Pampa Alta Pass (Puesto Viejo)
Pampa Alta Pass (Spanish: ''Paso Pampa Alta''), also known as Puesto Viejo (''Old Post''), is a boundary pass between Argentina and Chile, joining Aysén del General Carlos Ibáñez del Campo Region and Chubut Province. The elevation of the pass is 865 metres (2,838 feet) above sea level. The pathway in this locality is a gravel road and traffic is allowed between 8 am and 8 pm in winter and between 8 am and 10 pm in summer. To leave Chile, it is necessary to obtain a pass from the international police in Coihaique. The nearest police assistance is situated 4 km (2.5 mi) away from the pass and the closest inhabited places are Balmaceda and Coihaique, in Chile. Geography Climate The climate in Pampa Alta Pass is subarctic (''Csc/Dsc'', according to the Köppen climate classification), with drier summers than winters and frequent snow Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accum ...

Argentina
Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world. It shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is a federal state subdivided into twenty-three provinces, and one autonomous city, which is the federal capital and largest city of the nation, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands, and a part of Antarctica. The earliest recorded human prese ...

Subarctic Climate
The subarctic climate (also called subpolar climate, or boreal climate) is a climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50° to 70°N, poleward of the humid continental climates. Subarctic or boreal climates are the source regions for the cold air that affects temperate latitudes to the south in winter. These climates represent Köppen climate classification ''Dfc'', ''Dwc'', ''Dsc'', ''Dfd'', ''Dwd'' and ''Dsd''. Description This type of climate offers some of the most extreme seasonal temperature variations found on the planet: in winter, temperatures can drop to below and in summer, the temperature may exceed . However, the summers are short; no more than three months of the year (but at least one month) must have a 24-hour average temperature of at least to fall into this category of climate, and the coldest month should ave ...

Mountain Passes Of The Andes
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain ...

Snow
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balmaceda, Chile
Balmaceda is a Chilean village ( es, aldea) located south east of Coyhaique in Aysén Region. Balmaceda has around 500 inhabitants, and has Aysén Region's largest airport and meteorological station, Balmaceda Airport. History The first settlers arrived into the zone in early-20th century after being expelled from Argentina since the borders between Chile and Argentina were drawn in 1902. In 1917 Balmaceda was officially founded and was named after the Chilean president José Manuel Balmaceda. Balmaceda was initially one of the largest inland Chilean settlements in what is now the Aysén Region. Transport Balmaceda is linked to Route 40, in Argentina, via a 102 km gravel extension road (not pavement - May/2019 info). Climate The climate of Balmaceda is an unusual combination of the dry-summer Mediterranean characteristic more typical of Central Chile with the subpolar oceanic characteristics more typical of southern Chile.

Chile
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of , with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south. Chile also controls the Pacific islands of Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island in Oceania. It also claims about of Antarctica under the Chilean Antarctic Territory. The country's capital and largest city is Santiago, and its national language is Spanish. Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile. In 1818, after declaring in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coihaique
Coyhaique (), also spelled Coihaique in Patagonia, is the capital city of both the Coyhaique Province and the Aysén Region of Chile. Founded by settlers in 1929, it is a young city. Until the twentieth century, Chile showed little interest in exploiting the remote Aisén region. The Carretera Austral southern highway opened in the 1980s. Geography and climate The commune of Coyhaique spans an area of . It is surrounded by rivers (Simpson and Coyhaique) and by mountains. The mountains may be snow-covered throughout the year, thus Coihaique is sometimes called the city of eternal snow. Under the Köppen climate classification, Coyhaique has an oceanic climate (''Cfb''), though it is considerably less wet than coastal settlements like Puerto Montt or Puerto Aysén since the coastal mountains provide considerable shielding from the westerly winds. Temperatures are moderate during the months of November through April, while from May until October, temperatures are chilly and acco ...

Gravel Road
A gravel road is a type of unpaved road surfaced with gravel that has been brought to the site from a quarry or stream bed. They are common in less-developed nations, and also in the rural areas of developed nations such as Canada and the United States. In New Zealand, and other Commonwealth countries, they may be known as metal roads. They may be referred to as "dirt roads" in common speech, but that term is used more for unimproved roads with no surface material added. If well constructed and maintained, a gravel road is an all-weather road. Characteristics Construction Compared to sealed roads, which require large machinery to work and pour concrete or to lay and smooth a bitumen-based surface, gravel roads are easy and cheap to build. However, compared to dirt roads, all-weather gravel highways are quite expensive to build, as they require front loaders, dump trucks, graders, and roadrollers to provide a base course of compacted earth or other material, sometimes maca ...
