What is Endorheic basin?
{{Redlinks}} An '''endorheic basin''', also called an '''internal drainage system''', is a drainage [[Basin (geology)|basin]], or [[watershed]], that does not flow to one of the Earth's major [[ocean]]s. This is unlike normal basins that collect in [[river]]s and flow to the ocean. Endorheic basins usually end in a saline [[lake]] or a salt flat. They can be found in all parts of the world, but usually in [[desert]] locations.<ref>{{cite web|url=http://www.economicexpert.com/a/Endorheic.htm|title=Home>Endorheic|accessdate=2009-04-01|archive-date=2008-10-13|archive-url=https://web.archive.org/web/20081013080552/http://www.economicexpert.com/a/Endorheic.htm|url-status=dead}}</ref> ==List of major endorheic basins== [[Image:Ocean drainage.png|600px|thumb|center|Major endorheic basins of the world. Endorheic basins are shown in dark gray; major endorheic lakes are shown in black.]] ===Antarctica=== Endorheic lakes in Antarctica are located in the [[McMurdo Dry Valleys]], [[Victoria Land]], [[Antarctica]], the largest ice-free area in Antarctica. *[[Don Juan Pond]] in [[Wright Valley]] is fed by groundwater from a rock glacier and remains unfrozen throughout the year. *[[Lake Vanda]] in [[Wright Valley]] has a perennial ice cover, the edges of which melt in the summer allowing flow from the longest river in Antarctica, the [[Onyx River]]. The lake is over 70 m deep and is hypersaline. *[[Lake Bonney (Antarctica)|Lake Bonney]] is in [[Taylor Valley]] and has a perennial ice over and two lobes separated by the Bonney Riegel. The lake is fed by glacial melt and discharge from [[Blood Falls]]. Its unique glacial history has resulted in a hypersaline brine in the bottom waters and fresh water at the surface. *[[Lake Hoare]], in [[Taylor Valley]], is the freshest of the Dry Valley lakes receiving its melt almost exclusively from the Canada Glacier. The lake has an ice cover and forms a moat during the Austral summer. *[[Lake Fryxell]], in adjacent to the [[Ross Sea]] in [[Taylor Valley]]. The lake has an ice cover and re
