Wet Andes
file:Andes_clima.png, 200px, Map of the climatic regions of the Andes. The Wet Andes are shown in dark blue. The Dry Andes are shown in yellow and the Tropical Andes in green. The Wet Andes ( es, Andes húmedos) is a climatic and glaciology, glaciological subregion of the Andes. Together with the Dry Andes it is one of the two subregions of the Argentina, Argentine and Chilean Andes. The Wet Andes runs from a latitude of 35th parallel south, 35°S to Cape Horn at 56th parallel south, 56°S. According to Luis Lliboutry the Wet Andes can be classified after the absence of Penitente (snow formation), penitentes. In Argentina well developed penitentes are found as south as on Lanín Volcano (40th parallel south, 40°S). Another difference is that the Wet Andes is largely devoid of rock glaciers. The glaciers of the Wet Andes have a far more stable line of equilibrium than those of the Dry Andes due to summer precipitations, low thermal oscillations and an overall high moisture. Referen ...

Cardenal Antonio Samoré Pass
Cardenal Antonio Samoré Pass ( es, Paso Cardenal Antonio Samoré) is one of the main mountain passes through the southern Andes along the border between Argentina and Chile. Together with Paso Libertadores, it is one of the easiest of the Argentina-Chile passes, and one of the few with asphalted roads in the region. The main towns and cities respectively on both sides of the pass are Entre Lagos, Chile, Entre Lagos and Osorno, Chile, Osorno in Chile and Villa La Angostura and San Carlos de Bariloche in Argentina. From the Chilean side the pass is accessed through Route 215-CH, branch line which begins at the Chile Highway 5, Panamerican Highway in Osorno. On the Argentinian side the pass is reached by Ruta Nacional 231. Since 1974 there is a treaty that guarantee the transport of Chilean goods from the Chilean X Los Lagos Region to the XII Magallanes and Antártica Chilena Region over the Paso Samoré through the Argentinian Patagonia.ArticlDisputa con Chile por la reapertura del ...

Luis Lliboutry
Louis Lliboutry (born 19 February 1922 in Madrid; died on 21 October 2007 in Grenoble) was a French glaciologist, geophysicist, and mountaineer. While in Chile in the early 1950s, he analysed and explained the formation of snow penitents in the Andes, which marked his first contribution to glaciology. He founded in Grenoble in 1958 the Laboratory of Alpine Glaciology and headed it for 25 years; he also set up at that period a pioneering syllabus in geophysics. His contributions to mechanics of viscous media (such as ice and the Earth's mantle) and to geodynamics are internationally acknowledged. Biography Early years Louis Antonin François Lliboutry was born in Madrid on 19 February 1922, the son of French parents originating from the Perpignan region. Repatriated in 1936 during the Spanish Civil War, he soon revealed his interest for research and exploration, instilled by Jules Verne's novels, while Jean-Henri Fabre's ''Souvenirs entomologiques'' led him to observe and co ...

Climate Of Chile
The climate of Chile comprises a wide range of weather conditions across a large geographic scale, extending across 38 degrees in latitude, making generalizations difficult. According to the Köppen system, Chile within its borders hosts at least seven major climatic subtypes, ranging from low desert in the north, to alpine tundra and glaciers in the east and southeast, tropical rainforest in Easter Island, Oceanic in the south and Mediterranean climate in central Chile. There are four seasons in most of the country: summer (December to February), autumn (March to May), winter (June to August), and spring (September to November). On a synoptic scale, the most important factors that control the climate in Chile are the Pacific Anticyclone, the southern circumpolar low pressure area, the cold Humboldt current, the Chilean Coast Range and the Andes Mountains. Despite Chile's narrowness, some interior regions may experience wide temperature oscillations and cities such as San Pedr ...

Climate Of Argentina
The climate of Argentina varies from region to region, as the vast size of the country and wide variation in altitude make for a wide range of climate types. Summers are the warmest and wettest season in most of Argentina except in most of Patagonia where it is the driest season. Warm in the north, cool in the center and cold in the southern parts experiencing frequent frost and snow. Because southern parts of the country are moderated by the surrounding oceans, the cold is less intense and prolonged than areas at similar latitudes in the northern hemisphere. Spring and autumn are transition seasons that generally feature mild weather. Many regions have different, often contrasting, microclimates. In general, northern parts of the country are characterized by hot, humid, rainy summers and mild winters with periodic droughts. Mesopotamia, in the northeast is characterized by high temperatures and abundant precipitation throughout the year with droughts being uncommon. West of ...

Ecology Of The Andes
Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism. Among other things, ecology is the study of: * The abundance, biomass, and distribution of organisms in the context of the environment * Life processes, antifragility, interactions, and adaptations * The movement of materials and energy through living communities * The successional development of ecosystems * Cooperation, competition, and predation within and between species * Patterns of biodiversity and its effect on ecosystem processes Ecology has practical applications in conservation biology, wetland management, natural resource managemen ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Rock Glacier
Rock glaciers are distinctive geomorphological landforms, consisting either of angular rock debris frozen in interstitial ice, former "true" glaciers overlain by a layer of talus, or something in-between. Rock glaciers are normally found at high latitudes and/or elevations, and may extend outward and downslope from talus cones, glaciers or terminal moraines of glaciers. There are two types of rock glaciers: periglacial glaciers (or talus-derived glaciers), and glacial rock glaciers, such as the Timpanogos Glacier in Utah, which are often found where glaciers once existed. Possible Martian rock glacier features have been identified by the Mars Orbiter spacecraft. A rock glacier, especially if its origin is unclear, can be considered as a discrete debris accumulation. Formation The two known factors that must be present in order to create rock glaciers are low ice velocity and permafrost. Most glacial rock glaciers are created by the recession of debris covered glaciers. Glacial ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Lanín
Lanín is an ice-clad, cone-shaped stratovolcano on the border of Argentina and Chile. It forms part of two national parks: Lanín in Argentina and Villarrica in Chile. It is a symbol of the Argentine province of Neuquén, being part of its flag and its anthem. Although the date of its last eruption is not known, it is estimated to have occurred within the last 10,000 years. Following the 1906 Valparaíso earthquake a local newspaper reported the volcano to have erupted, but a work published in 1917 by Karl Sapper disputed this.Luis E. Lara, José A. Naranjo and Hugo Moreno, 2004Lanín volcano (39.5°S), Southern Andes: geology and morphostructural evolution '' Revista Geológica de Chile'' vol. 31. The ascent is regulated by the management of Argentine National Parks and the Argentine National Gendarmerie and is technically relatively simple but has a much higher level of exposure than the neighbouring volcanoes.

Penitente (snow Formation)
Penitentes, or nieves penitentes (Spanish for " penitent snows"), are snow formations found at high altitudes. They take the form of elongated, thin blades of hardened snow or ice, closely spaced and pointing towards the general direction of the sun. The name comes from the resemblance of a field of penitentes to a crowd of kneeling people doing penance. The formation evokes the tall, pointed habits and hoods worn by brothers of religious orders in the Processions of Penance during Spanish Holy Week. In particular, the brothers' hats are tall, narrow, and white, with a pointed top. These spires of snow and ice grow over all glaciated and snow-covered areas in the Dry Andes above . They range in length from a few centimetres to over . First description Penitentes were first described in scientific literature by Charles Darwin in 1839. On March 22, 1835, he had to squeeze his way through snowfields covered in penitentes near the Piuquenes Pass, on the way from Santiago de Chile t ...
