Koonalda Cave is a cave in the Australian state of South Australia, on the Nullarbor Plain in the locality of Nullarbor. It is notable as an archeological site.[2][3]
I.D. Lewis described the cave in 1976 as:[1]
Large doline 60m in diam. and 25m deep; talus slope to two main large passages connected by a high window; total length of cave 1200m; three lakes at -80m; narrow airspace beyond third lake leads to 45m diam. dome and lake; another 30m sump leads off this...
Thousands of square metres in the cave are covered in parallel finger-marked geometric lines and patterns, Indigenous Australian artwork which has been dated as 20,000 years old.[2][4] It is located about 99 kilometres (62 mi) west of the Nullarbor roadhouse[1] and about 97 kilometres (60 mi) north east from Eucla[5] within the Nullarbor Wilderness Protection Area.[6]
The cave was abandoned 19,000 years ago, and rediscovered by archeologists in 1956.[4]
The cave was explored by an expedition led by Captain J. M. Thompson in 1935. The team entered the cave by a ladder and found themselves in a chamber some 244 metres (800 ft) in circumference and walked down tunnels over 366 metres (1,200 ft) in length.[5]
In the 1960s, the cave was excavated by Alexandor Gallus, who found that Aboriginal peoples had mined flint there.[7]
Koonalda Cave was declared as a prohibited area under the South Australian Aboriginal and Historic Relics Preservation Act 1965 on 30 May 1968.[8] It was listed on the South Australian Heritage Register on 4 March 1993 and inscribed onto the Australian National Heritage List on 15 October 2014.[9][10] It was also listed on the now-defunct Register of the National Estate.[11]
