The George Gill Range is located south-west of the Greater MacDonnell Ranges and 215 km west-southwest of Alice Springs. The Range is a large block of sandstone with a spectacular canyon (Watarrka or Kings Canyon) rising up to 270m from Kings Creek on its western end. The southern face of the range is cut by several gorges containing springs and waterholes.
Kings Creek flows south-west from the range into the Great Sandy Desert and Kings Creek floodout swamps. Major vegetation communities include spinifex grasslands with an overstorey of mixed open woodland, chenopod and mulga shrublands, and pockets of moisture-dependant species in sheltered gullies.
