Twig Rock (Twig Rock)
Twig Rock (-68.7°N, -67.53333°W) is a small rocky mass, more than 90 m high, between Alamode Island and Hayrick Island in 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. Twig Rock was surveyed in 1948 by the Falkland Islands Dependencies Survey (FIDS), who so named it because of the branching nature of the dike system exposed on its north face.

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.
