longest mountain chains on Earth, longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long and wide (widest between 18th parallel south, 18°S and 20th parallel south, 20°S latitude) and has an average height of about . The Andes extend from south to north through seven South American countries: Argentina, Chile, Bolivia, Peru, Ecuador, Colombia, and Venezuela. Along their length, the Andes are split into several ranges, separated by intermediate depression (geology), depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, Mérida, Mérida, El Alto, and La Paz. The Altiplano, Altiplano Plateau is the world's second highest after the Tibetan Plateau. These ranges are in turn grouped into three majo ...

Siula Grande
Siula Grande is a mountain in the Huayhuash mountain range in the Peruvian Andes. It is high and has a subpeak, Siula Chico, high. __NOTOC__ ''Touching the Void'' ascent In 1985, Siula Grande was climbed by Joe Simpson and Simon Yates. Although they ascended the West face, and thereby became the first to reach the summit by that route, they chose to descend the North Ridge, the route of the first ascent and descent in 1936. This was made almost impossible by severe weather which caused Simpson to fall and severely break his leg. All subsequent west face climbers have avoided the ridge and rappelled down the face. Simpson and Yates's ascent was described in Simpson's book '' Touching the Void''. The book was made into a film of the same title in 2003 and a play in 2018.

Snow
Snow consists of 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 Sublimation (phase transition), sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes Nucleation, nucleate around particles in the atmosphere by attracting supercooling, supercooled water droplets, which Freezing, freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns, and Hard rime, rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Jacinto Peak
San Jacinto Peak ( ; often designated Mount San Jacinto) is a peak in the San Jacinto Mountains, in Riverside County, California. Lying within Mount San Jacinto State Park it is the highest both in the range and the county, and serves as the southern border of the San Gorgonio Pass. San Jacinto Peak is one of the most topographic prominence, topographically prominent peaks in the United States, and is ranked the sixth most prominent peak in the contiguous United States, 48 contiguous states. According to John W. Robinson and Bruce D. Risher, authors of ''The San Jacintos,'' "No Southern California hiker worth his salt would miss climbing 'San Jack' at least once." Known for its spectacular north escarpment, the peak rises over above San Gorgonio Pass. It plays host to the famous Cactus to Clouds Trail. Geography To the east of San Jacinto, the peak towers over the city of Palm Springs, California, Palm Springs (elevation 479 ft; 146 m); to the west, it borders the ...

Solar Irradiance
Solar irradiance is the power per unit area (surface power density) received from the Sun in the form of electromagnetic radiation in the wavelength range of the measuring instrument. Solar irradiance is measured in watts per square metre (W/m2) in SI units. Solar irradiance is often integrated over a given time period in order to report the radiant energy emitted into the surrounding environment (joule per square metre, J/m2) during that time period. This integrated solar irradiance is called solar irradiation, solar radiation, solar exposure, solar insolation, or insolation. Irradiance may be measured in space or at the Earth's surface after atmospheric absorption and scattering. Irradiance in space is a function of distance from the Sun, the solar cycle, and cross-cycle changes.Michael Boxwell, ''Solar Electricity Handbook: A Simple, Practical Guide to Solar Energy'' (2012), pp. 41–42. Irradiance on the Earth's surface additionally depends on the tilt of the measuri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
