Mount Dixon, Heard Island
Mount Dixon () is a snow-covered stratovolcano, high, standing west of Anzac Peak on the Laurens Peninsula, Heard Island. The feature appears to have been roughly charted on an 1860 sketch map by Captain H.C. Chester, an American sealer operating in the area during this period. It was surveyed in 1948 by the Australian National Antarctic Research Expeditions (ANARE), and named by them for Lieutenant Commander George M. Dixon, RANVR, commanding officer of HMAS ''Labuan'' which landed and relieved the 1948 and 1949 ANARE parties. The peak is northwest of Big Ben Big Ben is the nickname for the Great Bell of the Great Clock of Westminster, at the north end of the Palace of Westminster in London, England, and the name is frequently extended to refer also to the clock and the clock tower.

Stratovolcano
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of volcanoes, in contrast to the less common shield volca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anzac Peak
Anzac Peak is a volcano on the Laurens Peninsula of Heard Island in the Southern Ocean. It lies to the northwest of Mawson Peak. Despite its low elevation of just over 700 metres high, the peak and several neighbouring peaks have permanent snow and ice, like the Jacka Glacier with several icefalls.Google Earth images.

Laurens Peninsula
Laurens Peninsula () is a rugged peninsula surmounted by several ice-covered peaks that forms the northwestern part of Heard Island in the southern Indian Ocean. The name was applied by the Australian National Antarctic Research Expedition following their survey in 1948. It derives from the existing name Cape Laurens, applied for the northwestern extremity of this peninsula after the American bark ''Laurens'' which, under Captain Franklin F. Smith, visited Heard Island in 1855–56 and assisted in initiating sealing operations there. A small hill called Macey Cone sits at the northwest end of the peninsula.

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).

Global Volcanism Program
The Smithsonian Institution's Global Volcanism Program (GVP) documents Earth's volcanoes and their eruptive history over the past 10,000 years. The mission of the GVP is to document, understand, and disseminate information about global volcanic activity. Global Volcanism Program Database The GVP gathers information and reports on current eruptions from around the world, and maintains a database repository on active volcanoes, their eruptions and their eruption histories. In this way, a global context for the planet's active volcanism is presented. Smithsonian reporting on current volcanic activity dates back to 1968, with the Center for Short-Lived Phenomena (CSLP). The GVP is housed in the Department of Mineral Sciences, part of the National Museum of Natural History, on the National Mall in Washington, D.C. During the early stages of an eruption, the GVP acts as a clearing house of reports, data, and imagery which are accumulated from a global network of contributors. The ...

Smithsonian Institution
The Smithsonian Institution ( ), or simply the Smithsonian, is a group of museums and education and research centers, the largest such complex in the world, created by the U.S. government "for the increase and diffusion of knowledge". Founded on August 10, 1846, it operates as a trust instrumentality and is not formally a part of any of the three branches of the federal government. The institution is named after its founding donor, British scientist James Smithson. It was originally organized as the United States National Museum, but that name ceased to exist administratively in 1967. Called "the nation's attic" for its eclectic holdings of 154 million items, the institution's 19 museums, 21 libraries, nine research centers, and zoo include historical and architectural landmarks, mostly located in the District of Columbia. Additional facilities are located in Maryland, New York, and Virginia. More than 200 institutions and museums in 45 states,States without Smithsonian ...

Australian National Antarctic Research Expeditions
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 ...

RANVR
Royal Australian Naval Volunteer Reserve (RANVR) was a reserve force of the Royal Australian Navy. Formation In late 1920, the Navy Board proposed the creation of an Royal Australian Naval Volunteer Reserve scheme, with approaches made to yachting and rowing clubs, starting in New South Wales, South Australia, Victoria, and Tasmania. Men who were undergoing or liable to compulsory training under the ''Defence Act'' (Cwlth) were ineligible for enrolment. For the volunteers, a period of five years of service was proposed with parading twice a month, training occur outside of business hours, entry as an able seaman rating, and officer appointments not based on social or other positions. Requirements later included fourteen days training every alternate year, and 'seven days out of this period should be spent afloat'. By 1925, following mufti attire on parades, the uniform was determined to be the same as the regular forces, with 'RANVR' replacing 'RANR' on the cap band, and th ...

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.

Volcanoes Of Heard Island And McDonald Islands
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide pa ...
