The Yorke Peninsula is a peninsula located northwest and west of Adelaide in South Australia, between Spencer Gulf on the west and Gulf St Vincent on the east. The peninsula is separated from Kangaroo Island to the south by Investigator Strait. The most populous town in the region is Kadina. History Prior to European settlement of the area commencing around 1840, following the British colonisation of South Australia, Yorke Peninsula was the home to the Narungga people. This Aboriginal Australian nation are the traditional owners of the land, and comprised four clans sharing the peninsula, known as Guuranda: Kurnara in the north, Dilpa in the south, Wari in the west and Windarra in the east. Today the descendants of these people still live on Yorke Peninsula, supported by the Narungga Aboriginal Progress Association in Maitland, and in the community at Point Pearce. It was named “Yorke’s Peninsula” by Captain Matthew Flinders, after Charles Philip Yorke (later Lord Hardwicke), narrowly beating French navigator Captain Nicolas Baudin, who preferred the name “Cambaceres Peninsula”. Geography Physiography The area is also known as the Yorke Horst, which is distinct physiographic section of the larger South Australian Shatter Belt province, which in turn is part of the larger West Australian Shield, a physiographic division describing a geological feature known as a shield. Along with Cape Eyre the peninsula is also part of the Eyre Yorke Block bioregion. Topography Most of Yorke Peninsula is prime agricultural land, with mostly small rolling hills and flat plains. The southern end of the Hummocks Range partially extends down the top of the Peninsula, flattening out near Clinton. The highest point on the Peninsula is north-east of Maitland, although there is some debate as to where the Peninsula borders the Mid-North, and part of the steep Hummocks terrain may be considered part of the Peninsula. A series of shallow valleys line the interior of the Peninsula, with the main one called the Yorke Valley extending roughly from Sunnyvale, south of Paskeville through to Ramsey, between Minlaton and Stansbury. The predominant Yorke Valley area lies roughly in the area between Arthurton, Maitland, Ardrossan and Curramulka. The southern tip, sometimes termed the "foot", is surrounded on three sides by the ocean, and forms a isolated "mainland island", with large tracts of excellent native vegetation. Towns Principal towns include the Copper Coast towns of Kadina, Moonta and Wallaroo; farming centres of Maitland, Minlaton
