28-514: Dudley Peninsula (known as Presquila Gallissoniere and as the MacDonnell Peninsula from 1857 to 1986) is the peninsula forming the eastern end of Kangaroo Island in the Australian state of South Australia . It was occupied by Aboriginal Australians as recently as 3,100 years BP but was found to be unoccupied by the first European explorers to visit it in the early 19th century. It

56-613: A fleet under the control of the South Australian Company arriving at what is now Kingscote further west on Kangaroo Island. Some of the people who had been living on that part of Kangaroo Island prior to 1836 moved to the peninsula to avoid being within the jurisdiction of the South Australian Company and thereby making it "most prosperous part of the island and the scene of its first significant agricultural and pastoral development." The full extent of Kangaroo Island

84-677: A site called Pigs Waterhole on the peninsula suggest aboriginal presence in the eastern end of Kangaroo Island as recently as 3,100 years BP. Dudley Peninsula was first visited by European navigators in 1802 when the British navigator, Matthew Flinders , explored its north coast during March 1802. After meeting Flinders at Encounter Bay in April 1802, the Baudin expedition visited the peninsula's north coast later in April 1802 and explored its south coast during January 1803. Formal settlement commenced in 1836 with

112-531: The coast of the mainland. The council was formed on the 28 November 1996 by the amalgamation of the District Council of Kingscote and the District Council of Dudley . Its first meeting held on 11 December 1996. The seat of the council is located in the island's largest town, Kingscote . The district's population at the 2016 census was approximately 4,700. Mayor : Michael Pengilly CEO : Greg Georgopoulos Councillors : The district's economy

140-495: The "MacDonnell Peninsula" by William Bloomfield Douglas after Richard Graves MacDonnell , the sixth governor of South Australia . On 20 March 1986, it was renamed as the "Dudley Peninsula" to be "in keeping with local usage." The archaeological record indicates that Kangaroo Island was occupied by Aboriginal Australians as early as 16,110 years BP. European explorers visiting in the early 19th century found no evidence of human occupation as evident by lack of smoke from fires which

168-558: The 16th century. A peninsula is generally defined as a piece of land surrounded on most sides by water. A peninsula may be bordered by more than one body of water, and the body of water does not have to be an ocean or a sea. A piece of land on a very tight river bend or one between two rivers is sometimes said to form a peninsula, for example in the New Barbadoes Neck in New Jersey , United States. A peninsula may be connected to

196-534: The coastal perimeter with exception to some parts of the Nepean Bay coastline and by residential use. The peninsula is served by a road network extending from both Penneshaw on its northern coast and from Hog Bay Road, a road maintained by the South Australian Government . Hog Bay Road which follows the peninsula's north-western coastline connects Penneshaw and the settlements overlooking Nepean Bay with

224-652: The east to Strawbridge Point at the junction of American River and Eastern Cove in the west had been progressively cleared for agricultural purposes, while the southern side had retained most of its native vegetation. Subsequent clearing of native vegetation on a broadacre scale ceased in 1990 with the proclamation of the Native Vegetation Act 1990 . As of 2014, majority of the land on the Dudley Peninsula has been zoned by law for agricultural use (i.e. "primary production") followed by conservation including most of

252-400: The end of the last ice age . The peninsula has a plateau covering its northern half with a maximum height of about 150 metres (490 ft) while the southern half has a maximum height in the order of 100 metres (330 ft). Its coastline consists of a cliff-line in the order of 40 metres (130 ft) to 70 metres (230 ft) in height with the exception of sandy bays such as Nepean Bay in

280-544: The extent of the Dudley Peninsula with the nearest and the only one available being the Kingscote Airport on the western part of the island in the locality of Cygnet River . The Dudley Peninsula is located within the jurisdiction of the Kangaroo Island Council and within the following electorates – the state district of Finniss and the federal division of Mayo . As of 2015, the Dudley Peninsula contained

308-533: The following conservation parks – Baudin , Cape Willoughby , Dudley , Lashmar , Lesueur , Pelican Lagoon and Simpson . Also, as of 2015, an area of privately owned land appropriately equivalent to that of the above conservation parks has protected status due to being subject to native vegetation heritage agreements . Peninsula The word peninsula derives from Latin paeninsula , from paene  'almost' and insula  'island'. The word entered English in

336-489: The formation of a peninsula. For example, in the case of Florida , continental drift, marine sediment, and marine transgressions were all contributing factors to its shape. In the case of formation from glaciers (e.g., the Antarctic Peninsula or Cape Cod ), peninsulas can be created due to glacial erosion , meltwater or deposition . If erosion formed the peninsula, softer and harder rocks were present, and since

364-466: The glacier only erodes softer rock, it formed a basin . This may create peninsulas, and occurred for example in the Keweenaw Peninsula . In the case of formation from meltwater, melting glaciers deposit sediment and form moraines , which act as dams for the meltwater. This may create bodies of water that surround the land, forming peninsulas. If deposition formed the peninsula, the peninsula

392-501: The mainland via an isthmus , for example, in the Isthmus of Corinth which connects to the Peloponnese peninsula. DON'T FORGET OR ELSE Peninsulas can be formed from continental drift , glacial erosion , glacial meltwater , glacial deposition , marine sediment , marine transgressions , volcanoes, divergent boundaries or river sedimentation. More than one factor may play into

