Photographed by Hunting Aerosurveys Ltd. in 1955-57, and mapped from these photos by the Falkland Islands Dependencies Survey (FIDS). The name arose because the position of the point was only vaguely known when first visited by an FIDS sledge party in 1957, and it was obscured by thick fog from which it finally loomed like a phantom.

Piggott Peninsula (-73.71667°N, -61.33333°W) is a broad snow-covered peninsula between New Bedford Inlet and Wright Inlet on Lassiter Coast, Palmer Land, bounded to the west by Bryan Glacier and Swann Glacier. The feature was first seen from the air and photographed by the United States Antarctic Service (USAS) on December 30, 1940. It was mapped by United States Geological Survey (USGS) from surveys and U.S. Navy aerial photographs, 1961-67. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1985 after William R. Piggott, British ionospheriscist and Head, Atmospheric Sciences Division, British Antarctic Survey (BAS), 1973-79.

Pigmy Rock
Pigmy Rock (-68.71667°N, -67.55°W) is a rock lying close off the southwest side of Alamode Island at the south extremity of the Terra Firma Islands, off the west coast of Graham Land. The Terra Firma Islands were first visited and surveyed in 1936 by the British Graham Land Expedition (BGLE) under Rymill. This rock was surveyed in 1948 by the Falkland Islands Dependencies Survey (FIDS), who so named it because of its size.

Pila Island
Pila Island (-67.58333°N, 62.71667°W) is a small island 1.5 nautical miles (2.8 km) west of the Flat Islands in Holme Bay, Mac. Robertson Land. Mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936-37, and named Pila (the arrow). == See also == * List of antarctic and sub-antarctic islands

Pilarryggen
Pilarryggen (-72.7°N, -3.93333°W) is a rock ridge at the west side of Portalen Pass in the Borg Massif of Queen Maud Land. Mapped by Norwegian cartographers from surveys and air photos by Norwegian-British-Swedish Antarctic Expedition (NBSAE) (1949-52) and named Pilarryggen (the pillar ridge).
