Petermann Ranges

Low mountains extending for 200 miles (320 km) from east-central Western Australia southeast to the southwest corner of Northern Territory. A continuation of the granite and gneiss formations in the Musgrave Ranges to the southeast, the Petermanns rise to a height of 3,800 feet (1,158 metres). Visited (1874) by Ernest Giles, the mountains were named after August Petermann, a German geographer.
