Glacieret
A glacieret is a very small glacier, with a surface area less than . The term is sometimes incorrectly used to refer to a large, persistent snow patch of firn or névé. Characteristics Sometimes hardly larger than snowfields and perennial firn patches, glacierets tend to have little ice movement, with accumulation and ablation zones difficult to detect. During the last ice age, glacierets were an intermediate stage between firn patches and fully fledged glaciers, but in the present day, glacierets are usually remnants of larger glaciers that existed. Due to their small size, they are at a higher risk of melting due to climate change than larger glaciers. Examples * Snezhnika in the Pirin range of Bulgaria was the southernmost glacial mass in Europe before the discovery of glaciers on Mount Bazardüzü. * The Banski Suhodol Glacieret, also in the Pirin, is the only other surviving glacial mass in Bulgaria. * There are some glacierets in the range of the Pyrenees. * The Red ...

Snezhnika Glacieret July 2012
Snezhnika ( 'the snow patch') is a glacieret in the Pirin Mountains of Bulgaria, a remnant of the former Vihren Glacier.Grunewald, p. 129. The glacieret lies at an elevation between and in the deep Golemiya Kazan cirque at the steep northern foot of Vihren (), Pirin's highest summit. Due to the relatively easy access and its location along a popular hiking trail, Snezhnika is Bulgaria's most famous glacieret. Snezhnika has an average area of and in 2006 it had a volume of . Snezhnika's size varies in length from 70 to 100 metres (west to east) and in width from 40 to 90 metres (north to south). Its firn is 8–11 m thick at the base and its snow cover, which is mostly fed by avalanche snow, can be as deep as 20 metres in March and April. Snezhnika's latitude of 41°46′09″ N makes it the southernmost glacial mass in Europe; the nearby Banski Suhodol Glacier below Koncheto, although larger, is slightly to the north. Snezhnika lies in an east-facing hollow adjacent to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Southernmost Glacial Mass In Europe
The southernmost persistent glacial masses in Europe are mainly small glaciers, glacierets, and perennial firn fields and patches, located in the highest mountains of the three big southern European peninsulas - the Balkans, Balkan, the Italian Peninsula, Apennine, and the Iberian Peninsula, Iberian, the southernmost ranges of the Alps and the glaciers on the european northwestern slopes of the Greater Caucasus mountains in Russia. There are summer lasting snow patches in Sierra Nevada (Spain), Sierra Nevada (Corral de la Veleta (Sierra Nevada), Veleta glacier at 37°03′24″ disappeared completely for a first time in 1913), in Mount Olympus (40°05′08″) (Kazania cirque), in Korab (mountain), Mount Korab (41°47′28″), in Rila Mountain (the cirque of the Seven Rila Lakes, Musala and Malyovitsa (42°10′25″) ridges), in Picos de Europa (43°11′51″) in the Cantabrian Mountains, in Maglić (mountain), Mount Maglić (43°16′52″) and others.

Banski Suhodol Glacier
The Banski Suhodol Glacier (, ''Lednika v Banski Suhodol'') is a glacieret in the Pirin Mountains of Bulgaria. It lies below the Kutelo peak (2908 m.) in the upper Banski Suhodol Valley (). Geography The glacier is on the northern slope of the Kutelo summit and is shaded from the east by the Koncheto ridge. After the nearby Snezhnika glacier (latitude of 41°46′09″ N) Banski Suhodol glacier is the southernmost in Europe, followed by three small glaciers below the Maja Jezerce summit in northern Albania, the Calderone glacier in the Gran Sasso mountain in Italy, and Debeli Namet glacier in Montenegro. Together with the nearby Snezhnika glacieret below Vihren Vihren ( ) is the highest peak of Bulgaria's Pirin Mountains. Reaching , it is Bulgaria's second and the Balkans' third highest, after Musala and Mount Olympus. Although Vihren is deprived of lakes and streams due to the karst topography, a numb ..., it is one of two surviving glacial masses in Bulgaria.Emil Gac ...

Red Eagle Glacier
Red Eagle Glacier is a glacier remnant (glacieret) in Glacier National Park (U.S.), Glacier National Park in the U.S. state of Montana. The glacieret is a hanging glacier located on the north slope of Clyde Peak, and to the southeast of Mount Logan (Montana), Mount Logan and Logan Glacier (Montana), Logan Glacier. Between 1966 and 2005, Red Eagle Glacier lost 53 percent of its surface area and now covers less than which is below the threshold to qualify as an active glacier. Comparing images of the glacier taken in 1914 with those from 2009, indicates that the glacier has experienced extensive retreat.

