Clarsach Glacier
Clarsach Glacier () is a glacier flowing south between Prague Spur and the Finlandia Foothills in northern Alexander Island, Antarctica. The feature was photographed from the air by the Ronne Antarctic Research Expedition, 1947–48, and was mapped from these photographs by D. Searle of the Falkland Islands Dependencies Survey, 1960. Further delineation was made from U.S. Navy aerial photographs taken 1966–67 and from U.S. Landsat imagery taken January 1974. It was so named by the UK Antarctic Place-Names Committee, 1977, due to the resemblance its profile shares with a clàrsach The Celtic harp is a triangular frame harp traditional to the Celtic nations of northwest Europe.

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Prague Spur
Prague Spur () is a rock spur rising to about 500 m between Puccini Spur and the Finlandia Foothills, at the east end of the Mozart Ice Piedmont, situated in the northern portion of Alexander Island, Antarctica. Photographed from the air by Ronne Antarctic Research Expedition (RARE), 1947–48, and mapped from these photographs by D. Searle of Falkland Islands Dependencies Survey (FIDS), 1960. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) in 1977 in association with the Mozart Ice Piedmont and Wolfgang Amadeus Mozart's Symphony No. 38, the "Prague", composed in late 1786.

Finlandia Foothills
The Finlandia Foothills () are a rock massif, long and wide, rising to about at the west side of Sibelius Glacier, situated in northern Alexander Island, Antarctica. The massif lies immediately south of the Geode Nunataks, north of the Handel Ice Piedmont and west of Witches Cauldron. They were photographed from the air by the Ronne Antarctic Research Expedition, 1947–48, and mapped from these photographs by D. Searle of the Falkland Islands Dependencies Survey, 1960. In association with the glacier they were named after the symphonic poem ''Finlandia'' by the Finnish composer Jean Sibelius Jean Sibelius ( ; ; born Johan Julius Christian Sibelius; 8 December 186520 September 1957) was a Finnish composer of the late Romantic and 20th-century classical music, early-modern periods.

Alexander Island
Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west.Stewart, J. (2011) ''Antarctic An Encyclopedia'' McFarland & Company Inc, New York. 1776 pp. . Alexander Island is about long in a north–south direction, wide in the north, and wide in the south. Alexander Island is the second-largest uninhabited island in the world, after Devon Island. History Alexander Island was discovered on January 28, 1821, by a Russian expedition under Fabian Gottlieb von Bellingshausen, who named it Alexander I Land for the reigning Tsar Alexander I of Russia.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . 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 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 . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer.

Ronne Antarctic Research Expedition
The Ronne Antarctic Research Expedition (RARE) was an expedition from 1947–1948 which researched the area surrounding the head of the Weddell Sea in Antarctica. Background Finn Ronne led the RARE which was the final privately sponsored expedition from the United States and explored and mapped the last unknown coastline on earth and determined that the Weddell Sea and the Ross Sea were not connected. The expedition included Isaac Schlossbach, as second in command, who was to have Cape Schlossbach named after him. The expedition, based out of Stonington Island was the first to take women to over-winter. Ronne's wife, Edith Ronne was correspondent for the North American Newspaper Alliance for expedition and the chief pilot Darlington took his wife.
