Mount Olsen (California)
Mount Olsen () is a snow-covered peak (635 m) standing 0.2 nautical miles (0.4 km) east of Hayter Peak on Laurens Peninsula, in the northwest part of Heard Island. The feature appears to have been roughly charted on an 1860 sketch map compiled by Captain H.C. Chester, American sealer operating in the area during this period. It was surveyed in 1948 by ANARE (Australian National Antarctic Research Expeditions), who named it for Bjarne Olsen, first mate on the whale catcher Kidalkey which visited the island An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island ... in January 1929. It is close to and north of the Gilchrist Aiguilles.

Summit (topography)
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary ...

Hayter Peak
Hayter Peak () is a peak, 565 meters (1,850 ft) high, standing 400 meters west of Mount Olsen along the back of the Laurens Peninsula and at the northwest end of Heard Island. The peak was first surveyed in 1948 by the Australian National Antarctic Research Expeditions, and named by them for Alfred J. Hayter, a warrant officer Warrant officer (WO) is a rank or category of ranks in the armed forces of many countries. Depending on the country, service, or historical context, warrant officers are sometimes classified as the most junior of the commissioned ranks, the mos ... on the expedition ship HMAS ''Labuan'' (L3501).

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).

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 ...

Island
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
