Gillock Island (Gillock Island)
Gillock Island is an ice-covered island, 20 nmi long and 2 to 6 nmi wide, with numerous rock outcrops exposed along its flanks. It is aligned north–south and lies in the eastern part of Amery Ice Shelf.
Delineated in 1952 by John H. Roscoe from air photos taken by U.S. Navy Operation Highjump (1946–47). Named by him for Lieutenant Robert A. Gillock, U.S. Navy, navigator on Operation Highjump photographic flights over this and other coastal areas between 14°E and 164°E.
The Bain Crags (-70.5°N, 71.75°W) are a number of rock exposures, many of which are banded, in the face of or projecting from the ice cliffs along the south part of the west side of Gillock Island. The feature was visited in January 1969 by J.H.C. Bain, geologist with the Australian National Antarctic Research Expeditions Prince Charles Mountains survey party, after whom it is named.

Country - Antarctica
Antarctica is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14200000 km2. Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km.
Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over 200 mm along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost 60 m. Antarctica holds the record for the lowest measured temperature on Earth, −89.2 C. The coastal regions can reach temperatures over 10 C in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation occurs, it is mostly in the form of lichen or moss.
