Alph River
river of Antarctica
Alph River (78.2°S 163.75°E / -78.2; 163.75 (Alph River)) 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.
The Alph ends in a subglacial stream beneath Koettlitz Glacier to McMurdo Sound.
Exploration and name
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."
The nearby Xanadu Hills are named from the same poem.

Why this record matters
“Alph River” is worth following because a concise public description often conceals a longer documentary argument. Here, Alph, River and river provides the most credible route into that argument.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Aug 2, 2026. The linked authority identifier is Q2840070. Authority coordinates are -78.200, 163.750. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1911 and 1994.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
