Cerro Del Bolsón
Cerro del Bolsón is a mountain in the Aconquija Range of Argentina, on the border between Catamarca and Tucumán provinces. It is the highest point of a significant eastern spur of the main range of the Andes, east of the Puna de Atacama region. It lies about 200 kilometres east of Ojos del Salado, the highest point in the Puna de Atacama. While not of great height compared to the 6000 metre-plus peaks of the main chain of the Andes to the west, Bolsón is notable for its high topographic prominence (it ranks 69th in the world), resulting from its separation from the main chain by a relatively low saddle. The name comes from the Spanish word "bolsa" or bag. The -on suffix denotes large. However in most of Latin America the term is used geographically to denote a hollow or enclosed valley,e.g. El Bolsón, Río Negro El Bolsón is a town in the southwest of Río Negro Province, Argentina, at the foot of the Piltriquitron Mountain. Due to a series of valleys through the moun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Peaks By Prominence
This is a list of mountain peaks ordered by their topographic prominence. Terminology The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. The lowest point on that route is the col. For full definitions and explanations of ''topographic prominence'', ''key col'', and ''parent'', see topographic prominence. In particular, the different definitions of the parent of a peak are addressed at length in that article. ''Height'' on the other hand simply means elevation of the summit above sea level. Regarding parents, the ''prominence parent'' of peak A can be found by dividing the island or region in question into territories, by tracing the runoff from the key col (mountain pass) of every peak that is more prominent than peak A. The parent is the peak whose territory peak A resides in. The ''encirclement parent'' is found by tracing the contour below peak A's key col and picking the hig ...

Mountain Pass
A mountain pass is a navigable route through a mountain range or over a ridge. Since mountain ranges can present 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 minimum high point between two valleys and the lowest point along a ridge. On a topographic map, passes can be identified 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 pass. Passes are o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of Tucumán Province
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...

Mountains Of Argentina
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 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 and climate, mountains t ...

Bolson
A bolson is a desert valley or depression, usually draining into a playa or salt pan, and entirely surrounded by recently uplifted hills or mountains. Bolsons are sites of active deposition of sediments (aggradation).* They are a type of endorheic basin characteristic of basin and range topography. The term was an Americanism originating in the 1830s and 1840s during the explorations of the far west of North America, particularly of what became the Southwestern United States and northern Mexico. It was derived from the Spanish ''bolsón'' (large purse). bolson from www.britannica.com accessed July 29, 2018 Examples of this type of formation would be the Hueco Bolson in the western [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
El Bolsón, Río Negro
El Bolsón is a town in the southwest of Río Negro Province, Argentina, at the foot of the Piltriquitron Mountain. Due to a series of valleys through the mountains of Chile to the Pacific Ocean, El Bolsón has an unusually mild climate for its southern location. El Bolsón area's first non-indigenous inhabitants were Chilean farmers Lucas Cárdenas and Elcira Estrada, a couple who came in 1885 from San Pablo, near Osorno, and established themselves in the then known as "Valle Nuevo" (New Valley); in 2018, El Bolsón inaugurated the new Public Clock Square after the couple's names. In the 1970s, hippies from Buenos Aires migrated to El Bolsón; some of them practised horticulture and made handcrafts. El Bolsón has a tourism economy based on an outdoor artisan market, fly fishing, trekking, rafting, climbing, and other outdoor activities in the surrounding lakes and mountains. The nature tourism offers are complemented with the production of cheeses, smoked trout, special brew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin America
Latin America is the cultural region of the Americas where Romance languages are predominantly spoken, primarily Spanish language, Spanish and Portuguese language, Portuguese. Latin America is defined according to cultural identity, not geography, and as such it includes countries in both North and South America. Most countries south of the United States tend to be included: Mexico and the countries of Central America, South America and the Caribbean. Commonly, it refers to Hispanic America plus Brazil. Related terms are the narrower Hispanic America, which exclusively refers to Spanish-speaking nations, and the broader Ibero-America, which includes all Iberic countries in the Americas and occasionally European countries like Spain, Portugal and Andorra. Despite being in the same geographical region, English- and Dutch language, Dutch-speaking countries and territories are excluded (Suriname, Guyana, the Falkland Islands, Jamaica, Trinidad and Tobago, Belize, etc.), and French- ...

Topographic Prominence
In topography, prominence or relative height (also referred to as autonomous height, and shoulder drop in US English, and drop in British English) measures the height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. The key col ("saddle") around the peak is a unique point on this contour line and the ''parent peak'' (if any) is some higher mountain, selected according to various criteria. Definitions The prominence of a peak is the least drop in height necessary in order to get from the summit to any higher terrain. This can be calculated for a given peak in the following manner: for every path connecting the peak to higher terrain, find the lowest point on the path; the ''key col'' (or ''highest saddle (landform), saddle'', or ''linking col'', or ''link'') is defined as the highest of these points, along all connecting paths; the prominence is the differ ...

Ultra Prominent Peak
An ultra-prominent peak, or ultra for short, is a mountain summit with a topographic prominence of or more; it is also called a P1500. The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. There are approximately 1,500 such peaks on Earth. Some well-known peaks, such as the Matterhorn and Eiger, are not ultras because they are connected to higher mountains by high cols and thus do not achieve enough topographic prominence. The term "ultra" originated with earth scientist Steve Fry, from his studies of the prominence of peaks in Washington (state), Washington in the 1980s. His original term was "ultra major mountain", referring to peaks with at least of prominence. Distribution Currently, over 1,500 ultras have been identified above sea level: 654 in Asia, 357 in North America, 209 in South America, 119 in Europe (including 12 in the Caucasus), 84 in Africa, 54 in Oceania, and 39 in ...

Ojos Del Salado
Nevado Ojos del Salado is a Dormant volcano, dormant complex volcano in the Andes on the Argentina–Chile border. It is the highest volcano on Earth and the highest peak in Chile. The upper reaches of Ojos del Salado consist of several overlapping lava domes, lava flows and volcanic craters, with sparse ice cover. The complex extends over an area of and its highest summit reaches an altitude of above sea level. Numerous other volcanoes rise around Ojos del Salado. Being close to the Arid Diagonal of South America, the mountain has extremely dry conditions, which prevent the formation of substantial glaciers and a permanent snow cover. Despite the arid climate, there is a permanent Volcanic crater lake, crater lake about in diameter at an elevation of - within the summit crater and east of the main summit. This is the Lake#Notable lakes on Earth, highest lake of any kind in the world. Owing to its altitude and the desiccated climate, the mountain lacks vegetation. Ojos del Sa ...

Atacama Desert
The Atacama Desert () is a desert plateau located on the Pacific Ocean, Pacific coast of South America, in the north of Chile. Stretching over a strip of land west of the Andes Mountains, it covers an area of , which increases to if the barren lower slopes of the Andes are included. The Atacama Desert is the driest nonpolar desert in the world, and the second driest overall, behind some specific spots within the McMurdo Dry Valleys. It is the only Desert climate, true desert to receive less precipitation than polar deserts, and the largest fog desert in the world. The area has been used as an experimentation site for Mars expedition simulations due to its similarities to the Martian environment. The constant Inversion (meteorology), temperature inversion caused by the cool north-flowing Humboldt Current, Humboldt ocean current and the strong South Pacific High, Pacific anticyclone contribute to the extreme aridity of the desert. The most arid region of the Atacama Desert is s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
