Karlu Karlu / Devils Marbles Conservation Reserve, Protected area near Wauchope, Australia.
Massive granite blocks in spherical form scatter across 18 square kilometers of protected territory, forming an extraordinary geological collection in the Australian Outback of Northern Territory.
John Ross named the rock formation in 1870 during the Australian Overland Telegraph Line expedition, followed by protected status in 1961 and official recognition of dual naming in 1980.
The Warumungu people preserve spiritual connections to this sacred landscape, where traditional narratives describe how Dreamtime beings shaped the granite formations during creation ceremonies.
Visitors find designated camping areas with basic facilities, marked walking trails, and information boards explaining geological processes. Access is via Stuart Highway, approximately 244 miles south of Darwin.
Temperature differences up to 72 degrees Fahrenheit between day and night cause rock expansion and contraction, splitting some blocks into nearly perfect halves while others remain in seemingly impossible balance despite erosion.
