Seller Glacier is a well-defined glacier, 20 nautical miles (37?km) long and 4 nautical miles (7?km) wide flowing westward into Forster Ice Piedmont, western Antarctic Peninsula, just north of Flinders Peak. Roughly surveyed by British Graham Land Expedition (BGLE), 1936–37, and resurveyed by Falkland Islands Dependencies Survey (FIDS) in December 1958.
