Gosses Bluff, Australia

The Gosses Bluff crater in the Northern Territory of Australia is of great importance to the Western Arrernte Aboriginal people, who call it Tnorala. According to their beliefs, a group of women was dancing across the Milky Way. One of them put her baby in a carrier, which fell over the edge of the dance floor, hitting Earth and creating Tnorala.

The crater, which is 24 kilometers (almost 15 miles) in diameter, is thought to be about 142 million years old.

Australia is second only to North America in number of known impact craters. However, this may only be because the North American craters are more heavily studied than their counterparts in Australia.
