Queulat National Park
Queulat National Park is a national park of Chile located in the Aysén del General Carlos Ibáñez del Campo Region. The park is bordered by the Cisnes River on the south side and is neighbor to Lago Rosselot National Reserve. It contains of glacier-capped mountains and virgin evergreen forests. History In 1766, the Jesuit Father José García Alsue explored the area searching for the City of the Caesars. Park geography Local relief is dominated by the Patagonian Andes, with some elevations greater than above sea level. A portion of the Puyuhuapi Volcanic Group form part of the park, specifically the area south of the Lake Risopatrón. The park comprises two small ice fields, with glaciers of up to long. The largest glaciated area is Queulat ice cap, which encompasses about and contains the park's centerpiece, the Queulat Hanging Glacier. This ice cap is centered at , and is at an elevation of . The other ice cap covers an area of approximately and is centered at an unname ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Understory
In forestry and ecology, understory (American English), or understorey (Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy so understory vegetation is generally shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines and undergrowth. Small trees such as holly and dogwood are understory specialists. In temperate deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the potential emergent trees into competitive growth as they grow upwards to fill the gap. These trees tend to have straight trunks ...

Kodkod
The kodkod (''Leopardus guigna'') (), also called guiña, is the smallest felid species native to the Americas. It lives primarily in central and southern Chile, as well as marginally in adjoining areas of Argentina. Since 2002, it has been listed as Vulnerable on the IUCN Red List as the total population may be less than 10,000 mature individuals; it is threatened by persecution, and loss of habitat and prey base. Characteristics The kodkod's fur color ranges from brownish-yellow to grey-brown. It has dark spots, a pale underside and a ringed tail. The ears are black with a white spot, while the dark spots on the shoulders and neck almost merge to form a series of dotted streaks. Melanistic kodkods with spotted black coats are quite common. It has a small head, large feet, and a thick tail. Adult kodkods are in head to body length with a short tail and a shoulder height of about . Weight ranges between . Melanistic phenotype The melanistic phenotype is caused by the deletion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pudú
The pudus (Mapudungun ''püdü'' or ''püdu'', es, pudú, ) are two species of South American deer from the genus ''Pudu'', and are the world's smallest deer. The chevrotains (mouse-deer; Tragulidae) are smaller, but they are not true deer. The name is a loanword from Mapudungun, the language of the indigenous Mapuche people of central Chile and south-western Argentina. The two species of pudus are the northern pudu (''Pudu mephistophiles'') from Venezuela, Colombia, Ecuador, and Peru, and the southern pudu (''Pudu puda''; sometimes incorrectly modified to ''Pudu pudu'') from southern Chile and south-western Argentina. Pudus range in size from tall, and up to long. The southern pudu is classified as near threatened, while the northern pudu is classified as Data Deficient in the IUCN Red List. Taxonomy The genus ''Pudu'' was first erected by English naturalist John Edward Gray in 1850. ''Pudua'' was a Latinized version of the name proposed by Alfred Henry Garrod in 1877, but wa ...

Mountain Pass
A mountain pass is a navigable route through a mountain range or over a ridge. Since many of the world's mountain ranges have presented formidable barriers to travel, passes have played a key role in trade, war, and both Human migration, human and animal migration throughout history. At lower elevations it may be called a hill pass. A mountain pass is typically formed between two volcanic peaks or created by erosion from water or wind. Overview Mountain passes make use of a gap (landform), gap, saddle (landform), saddle, col or notch (landform), notch. A topographic saddle is analogous to the mathematical concept of a saddle surface, with a saddle point marking the highest point between two valleys and the lowest point along a ridge. On a topographic map, passes are characterized by contour lines with an hourglass shape, which indicates a low spot between two higher points. In the high mountains, a difference of between the summit and the mountain is defined as a mountain pas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carretera Austral
The Carretera Austral (CH-7, ''in English: Southern Way'') is the name given to Chile's Route 7. The highway runs south for about from Puerto Montt to Villa O'Higgins, passing through rural Patagonia. Carretera Austral provides road access to Chile's Aysén Region and southern parts of Los Lagos Region. These areas are sparsely populated and despite its length, Carretera Austral provides access to only about 100,000 people. The largest city along the entire road is Coyhaique with a population of 44,850 in 2002. History Construction of the highway was commenced in 1976 under the dictatorship of Augusto Pinochet in order to connect a number of remote communities. Before that, in the 1950s and 1970s, there had been unsuccessful attempts to build access roads in the region. It is among the most ambitious infrastructure projects developed in Chile during the 20th century. As it was constructed during the military dictatorship, the Carretera Austral bears the unofficial name of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altitudinal Zonation
Altitudinal zonation (or elevational zonation) in mountainous regions describes the natural layering of ecosystems that occurs at distinct elevations due to varying environmental conditions. Temperature, humidity, soil composition, and solar radiation are important factors in determining altitudinal zones, which consequently support different vegetation and animal species. Altitudinal zonation was first hypothesized by geographer Alexander von Humboldt who noticed that temperature drops with increasing elevation. Zonation also occurs in intertidal and marine environments, as well as on shorelines and in wetlands. Scientist C. Hart Merriam observed that changes in vegetation and animals in altitudinal zones map onto changes expected with increased latitude in his concept of life zones. Today, altitudinal zonation represents a core concept in mountain research. Factors A variety of environmental factors determines the boundaries of altitudinal zones found on mountains, ranging f ...

