Blue Glacier (Antarctica)

(Redirected from Covert Glacier)

Blue Glacier (77°50′S 164°10′E / 77.833°S 164.167°E / -77.833; 164.167 (Blue Glacier)) is a large glacier which flows into Bowers Piedmont Glacier about 10 nautical miles (19 km; 12 mi) south of New Harbour, in Victoria Land, Antarctica. It was discovered by the British National Antarctic Expedition (BrNAE) under Robert Falcon Scott, 1901–04, who gave it this name because of its clear blue ice at the time of discovery.[1]

Blue Glacier rises to the north of Armitage Saddle, and flows north. The coastal range that borders the lower Koettlitz Glacier and the McMurdo Ice Shelf lies to the east, and the Royal Society Range is to the west. In its lower section the Blue Glacier turns to the east and joins the Bowers Piedmont Glacier on the west coast of the McMurdo Sound.[2][3]

Left tributary glaciers

edit

Glaciers entering from the left (west) flowing from the Royal Society Range, include (from south to north) Salient, Hooker, Mitchell, Spring, Covert, Amos Glacier and Geoid Glacier.
