Giétro Glacier
The Giétro Glacier or Giétroz Glacier (french: Glacier du Giétro) is a 4 km long valley glacier located in south-western Switzerland. The 1818 Giétro Glacier catastrophe, which led to lake outburst flood, is one of the most famous and most disastrous historical cases in the Swiss Alps. Description The Giétro Glacier lies on the northern side of the Pennine Alps in the Swiss canton of Valais. It is located in the upper Bagnes Valley, south of Martigny and Verbier. The length of the glacier is 4.45 km (2017) and its area is 5.3 km2 (2017). The glacier is fed by the snows of Mont Blanc de Cheilon (3,870 m) and La Ruinette (3,875 m). On the upper part, the glacier is relatively flat. It descends to the north on the side of Mont Rouge du Giétro and then curves to the west between Le Pleureur and Mont Rouge. On the lower part, the glacier reaches a steepness of 40% forming a large number of crevasses. The terminus is located at about 2,750 metres. Part of the g ...

Lake Mauvoisin
__NOTOC__ Lac de Mauvoisin is a reservoir in the canton of Valais, Switzerland. The reservoir is formed by the Mauvoisin Dam, which is high. The dam is the List of world's tallest dams, 11th highest in the world, and the 6th highest arch dam. It was built in 1951–1957, and raised by in 1991. The reservoir lies in the upper Val de Bagnes, between the massif of the Grand Combin, one of the highest mountains of the Alps, and La Ruinette. The highest peak visible from the lake is the Combin de la Tsessette ().

Ignaz Venetz
Ignaz (Ignace) Venetz (1788 — 1859) was a Swiss engineer, naturalist, and glaciologist; as one of the first scientists to recognize glaciers as a major force in shaping the earth, he played a leading role in the foundation of glaciology. Biography Venetz was of a family long settled in the Valais, where he worked as cantonal engineer first for Valais and then for Vaud. As cantonal engineer he directed the ultimately unsuccessful attempt to drain the ice-dammed lake that had formed following the volcanic winter of 1816 high in the Val de Bagnes; the ice dam failed catastrophically on June 16, 1818. He worked primarily in the Valais canton area of the western Alps. In 1821 he completed the first draft of his work "Mémoire sur les Variations de la température dans les Alpes de la Suisse", suggesting that much of Europe had at one point in the past been covered by glaciers. The book was published in 1833 after additional research in the Swiss Alps, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serac
A serac (from Swiss French ''sérac'') is a block or column of glacial ice, often formed by intersecting crevasses on a glacier. Commonly house-sized or larger, they are dangerous to mountaineers, since they may topple with little warning. Even when stabilized by persistent cold weather, they can be an impediment to glacier travel. Seracs are found within an icefall, often in large numbers, or on ice faces on the lower edge of a hanging glacier. Notable examples of the overhanging glacier edge type are well-known obstacles on some of the world's highest mountains, including K2 at "The Bottleneck" and Kanchenjunga on the border of India and Nepal. Significant seracs in the Alps are found on the northeast face of Piz Roseg, the north face of the Dent d'Hérens, and the north face of Lyskamm. Incidents * On a 1969–1970 Japanese expedition to Mount Everest, Kyak Tsering was killed by a falling serac. * In 1990, an earthquake caused a block of serac to fall off Lenin Peak, trigge ...

Year Without A Summer
The year 1816 is known as the Year Without a Summer because of severe climate abnormalities that caused average global temperatures to decrease by . Summer temperatures in Europe were the extreme weather, coldest on record between the years of 1766–2000. This resulted in major food shortages across the Northern Hemisphere. Evidence suggests that the anomaly was predominantly a volcanic winter event caused by the massive 1815 eruption of Mount Tambora in April in the Dutch East Indies (known today as Indonesia). This eruption was the largest in at least 1,300 years (after the hypothesized eruption causing the volcanic winter of 536), and was perhaps exacerbated by the 1814 eruption of Mayon in the Philippines. Description The Year Without a Summer was an agricultural disaster. Historian John D. Post has called this "the last great subsistence crisis in the Western world".Evans, RoberBlast from the Past ''Smithsonian Magazine''. July 2002, p. 2 The climatic aberrations of 1816 h ...

Glacial Lake Outburst Flood
A glacial lake outburst flood (GLOF) is a type of outburst flood caused by the failure of a dam containing a glacial lake. An event similar to a GLOF, where a body of water contained by a glacier melts or overflows the glacier, is called a jökulhlaup. The dam can consist of glacier ice or a terminal moraine. Failure can happen due to erosion, a buildup of water pressure, an avalanche of rock or heavy snow, an earthquake or cryoseism, volcanic eruptions under the ice, or massive displacement of water in a glacial lake when a large portion of an adjacent glacier collapses into it. Increasing glacial melting because of climate change, alongside other environmental effects of climate change (i.e permafrost melting) mean that regions with glaciers are likely to see increased flooding risks from GLOFs. This is especially true in the Himalayas where geologies are more active. Definition A glacial lake outburst flood is a type of outburst flood occurring when water dammed by a glac ...

Glacier Giétro - Escher Von Der Linth, 1818
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 over many years, often centuries. It acquires distinguishing features, such as crevasses and 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. Between latitudes 35°N and 35°S, glaciers occur only in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
