Acraman crater
Acraman crater is a deeply eroded impact crater in the Gawler Ranges of South Australia.
It is marked by Lake Acraman, a circular ephemeral dry lake about 20 kilometres (12 mi) in diameter. The crater and the later discovery of its ejecta were reported in the journal Science in 1986.[1][2] The evidence for impact includes the presence of shatter cones and shocked quartz in shattered bedrock on islands in Lake Acraman.
