Licancabur
Licancabur () is a stratovolcano on the border between Bolivia and Chile, south of the Sairecabur volcano and west of Juriques. Part of the Andean Central Volcanic Zone, it has a prominent, -high cone. A summit crater containing Licancabur Lake, a crater lake which is among the highest lakes in the world, caps the volcano. Three stages of lava flows emanate from the edifice. Licancabur formed atop of Pleistocene ignimbrites and has been active during the Holocene, after the ice ages. Although no historic eruptions of the volcano are known, lava flows extending into Laguna Verde have been dated to 13,240 ± 100 BP. The volcano has primarily erupted andesite, with small amounts of dacite and basaltic andesite. Its climate is cold, dry and very sunny, with high levels of ultraviolet radiation. Licancabur is not covered by glaciers. Cushion plants and shrubs form the vegetation lower on its slopes. Chinchillas were formerly hunted on the volcano. Licancabur is consider ...

Licancabur Lake
Licancabur Lake is a crater lake in Chile located on the volcano Licancabur (Región de Antofagasta, Province of El Loa). It is close to the city San Pedro de Atacama and also very close to the border of Chile with Bolivia. The lake is among several high altitude volcanic lakes in the region. Licancabur Lake is located inside the summit crater of Licancabur and was discovered by climbers in 1953, when it was long. While the waterbody may have overflowed in the past, presently it is only drained by seepage and evaporation. Lake levels are variable; in 2002 it covered a surface area of . The lake's waters are clear and slightly saline. Temperature readings recorded at the lake bottom in 2006 suggest it is subject to geothermal heating. The local climate is arid, cold and subject to strong insolation, including strong ultraviolet radiation. This has caused the lake to be compared to the environment of Mars. Despite these conditions, bacteria, archaea, crustaceans and even a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sairecabur
Sairecabur () is a volcano located on the frontier between Bolivia and Chile. It is part of the Andean Central Volcanic Zone. Sairecabur proper is high; other mountains in the range are high Curiquinca, high Escalante and high Cerro Colorado, all of which have erupted a number of lava flows. Also in close proximity to Sairecabur lie the volcanic centres Licancabur, Putana and Juriques. Sairecabur proper is accompanied by a wide caldera. Before the formation of this caldera the volcano may have been high and thus one of the highest volcanoes on Earth. After the formation of this caldera lava effusion occurred during the Pleistocene and Holocene; there is no reported historical activity, however. Eruption products on Escalante and Sairecabur include andesite and dacite. The climate is dry, cold and very sunny. An Inca sanctuary has been found on Sairecabur, and sulfur mines exist in the mountain chain. More recently, the Receiver Lab Telescope was installed on the vo ...

Laguna Verde (Bolivia)
__NOTOC__ Laguna Verde (Spanish for "green lake") is a salt lake in an endorheic basin, in the southwestern Altiplano in Bolivia. It is located in the Sur Lípez Province of the Potosí Department. It is close to the Chilean border, at the foot of the volcano Licancabur. Geography The Laguna Verde is a lake at elevation. It covers an area of and has a depth of , and a narrow causeway divides it into two parts. It is at the southwestern extremity of the Eduardo Avaroa Andean Fauna National Reserve and Bolivia itself. It has mineral suspensions of arsenic and other minerals which renders colour to the lake waters. Its color varies from turquoise to dark emerald depending on the disturbance caused to sediments in the lake by winds. In the backdrop of the lake there is the inactive volcano Licancabur of in elevation, which is a nearly perfect cone. The shorelines west and east of the lake have different characteristics, with the western and southern shores eroded into volcanoes ...

Andes
The Andes, Andes Mountains or Andean Mountains (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18°S – 20°S latitude), and has an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Along their length, the Andes are split into several ranges, separated by intermediate 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, El Alto and La Paz. The Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes Mountains are the highest m ...

Volcanic Crater Lake
A volcanic crater lake is a lake in a crater that was formed by explosive activity or a collapse during a volcanic eruption. Formation Lakes in calderas fill large craters formed by the collapse of a volcano during an eruption. Lakes in maars fill medium-sized craters where an eruption deposited debris around a vent. Crater lakes form as the created depression, within the crater rim, is filled by water. The water may come from precipitation, groundwater circulation (often hydrothermal fluids in the case of volcanic craters) or melted ice. Its level rises until an equilibrium is reached between the rates of incoming and outgoing water. Sources of water loss singly or together may include evaporation, subsurface seepage, and, in places, surface leakage or overflow when the lake level reaches the lowest point on its rim. At such a saddle location, the upper portion of the lake is contained only by its adjacent natural volcanic dam; continued leakage through or surface outflow ...

Sacred Mountains
Sacred mountains are central to certain religions, and are usually the subjects of many legends. For many, the most symbolic aspect of a mountain is the peak because it is believed that it is closest to heaven or other religious realms. Many religions have traditions centered on sacred mountains, which either are or were considered holy (such as Mount Olympus in Greek mythology) or are related to famous events (like Mount Sinai in Judaism, Christianity and descendant religions or Mount Kailash in Hinduism). In some cases, the sacred mountain is purely mythical, like the Hara Berezaiti in Zoroastrianism. Mount Kailash is believed to be the abode of the deities Shiva and Parvati, and is considered sacred in four religions: Hinduism, Bon, Buddhism, and Jainism. Volcanoes, such as Mount Etna in Italy, were also considered sacred, Mount Etna being believed to have been the home of Vulcan, the Roman god of fire and the forge.

Chinchilla
Chinchillas are either of two species (''Chinchilla chinchilla'' and ''Chinchilla lanigera'') of crepuscular rodents of the parvorder Caviomorpha. They are slightly larger and more robust than ground squirrels, and are native to the Andes mountains in South America. They live in colonies called "herds" at high elevations up to . Historically, chinchillas lived in an area that included parts of Bolivia, Peru, Argentina, and Chile, but today, colonies in the wild are known only in Chile. Along with their relatives, viscachas, they make up the family Chinchillidae. They are also related to the chinchilla rat. The chinchilla has the densest fur of all mammals that live on land. In the water, the sea otter has a denser coat. The chinchilla is named after the Chincha people of the Andes, who once wore its dense, velvet-like fur. By the end of the 19th century, chinchillas had become quite rare after being hunted for their ultra-soft fur. Most chinchillas currently used by the fur i ...

Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about fiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cushion Plant
A cushion plant is a compact, low-growing, mat-forming plant that is found in alpine, subalpine, arctic, or subarctic environments around the world. The term "cushion" is usually applied to woody plants that grow as spreading mats, are limited in height above the ground (a few inches at most), have relatively large and deep tap roots, and have life histories adapted to slow growth in a nutrient-poor environment with delayed reproductivity and reproductive cycle adaptations. The plant form is an example of parallel or convergent evolution with species from many different plant families on different continents converging on the same evolutionary adaptations to endure the harsh environmental conditions.Went, F. W. (1971). Parallel evolution. ''Taxon'', 20(2/3): 197-226. Description Cushion plants form large, low-growing mats that can grow up to in diameter. The typical form is a compact mass of closely spaced stems with minimal apical dominance that terminate in individual rosett ...

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 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