Shepard Glacier
Shepard Glacier is a glacier remnant (glacieret) In Glacier National Park in the U.S. state of Montana. The glacieret is immediately southeast of Cathedral Peak. Shepard Glacier was one of a number of glaciers that have been documented by the United States Geological Service (USGS) to have retreated significantly in Glacier National Park. Shepard Glacier was measured in 2009 to have decreased to less than , considered to be a minimal size to qualify as being considered an active glacier. Between 1966 and 2005, Shepard Glacier lost 56 percent of its surface area. Comparing the 2005 image at right to the one below taken in 1913, it is apparent that Shepard glacier has retreated significantly between these dates.

Calderone Glacier
The Calderone glacier () is a glacier located in the Apennine Mountains in Abruzzo, Italy. Found in the Gran Sasso d'Italia mountain group, it lies just beneath the Corno Grande, the highest peak in the Apennines. With the disappearance of the Corral de la Veleta glacier in the Sierra Nevada in 1913, "Il Calderone" became one of Europe's southernmost known glaciers (42°28′N, 13°33′E), being slightly to the north only compared to Snezhnika (latitude of 41°46′09″ N) and Banski Suhodol Glaciers in Pirin Mountain in Bulgaria. If present deglaciation trends continue, the Calderone may soon disappear as well. The discovery of a number of small glaciers in the Accursed Mountains in 2009 seemed to threaten Calderone's positions. Historical surface of the glacier In 1794, the Calderone had an estimated volume of over 4 million cubic metres; by 1916, the glacier’s volume had decreased to 3.3 million cubic metres, and by 1990, it had decreased to 360,931 cubic metres.

Névé
Névé is a young, granular type of snow which has been partially melted, refrozen and compacted, yet precedes the form of ice. This type of snow can contribute to glacier formation through the process of ''nivation''. Névé that survives a full season of ablation turns into firn, which is both older and slightly denser. Firn eventually becomes glacial ice – the long-lived, compacted ice that glaciers are composed of. Glacier formation can take years to hundreds of years, depending on freeze-thaw factors and snow-compaction rates. Névé is annually observed in skiing slopes, and is generally disliked as an icy falling zone. Névé has a minimum density of 500 kg/m3, which is Density#Water, roughly half of the density of liquid water at 1 Atmosphere (unit), atm. Névé can also refer to the Alpine climate, alpine region in which snowfall accumulates, becomes névé, and feeds a glacier. See also * Suncup (snow), Suncup Notes External links * Névés, ...

Little Ice Age
The Little Ice Age (LIA) was a period of regional cooling, particularly pronounced in the North Atlantic region. It was not a true ice age of global extent. The term was introduced into scientific literature by François E. Matthes in 1939. Matthes described glaciers in the Sierra Nevada (U.S.), Sierra Nevada of California that he believed could not have survived the hypsithermal; his usage of "Little Ice Age" has been superseded by "Neoglaciation". The period has been conventionally defined as extending from the 16th to the 19th centuries, (noted in Grove 2004: 4). but some experts prefer an alternative time-span from about 1300 to about 1850. The NASA Earth Observatory notes three particularly cold intervals. One began about 1650, another about 1770, and the last in 1850, all of which were separated by intervals of slight warming. The Intergovernmental Panel on Climate Change IPCC Third Assessment Report, Third Assessment Report considered that the timing and the areas affecte ...

Sierra Nevada
The Sierra Nevada ( ) is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, an almost continuous chain of mountain ranges that forms the western "backbone" of the Americas. The Sierra runs north-south, and its width ranges from to across east–west. Notable features include the General Sherman Tree, the largest tree in the world by volume; Lake Tahoe, the largest alpine lake in North America; Mount Whitney at , the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers from one-hundred-million-year-old granite, containing high waterfalls. The Sierra is home to three national parks, twenty-six wilderness areas, ten national forests, and two national monuments. These areas include Yosemite, Sequoia, and Ki ...

Corral De La Veleta
Veleta (from the Arab word "Balata", meaning cliff) or Pico del Veleta is the third highest peak of the Iberian Peninsula and the second highest of the Sierra Nevada. Its height is given variously as , and . The mountain can be seen from the city of Granada. Veleta's northern slopes are home to the Sierra Nevada Ski Station. The access road that takes one to approximately 10 metres below the summit is the highest paved road in Europe across the mountains from Granada to the western Alpujarras. This road was built before the creation of the Sierra Nevada National Park in 1999. It has since been closed to general traffic beyond Hoya de la Mora, just above the ski station. However, the road is still used by ski station employees, national park rangers, observatory staff, cyclists and walkers, and by a microbus service which takes hikers up to Posiciones del Veleta, a viewpoint 3,100 metres above sea level. In summer it is a relatively easy walk up to the summit from there. The C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
