Rhyolite Islands (Rhyolite Islands)
Rhyolite Islands (-69.66667°N, -68.58333°W) is a group of islands and rocks which extend 4 nautical miles (7 km) in an east–west direction, lying close off the Rymill Coast of Palmer Land opposite the north side of the mouth of Eureka Glacier, in George VI Sound. Surveyed in 1948 by Falkland Islands Dependencies Survey (FIDS) and so named from the rock of which the islands are largely composed. The name "Grupo Maipo," after the Chilean oil tanker Maipo, may refer to these islands roughly charted by the Chilean Antarctic Expedition, 1947, in about 6954S, 6833W.

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.
