All other subranges of Antarctica Ranges 11. So named by the Southern Party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE) (1961–62) because it was at this landfall that the party arrived after their first crossing of Mill Glacier in November 1961. The lunar meteorites were recovered from icefields near the Dominion Range (DOM) of the Transantarctic Mountains, roughly 400 kilometers (250 miles) from the South Pole.
