Gosses Bluff, Northern Territory, Australia Target Name:   Earth Spacecraft:   Landsat 7 Produced by:   USGS Date Released:  14 August 2002 Related Document Terrestrial Impact Craters Download Options Name Type Width x Height Size gosses.jpg JPEG 1000 x 999 333K gosses.jpg JPEG 2000 x 1997 987K gosses.jpg JPEG 5461 x 5453 5M Location 23°50'S, 132°19'E Rim diameter 24 kilometers Age 142.5 +- 0.5 million years 142 million years ago, an asteroid or comet slammed into what is now the Missionary Plains in Australia's Northern Territory, forming a crater 24 kilometers in diameter and 5 kilometers deep. Today, like a bull's eye, the circular ring of hills that defines Gosses Bluff stands as a stark reminder of the event. The crater is located just south of MacDonnel Ranges (top of the picture). It is highly eroded. The circular ring of hills is actually (5 kilometers or 3 miles diameter) the results from differential erosion of the central uplift within this large complex crater. The crater rim is eroded to the point that it is no longer visible although is probably located along the grayish colored drainage system outside the inner ring.
