Narien Range

The Narien Range (also known as Mount Lock Range, the Mannanarie Hills or Tarcowie Hills) is a range of hills in South Australia's Mid North. The range stretches from a point north of Jamestown northwards to Orroroo.

The south-western slopes are home to the Hornsdale Wind Farm.

The name Narien is officially thought to be derived from John Narrien (1782-1860), a mathematics master who taught George Grey, Governor of South Australia in 1851 at the time of the first recorded use of the name.