420-638: The north-east by Backstairs Passage from Kangaroo Head in the west to Cape Willoughby in the east and to the south by the body of water known in Australia as the Southern Ocean and by international authorities as the Great Australian Bight . The first reported European name for the Dudley Peninsula is "Presquila Gallissoniere" which was given by the Baudin Expedition . In 1857, it was named

448-477: The north-west coast, Antechamber Bay in the north east coast and Pennington Bay on the south-west coast. The peninsula has a geological basement of Tapanappa Formation sandstones (from the Kanmantoo Group ) which were laid during the early Cambrian period . The basement stratum has undergone extensive erosion to create laterite based soil which covers the northern half of the peninsula. The southern half of

476-464: The peninsula has a Bridgewater Group limestone which was laid over the basement stratum during the Pleistocene and which has eroded to form a dune field. The Dudley Peninsula has a mediterranean climate ( Köppen climate classification Csb) As of 2002, Penneshaw received an annual rainfall of 509 millimetres (20.0 in) and this average is considered to increase to 600 millimetres (24 in) at

504-470: The remaining 319 located on the remainder of the peninsula, being the localities of American Beach , Antechamber Bay , Baudin Beach , Brown Beach , Cuttlefish Bay , Dudley East , Dudley West , Ironstone , Island Beach , Kangaroo Head , Pelican Lagoon , Porky Flat , Sapphiretown , Willoughby and Willson River . As of 1989, most of the northern side of the peninsula above a line from Cape Willoughby in

532-468: The sediment is deposited, forming a delta peninsula. Marine transgressions (changes in sea level) may form peninsulas, but also may affect existing peninsulas. For example, the water level may change, which causes a peninsula to become an island during high water levels. Similarly, wet weather causing higher water levels make peninsulas appear smaller, while dry weather make them appear larger. Sea level rise from global warming will permanently reduce

560-502: The size of some peninsulas over time. Peninsulas are noted for their use as shelter for humans and Neanderthals . The landform is advantageous because it gives hunting access to both land and sea animals. They can also serve as markers of a nation's borders. Kangaroo Island Council The Kangaroo Island Council is a local government area in South Australia that covers the entirety of Kangaroo Island , 13 km off

588-466: The top of the peninsula's plateau. Settlements on the Dudley Peninsula consist of Penneshaw which overlooks Backstairs Passage on the north coast with the following being located on the north west coast overlooking Nepean Bay (from east to west) – Baudin Beach , Island Beach and Sapphiretown . At the 2011 census , the Dudley Peninsula had a population of 595 with 276 persons located in Penneshaw and

616-482: The town of Kingscote and the rest of Kangaroo Island. As of 2014, port infrastructure at Penneshaw was being used by Kangaroo Island SeaLink who operates the ferry service between Penneshaw and Cape Jervis on the South Australian mainland. Navigation aids located on the peninsula's coast include lighthouses at both Cape St Albans and Cape Willoughby . As of 2014, no public airfields were located within

644-552: The volcano erupts near shallow water. Marine sediment may form peninsulas by the creation of limestone . A rift peninsula may form as a result of a divergent boundary in plate tectonics (e.g. the Arabian Peninsula ), while a convergent boundary may also form peninsulas (e.g. Gibraltar or the Indian subcontinent ). Peninsulas can also form due to sedimentation in rivers. When a river carrying sediment flows into an ocean,

672-465: Was common along the Australian coastline at the time, overgrown vegetation that had not been managed by "firestick farming" and animals such as seals and kangaroos "appeared unused to human presence". Aboriginal sites have been identified by the South Australian Museum and others on the Dudley Peninsula. As of 1999, radiocarbon dating of material recovered via archaeological excavation from

700-538: Was composed of sedimentary rock , which was created from a large deposit of glacial drift . The hill of drift becomes a peninsula if the hill formed near water but was still connected to the mainland, for example during the formation of Cape Cod about 23,000 years ago. In the case of formation from volcanoes, when a volcano erupts magma near water, it may form a peninsula (e.g., the Alaskan Peninsula ). Peninsulas formed from volcanoes are especially common when

728-453: Was first settled by Europeans as early as the 1830s. As of 2011, it had a population of 595 people. Dudley Peninsula is the eastern end of Kangaroo Island. It is connected to the main body of the island via an isthmus which itself forms the southern side of Pelican Lagoon . The peninsula is bounded to the west by Pelican Lagoon, American River and Eastern Cove all within Nepean Bay , to

756-583: Was gazetted on 13 August 1874 as the cadastral division known as the County of Carnarvon simultaneously with the creation of another cadastral division, the Hundred of Dudley , which covers the full extent of what is now the Dudley Peninsula. In 1875, land in the Hundred of Dudley near the north coast of the peninsula was surveyed and given freehold title in response for the demand for agricultural land. The town of Penneshaw

784-428: Was proclaimed on 12 January 1882. On 7 June 1888, the local government area of the District Council of Dudley was established. This was subsequently merged in 1996 with the District Council of Kingscote to create the Kangaroo Island Council . The Dudley Peninsula came into existence about 9,500 years BP when Kangaroo Island became separate from what is now Fleurieu Peninsula due to the rise in sea level following
