Cool! It's like one of those puzzles where you slide the squares around to make a picture. In this case, the finished picture would be the current arrangement of continents.

Thanks Dave.
Gosses Bluff is really nice, there's a high spot not far away so you can get a good look at it from up high. It's not far from Ayers Rock too, so well worth detouring to see it.
I have read that it's likely not a meteor as no meteor fragments have ever been found, Most likely an airburst of a comet, the circle of hills is the rebound pip in the centre of the crater, the actual crater is about 25Km across and only really visible from space photos.
The third photo on that page you linked is the Bungle Bungles a very interesting sandstone formation, the little creek in the photo cuts right into the sandstone massif in a semicircle, the result of another meteor impact shattering the sandstone, nothing left of a crater just this circular weak spot in the sandstone. The creek has cut a long deep narrow gorge, several Kilometres long and only a couple of metres wide, it's just magic.
