Baker Channel
Baker Channel, also known as Calen Inlet, is a channel of Chile located in the Tortel, Aysén del General Carlos Ibáñez del Campo Region. The Baker River discharges into Martinez Inlet, the northern part of this large estuary. It penetrates the mainland about and opens into Tarn Bay at the south-east corner of the Gulf of Penas. Merino Jarpa Island lies wholly within this great estuary, while at its mouth lies a group of smaller islands, called Baker Islands, which separate it from Messier Channel. Baker Channel also receives the waters of the O'Higgins/San Martín Lake through the Pascua River. The lake's far-reaching fjord-like arms extend approximately from lat. 49° 11' to 48° 22' S. Its north-west arm is that which drains into the mentioned river. The calving front of Jorge Montt Glacier, which is the northern glacier of the Southern Patagonian Ice Field, reaches the Baker Channel. A number of icebergs can be seen in this area. The channel marks the northern bor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Channel (geography)
In physical geography and hydrology, a channel is a landform on which a relatively narrow body of water is situated, such as a river, river delta or strait. While ''channel'' typically refers to a natural formation, the cognate term ''canal'' denotes a similar artificial structure. Channels are important for the functionality of ports and other bodies of water used for Navigability, navigability for shipping. Naturally, channels will change their depth and capacity due to erosion and Deposition (geology), deposition processes. Humans maintain navigable channels by dredging and other engineering processes. By extension, the term also applies to fluids other than water, e.g., lava channels. The term is also traditionally used to describe the Venusian channels, waterless surface features on Venus. 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 Geom ...

Northern Patagonian Ice Field
The Northern Patagonian Ice Field, located in southern Chile, is the smaller of two remnant parts in which the Patagonian Ice Sheet in the Andes Mountains of southern South America can be divided. It is completely contained within the boundaries of Laguna San Rafael National Park. Description The Northern Patagonian Ice Field is a vestige of the Patagonian Ice Sheet, an extensive ice sheet that covered all of Chilean Patagonia and the westernmost parts of Argentine Patagonia during the Quaternary glaciations. Today, with its glaciers largely in retreat and only an area of , it is still the second largest continuous mass of ice outside of the polar regions. Its survival depends on its elevation (), favorable terrain and a cool, moist, oceanic climate. The ice field has 28 exit glaciers, the largest two — San Quintin and San Rafael — nearly reach sea level to the west at the Pacific Ocean. Smaller exit glaciers, like San Valentín and Nef, feed numerous rivers and glacially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guayaneco Archipelago
The Guayaneco Archipelago () is an archipelago in southern Chile. It consists of 2 main islands, Wager Island (to the east), :es:Isla Byron (to the west), and many smaller islands. It was heavily glaciated during the most recent ice age. These glaciers dissected these mountain islands into a series of deep river valleys and glacial troughs. Today these glacial troughs are deep channels and fjords. The islands of the Guayaneco Archipelago comprise a series of elongated islands and deep bays that are the traces of a drowned coastal range. A number of deep channels are traversing generally north to south through the islands. These include the Messier Channel in the lower left portion of the image, and the Fallos Channel near the center of the image. Forests cover the lower slopes of the mountains throughout the many islands. Human settlement on these islands is scarce. History The archipelago is thought to have been a cohabitational contact zone between different canoe-faring in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caleta Tortel, Chile
Caleta Tortel is a coastal village () in Chile. It is the administrative center of the commune of Tortel and is located between the mouth of the Baker River the largest river in Chile and a small embayment of the Baker Channel. The surrounding geography is rugged, formed by a number of islands, fjords, channels and estuaries. The village was founded in 1955 to exploit the Guaytecas cypress ( Pilgerodendron uviferum) wood that was abundant in the area. The timber business accounts for most of the economy in Tortel to this day. Caleta Tortel consists mainly of stilt houses, typical of Chilotan architecture, built along the coast for several kilometers. There are no conventional streets - instead there are wooden walkways built with Guaitecas cypress. The wooden walkways give the village its distinctive look and its unique culture. Atlas viv ...

Endemic
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

Katalalixar National Reserve
Katalalixar National Reserve is a natural reserve located in an archipelago between Southern Patagonian Ice Field, and Northern Patagonian Ice Field in Aysén del General Carlos Ibáñez del Campo Region of Chile. The reserve was created in 1983 and has no infrastructure. It covers an area of within the Magellanic subpolar forests ecoregion and exhibits more biodiversity than other areas of southern Chile. This may appear contradictory, as the area is supposed to have been covered by the Patagonian Ice Sheet during the last glacial maximum An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers.

Southern Patagonian Ice Field
The Southern Patagonian Ice Field (), located at the Southern Patagonic Andes between Chile and Argentina, is the world's second largest contiguous extrapolar ice field. It is the bigger of two remnant parts of the Patagonian Ice Sheet, which covered all of southern Chile during the last glacial period, locally called the Llanquihue glaciation. Geography The Southern Patagonian Ice Field extends from parallels 48° 15′ S to 51° 30′ S for approximately , and has an approximate area of , of which belong to Chile and belong to Argentina. The ice mass feeds dozens of glaciers in the area, among which are the Upsala (), Viedma () and Perito Moreno () in the Los Glaciares National Park in Argentina, and the Pío XI Glacier or Bruggen Glacier (, the largest in area and longest in the southern hemisphere outside of Antarctica), O'Higgins (), Grey () and Tyndall () in Chile.
