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 ...
Jill Mikucki. Jill Ann Mikucki is an American microbiologist, educator and Antarctic researcher, best known for her work at Blood Falls demonstrating that microbes can grow below ice in the absence of sunlight. [1][2] She is a leader of international teams studying ecosystems under the ice. [3]

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 ...
Taylor Valley77°37′S163°00′E / 77.617°S 163.000°E is an ice-free valley about 18 nautical miles (33 km; 21 mi) long, once occupied by the receding Taylor Glacier. It lies north of the Kukri Hills between the Taylor Glacier and New Harbour in Victoria Land, Antarctica. [ 1 ]