Hairpin Turn
A hairpin turn (also hairpin bend or hairpin corner) is a bend in a road with a very acute inner angle, making it necessary for an oncoming vehicle to turn about 180° to continue on the road. It is named for its resemblance to a bent metal hairpin. Such turns in ramps and trails may be called switchbacks in American English, by analogy with switchback railways. Description Hairpin turns are often built when a route climbs up or down a steep slope, so that it can travel mostly across the slope with only moderate steepness, and are often arrayed in a zigzag pattern. Highways with repeating hairpin turns allow easier, safer ascents and descents of mountainous terrain than a direct, steep climb and descent, at the price of greater distances of travel and usually lower speed limits, due to the sharpness of the turn. Highways of this style are also generally less costly to build and maintain than highways with tunnels. On occasion, the road may loop completely, using a tunnel or ...

Nothofagus Pumilio
''Nothofagus pumilio'', the lenga beech (from the Mapuche language), is a deciduous tree or shrub in the Nothofagaceae family that is native to the southern Andes range, in the temperate forests of Chile and Argentina to Tierra del Fuego, from 35° to 56° South latitude. This tree is in the same genus as the coihue. It regenerates easily after fires. The wood is of good quality, moderate durability, and is easy to work with. It is used in furniture, shingles and construction and sometimes as a substitute for American black cherry in the manufacturing of cabinets. Description In southern Patagonia it grows to a height of up to 30 m (100 ft), and attains a trunk diameter of 1.5 m (5 ft). In more northern regions it grows only at heights above 1000 meters (3300 ft) in the form of a shrub. The leaves are dark green, elliptic toothed and 2–4 cm long, with irregularly lobed margins, and turn to yellow and reddish tones in autumn. The fruit is a small nu ...

Nothofagus Betuloides
''Nothofagus betuloides'', Magellan's beech or ''guindo'', is a tree native to southern Patagonia. In 1769, Sir Joseph Banks collected a specimen of the tree in Tierra del Fuego during Captain Cook's first voyage. Its occurrence on Hornos Island earns it the distinction of being the southernmost tree on Earth. Distribution ''Nothofagus betuloides'' grows from southern Chile and southern Argentina (40°S) to Tierra del Fuego (56°S). It is found from sea level to above mean sea level. One specimen growing near the southeastern corner of Hornos Island (Cape Horn) was identified in 2019 as the southernmost tree in the world. Description It is an evergreen tree up to tall, with a columnar appearance. In its natural environment, it tolerates cold winters and absence of heat in summer. Specimens from the southern forests resist temperatures down to . Cultivation It succeeds in Scotland. Trees planted in the Faroe Islands, which were imported directly from its southernmost distrib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nalca
''Gunnera tinctoria'', known as giant rhubarb or Chilean rhubarb, is a flowering plant species native to southern Chile and neighbouring zones in Argentina. It is unrelated to rhubarb, as the two plants belong into different orders, but looks similar from a distance and has similar culinary uses. It is a large-leaved perennial plant that grows to more than two metres tall. It has been introduced to many parts of the world as an ornamental plant and in some countries (for instance New Zealand, Great Britain and Ireland) it has spread from gardens and is becoming a weed problem. It is known under the synonyms: ''Gunnera chilensis'' Lam. and ''Gunnera scabra'' Ruiz & Pav. Taxonomy It was first described in 1782 by Juan Ignacio Molina as ''Panke tinctoria'', and was transferred to the genus, ''Gunnera'', in 1805 by Charles-François Brisseau de Mirbel. Description ''Gunnera tinctoria'' is a giant, clump-forming herbaceous perennial. The leaves can grow up to 2.5m across, cor ...
