The uplands include, in Western Australia, the Hamersley and Wunaamin-Miliwundi ranges in the western and north-western coastal areas and the Darling Range inland from Perth in the far south-west. The MacDonnell Ranges lie in the southern part of the Northern Territory and the Stuart and Musgrave Ranges are located in the north of the state of South Australia. Erosion and weathering have created striking, isolated rock formations called mesas or buttes in many parts of the shield, including the Kimberleys and Pilbara districts of Western Australia and Arnhem Land in the Northern Territory.
