Yarrangobilly Caves

The Yarrangobilly Caves are located in a 12-kilometre-long (7.5 mi) karst region along the Yarrangobilly River valley in the north of Kosciuszko National Park, New South Wales, Australia.

Discovered to British colonists by a cattleman, the Yarrangobilly Caves system includes several independent limestone caves formed over different time periods, from several million to a few hundred thousand years old.

The caves are administered by the National Parks and Wildlife Service.

The cave was formed in 440-million-year-old limestone, and was first discovered by Europeans in 1834 when a stockman John Bowman came across the complex.

[7] Jersey Cave is noted for its rare displays of black and grey flowstone, coloured by ash from ancient bushfires.
