Sarmiento Channel
Sarmiento Channel is a principal Patagonia channel, which extends in a north–south direction. It begins with the Guia Narrows (''Angostura Guía'') and is located in Magallanes y Antártica Chilena Region. The kawésqar people sailed its waters from around 6,000 years ago until end of 20th century, as they inhabited its coasts. The channel is named after Pedro Sarmiento de Gamboa, who was a Spanish explorer who navigated the region's waterways between 1579 and 1580. This elongated water passage begins immediately south of the Guía Narrows at and terminates at the southern tip of Victoria Pass at , where it joins to Smyth Channel. During the first 65 nautical miles, it runs in a general south-southeasterly direction, and is flanked by Chile mainland on the east and Esperanza, Vancouver and Piazzi islands on the west. Then it turns abruptly eastward for about 4 nmi, where the channel's name changes to Farquhar Pass. It then resumes its general SSE course, merging with Colling ...

Patagonia
Patagonia () refers to a geographical region that encompasses the southern end of South America, governed by Argentina and Chile. The region comprises the southern section of the Andes Mountains with lakes, fjords, temperate rainforests, and glaciers in the west and deserts, tablelands and steppes to the east. Patagonia is bounded by the Pacific Ocean on the west, the Atlantic Ocean to the east, and many bodies of water that connect them, such as the Strait of Magellan, the Beagle Channel, and the Drake Passage to the south. The Colorado and Barrancas rivers, which run from the Andes to the Atlantic, are commonly considered the northern limit of Argentine Patagonia. The archipelago of Tierra del Fuego is sometimes included as part of Patagonia. Most geographers and historians locate the northern limit of Chilean Patagonia at Huincul Fault, in Araucanía Region.Manuel Enrique Schilling; Richard WalterCarlson; AndrésTassara; Rommulo Vieira Conceição; Gustavo Walter B ...

Fjords And Channels Of Chile
The southern coast of Chile presents a large number of fjords and fjord-like channels from the latitudes of Cape Horn (55° S) to Reloncaví Estuary (42° S). Some fjords and channels are important navigable channels providing access to ports like Punta Arenas, Puerto Chacabuco and Puerto Natales. History Indigenous peoples The earliest known inhabitants of the fjords and channels were, from north to south, the Chono, Alacalufe and Yaghan, all of whom shared a life style as canoe-faring hunter-gatherers. They also shared physical traits such as being of low stature, long-headed (''Dolichocephalic''), and having a "low face".Trivero Rivera 2005, p. 42. Despite similarities their languages were completely different.Trivero Rivera 2005, p. 33. The Chono moved around in the area from Chiloé Archipelago to 50° S and the Alacalufe from 46° S to the Strait of Magellan. Thus both groups overlapped in Gulf of Penas, Guayaneco Archipelago and other islands. Yaghans inhabited a reduced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by Highland (geography), highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same Structural geology, geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example Thrust fault, thrust sheets, Fault-block mountain, uplifted blocks, Fold (geology), fold mountains, and vol ...

Cordillera Sarmiento
The Cordillera Sarmiento is a mountain range located in the Chilean Patagonia to the west of Puerto Natales named after Pedro Sarmiento de Gamboa, who was a Spanish explorer who navigated the region's waterways between 1579 and 1580. It extends in north–south direction on the western shore of the Fjord of the Mountains and parallel to the Cordillera Riesco. The highest mountain in this range is ''La Dama Blanca'' (The White Lady), with an elevation of 1,941 m (6,368 feet), which is located at . It is a subrange of the Andes and has a number of small glaciers. Geography A natural continuation of the Southern Patagonian Ice Field, Cordillera de Sarmiento is a mountainous peninsula about long and wide. The range centers about the 52° South line of latitude, west of Puerto Natales. The main summits of the range are La Dama Blanca (), followed to the south by Cerro Trono () and Alas de Ángel (). Three more summits rise over , and many of the peaks are ice-covered towers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Channel (geography)
In physical geography, a channel is a type of landform consisting of the outline of a path of relatively shallow and narrow body of water or of other fluids (e.g., lava), most commonly the confine of a river, river delta or strait. The word is cognate to canal, and sometimes takes this form, e.g. the Hood Canal. Formation Channel initiation refers to the site on a mountain slope where water begins to flow between identifiable banks.Bierman, R. B, David R. Montgomery (2014). Key Concepts in Geomorphology. W. H. Freeman and Company Publishers. United States. This site is referred to as the channel head and it marks an important boundary between hillslope processes and fluvial processes. The channel head is the most upslope part of a channel network and is defined by flowing water between defined identifiable banks. A channel head forms as overland flow and/or subsurface flow accumulate to a point where shear stress can overcome erosion resistance of the ground surface. Channel ...

Nautical Mile
A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. Historically, it was defined as the meridian arc length corresponding to one minute ( of a degree) of latitude. Today the international nautical mile is defined as exactly . The derived unit of speed is the knot, one nautical mile per hour. Unit symbol There is no single internationally agreed symbol, with several symbols in use. * M is used as the abbreviation for the nautical mile by the International Hydrographic Organization. * NM is used by the International Civil Aviation Organization. * nmi is used by the Institute of Electrical and Electronics Engineers and the United States Government Publishing Office. * nm is a non-standard abbreviation used in many maritime applications and texts, including U.S. Government Coast Pilots and Sailing Directions. It conflicts with the SI symbol for nanometre. History The word mile is from the Latin word for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smyth Channel
Smyth Channel () is a principal Patagonia channel. Its south arm is the southward continuation of the Sarmiento Channel and is located in Magallanes y Antártica Chilena Region. The Kawésqar people lived along its coast for thousands of years. Its north entrance is in the Nelson Strait at , between Charlton Cape and the western extreme of the Lobos Islands; and its southern terminus is at , between Phillip Cape at the southern extreme of Manuel Rodriguez Island and Merino Peninsula on the mainland, where it opens into the Strait of Magellan. The channel has a length of approximately 96 nmi and is divided into two arms: the northwest arm, which is scarcely used as navigation route and is 50 nmi long, and the south arm (46 nmi long), which is a major waterway for commercial sailing and that stretches from its connection with the Sarmiento Channel at southern tip of the Victoria Pass until the point already named, where it joins to the Strait of Magellan. The channel is flanked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
