Alph River (78°12′S 163°45′E / 78.2°S 163.75°E) is a small river, flowing in summertime, on the northern side of Koettlitz Glacier, Scott Coast, Antarctica. It rises from Koettlitz ice at the upper end of Pyramid Trough and from south to north includes Pyramid Ponds, Trough Lake, Walcott Lake, Howchin Lake, and Alph Lake.[1] The Alph ends in a subglacial stream beneath Koettlitz Glacier to McMurdo Sound.[2]
Exploration and name
[edit]The portion north of Pyramid Trough was explored and named in February 1911 by the British Antarctic Expedition (BrAE) Western Journey Party led by Thomas Griffith Taylor. He reported that the stream continues north a considerable distance under moraine and ultimately subglacially beneath Koettlitz Glacier to the Ross Sea. This led to the name from a passage in Samuel Taylor Coleridge's poem Kubla Khan: “Where Alph the sacred river ran, Through caverns measureless to man, Down to a sunless sea.”[1] The nearby Xanadu Hills are named from the same poem.[3]
