McMahon Islands (McMahon Islands)
McMahon Islands are two low, peaked, rocky islands, 0.5 nmi north of the Thala Hills, Enderby Land. The islands, about 60 m above sea level, are separated by a narrow channel. Plotted from Australian National Antarctic Research Expeditions (ANARE) air photos taken in 1956 and visited by the Australian National Antarctic Research Expeditions (ANARE) (Thala Dan) in February, 1961. Named by ANCA for F.P. McMahon, Supply Officer, Antarctic Division, Melbourne, and second-in-command of the Australian National Antarctic Research Expeditions (ANARE) (Thala Dan), 1960–61.

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.
