Gnarlbine Rock is a granite rock[1] located approximately 492 km (306 mi) east of Perth and approximately 30 km (19 mi) southwest of Coolgardie in the Goldfields-Esperance region of Western Australia.
[4] The rock is located along the Holland Track between Broomehill and Coolgardie and has camp sites available.
[2] The waterhole on the eastern side of the rock was also important to Indigenous Australian peoples as a water source.
[5] Charles Cooke Hunt camped by the rock in 1864, noting that the water might prove useful.
Gilles McPherson, an explorer and prospector, was saved by an Aboriginal named Toobey in 1888, who brought him to the well after he could find no water.
