Blood Falls. Blood Falls is an outflow of an iron (III) oxide –tainted plume of saltwater, flowing from the tongue of Taylor Glacier onto the ice-covered surface of West Lake Bonney in the Taylor Valley of the McMurdo Dry Valleys in Victoria Land, East Antarctica. Iron-rich hypersaline water sporadically emerges from small fissures in the ice ...
Taylor Glacier. The Taylor Glacier (77°44′S 162°10′E) is a glacier in Antarctica about 35 nautical miles (65 km; 40 mi) long, flowing from the plateau of Victoria Land into the western end of Taylor Valley, north of the Kukri Hills. [1] It flows to the south of the Asgard Range.

The McMurdo Dry Valleys are a row of largely snow-free valleys in Antarctica, located within Victoria Land west of McMurdo Sound. [ 1 ] The Dry Valleys experience extremely low humidity and surrounding mountains prevent the flow of ice from nearby glaciers. The rocks here are granites and gneisses, and glacial tills dot this bedrock landscape ...
A subglacial lake is a lake that is found under a glacier, typically beneath an ice cap or ice sheet. Subglacial lakes form at the boundary between ice and the underlying bedrock, where liquid water can exist above the lower melting point of ice under high pressure. [ 1 ][ 2 ] Over time, the overlying ice gradually melts at a rate of a few ...
Davis Station, pictured in 2005. Davis Station, commonly called Davis, is one of three permanent bases and research outposts in Antarctica managed by the Australian Antarctic Division (AAD). Davis is situated on the coast of Cooperation Sea in Princess Elizabeth Land, Ingrid Christensen Coast in the Australian Antarctic Territory, a territory ...
Elevation. 15 and 50 metres (50 and 160 ft) The Ross Ice Shelf is the largest ice shelf of Antarctica (as of 2013, an area of roughly 500,809 square kilometres (193,363 sq mi) [1] and about 800 kilometres (500 mi) across: about the size of France). [2] It is several hundred metres thick. The nearly vertical ice front to the open sea is more ...
