Gosse's Bluff, called Tnorala by the Western Arrernte.
Let us now travel 175 km west of Alice Springs, where we see 5 km-wide ring-shaped mountain range that stands 150 metres above the desert, representing the remnant central uplift of an eroded 22 km-wide complex crater. The scientific explanation is that this structure formed from a comet impact some 142.5±0.8 million years ago. Over that time, the land eroded down almost 2 km in thickness. What we see today as the mountain range is the result of differential erosion, meaning the shocked stone is denser and eroded less than the surrounding landscape.
