Cliff
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fiftyone Glacier
Fiftyone Glacier is a large glacier flowing southwards, on the south side of Heard Island in the southern Indian Ocean. Its terminus is located between Lavett Bluff and Lambeth Bluff. To the northeast of Fiftyone Glacier is Winston Glacier, whose terminus is located at Winston Lagoon, between Cape Lockyer and Oatt Rocks. To the west of Fiftyone Glacier is Deacock Glacier, whose terminus is located between Cape Labuan and Long Beach. Discovery and naming Fiftyone Glacier was surveyed by ANARE ( Australian National Antarctic Research Expeditions) in 1948. It was named "The 1951 Glacier" by an ANARE party that made a traverse of Heard Island in 1951. The form Fiftyone Glacier was recommended by Antarctic Names Committee of Australia The Australian Antarctic Names and Medals Committee (AANMC) was established to advise the Government on names for features in the Australian Antarctic Territory and the subantarctic territory of Heard Island and the McDonald Islands.

Heard Island
The Territory of Heard Island and McDonald Islands (HIMI) is an Australian external territory comprising a volcanic group of mostly barren Antarctic islands, about two-thirds of the way from Madagascar to Antarctica. The group's overall size is in area and it has of coastline. Discovered in the mid-19th century, the islands lie on the Kerguelen Plateau in the Indian Ocean and have been an Australian territory since 1947. They contain Australia's only two active volcanoes. The summit of one, Mawson Peak, is higher than any mountain in all other Australian states or territories, except Dome Argus, Mount McClintock and Mount Menzies in the Australian Antarctic Territory. The islands are among the most remote places on Earth: They are located about southwest of Perth, southwest of Cape Leeuwin, Australia, southeast of South Africa, southeast of Madagascar, north of Antarctica, and southeast of the Kerguelen Islands (part of French Southern and Antarctic Lands).

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised.

Australian National Antarctic Research Expedition
The Australian National Antarctic Research Expeditions (ANARE ) is the historical name for the Australian Antarctic Program (AAp) administered for Australia by the Australian Antarctic Division (AAD). History Australia has had a long involvement in south polar regions since as early as Douglas Mawson's Australasian Antarctic Expedition in 1911. Further Australian exploration of the Antarctic continent was conducted during the British Australian and New Zealand Antarctic Research Expedition (BANZARE), which was conducted over the years 1929–1931. The Australian National Antarctic Research Expeditions were established in 1947 with expeditions to Macquarie Island and Heard Island. In 1948 the Australian Antarctic Division (AAD) was established to administer the expedition program. ANARE Name The name ANARE fell out of official use in the early 2000s. However current and former Australian Antarctic expeditioners continue to use the term informally as a means of identifica ...

John L
John Lasarus Williams (29 October 1924 – 15 June 2004), known as John L, was a Welsh nationalist activist. Williams was born in Llangoed on Anglesey, but lived most of his life in nearby Llanfairpwllgwyngyll. In his youth, he was a keen footballer, and he also worked as a teacher. His activism started when he campaigned against the refusal of Brewer Spinks, an employer in Blaenau Ffestiniog, to permit his staff to speak Welsh. This inspired him to become a founder of Undeb y Gymraeg Fyw, and through this organisation was the main organiser of ''Sioe Gymraeg y Borth'' (the Welsh show for Menai Bridge using the colloquial form of its Welsh name).Colli John L Williams , '''', 15 June ...

HMAS Labuan (L3501)
HMAS ''Labuan'' (L3501) (formerly HMA ''LST 3501'') was a Mark III Tank Landing Ship that served in the Royal Navy (as HMS ''LST 3501'') during World War II, and with the Royal Australian Navy (RAN) from 1946 until 1951. In RAN service, the landing ship was primarily used in support of the Australian National Antarctic Research Expedition (ANARE). The vessel transported ANARE personnel and equipment two and from Heard Island and Macquarie Island. While returning from Heard Island in 1951, ''Labuan'' broke down and had to be towed to the mainland. The ship was paid off, and disposed of in 1955. Design and construction ''LST 3501'' was built by Canadian Vickers at their shipyard in Montreal, Quebec, Canada.Gillett, ''Australian and New Zealand Warships since 1946'', p. 35 The vessel was launched on 31 August 1944. The Mark 3 LST had a light load displacement of , with a maximum beachable displacement of beaching. They were in length overall, with a beam of , and a maximum draugh ...
