Ninety-eight percent of Antarctica is covered by an ice sheet, so rivers are seasonal, melt-water formations.
According to its Wikipedia entry:
"Alph River is a small river of Antarctica, running into Walcott Bay, Victoria Land. It is located in an ice-free region at the west of the Koettlitz Glacier, Scott Coast. The Alph emerges from Trough Lake, and flows through Walcott Lake, Howchin Lake, and Alph Lake. It ends in a sub-glacial flow beneath Koettlitz Glacier to McMurdo Sound."
