Garnet Hill
Garnet Hill () is a rocky hill, high, rising above the east side of McLeod Glacier in the south part of Signy Island, in the South Orkney Islands. It forms the south end of a line of rock and ice cliffs which separate McLeod Glacier from Orwell Glacier. It was so named by the Falkland Islands Dependencies Survey, following their survey of 1947, because of the abundance of garnet Garnets () are a group of silicate minerals that have been used since the Bronze Age as gemstones and abrasives.

McLeod Glacier (South Orkney Islands)
McLeod Glacier is a glacier long, flowing in a southeasterly direction into Clowes Bay on the south side of Signy Island, in the South Orkney Islands off Antarctica. It was named by the UK Antarctic Place-Names Committee in 1954 for Michael McLeod (explorer), Michael McLeod, following a survey by the Falkland Islands Dependencies Survey in 1947. On December 12, 1821, the cutter ''Beaufoy'' under McLeod sailed to a position at least west of the South Orkney Islands, where a chart annotation indicates that land was sighted, possibly Coronation Island.

Signy Island
Signy Island is a small subantarctic island in the South Orkney Islands of Antarctica. It was named by the Norwegian whaler Petter Sørlle (1884–1933) after his wife, Signy Therese. The island is about long and wide and rises to above sea level. Much of it is permanently covered with ice. The average temperature range is to about in winter (i.e. in July). The extremes extend to . It is separated from Coronation Island to the north by Normanna Strait, and from Moe Island to the southwest by Fyr Channel. On Signy Island, the British Antarctic Survey (BAS) maintains the Signy Research Station, a scientific station for research in biology. The base was opened on 18 March 1947, on the site of an earlier whaling station that had existed there in the 1920s. The station was staffed year-round until 1996; since that year it has been occupied only from November to April. It houses 10 people.

Orwell Glacier
Orwell Glacier () is a small glacier, less than 0.5 nautical miles (0.9 km) long, which descends steeply from the south slopes of Snow Hills and terminates in 20 m ice cliffs along the south margin of Elephant Flats in the east part of Signy Island, in the South Orkney Islands. Surveyed by DI personnel in 1927 and named by them for the Norwegian transport throughout the seasons 1925–26 to 1929–30. Resurveyed by the Falkland Islands Dependencies Survey (FIDS) in 1947.

Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office. At the end of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garnet
Garnets () are a group of silicate minerals that have been used since the Bronze Age as gemstones and abrasives. All species of garnets possess similar physical properties and crystal forms, but differ in chemical composition. The different species are pyrope, almandine, spessartine, grossular (varieties of which are hessonite or cinnamon-stone and tsavorite), uvarovite and andradite. The garnets make up two solid solution series: pyrope-almandine-spessartine (pyralspite), with the composition range ; and uvarovite-grossular-andradite (ugrandite), with the composition range . Etymology The word ''garnet'' comes from the 14th-century Middle English word ''gernet'', meaning 'dark red'. It is borrowed from Old French ''grenate'' from Latin ''granatus,'' from ''granum'' ('grain, seed'). This is possibly a reference to ''mela granatum'' or even ''pomum granatum'' ('pomegranate', ''Punica granatum''), a plant whose fruits contain abundant and vivid red seed covers ( arils), whic ...
