Macey Cone

	Macey Cone Macey Cone () is a small hill, high, which marks the remnants of an extinct volcanic cone surmounting the lava cliffs at the northwest end of Laurens Peninsula, about northeast of Cape Laurens at the northwest end of Heard Island. The feature was surveyed in 1948 by the 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).

picture info	Volcanic Cone Volcanic cones are among the simplest volcanic landforms. They are built by ejecta from a volcanic vent, piling up around the vent in the shape of a cone with a central crater. Volcanic cones are of different types, depending upon the nature and size of the fragments ejected during the eruption. Types of volcanic cones include stratocones, spatter cones, tuff cones, and cinder cones. Stratocone Stratocones are large cone-shaped volcanoes made up of lava flows, explosively erupted pyroclastic rocks, and igneous intrusives that are typically centered around a cylindrical vent. Unlike shield volcanoes, they are characterized by a steep profile and periodic, often alternating, explosive eruptions and effusive eruptions. Some have collapsed craters called calderas. The central core of a stratocone is commonly dominated by a central core of intrusive rocks that range from around to over several kilometers in diameter. This central core is surrounded by multiple generations of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	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.

	Cape Laurens Cape Laurens () is a cape which marks the northwestern extremity of Laurens Peninsula and Heard Island. The name was probably applied by Captain Franklin F. Smith, of the American bark ''Laurens'', who visited Heard Island in 1855–56 and who, with Captain Erasmus Darwin Rogers, initiated sealing operations and longtime American sealer occupation of Heard Island. The name appears on a chart by the British expedition under George Nares Vice-Admiral Sir George Strong Nares (24 April 1831 – 15 January 1915) was a Royal Navy officer and Arctic explorer. He commanded the ''Challenger'' Expedition, and the British Arctic Expedition.

picture info	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).

picture info	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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
