Gardnos crater is 5 kilometres (3 mi) in diameter, and was created when a meteorite with an estimated diameter of 200 to 300 metres (660 to 980 ft) struck 500 million years ago. At first this site was believed to be a volcanic crater, but in 1990 two geologists, Johan
Naterstad and Johannes
186:
The original bedrock in the area was fractured and a powder of crushed rocks was forced into all the fractures. This is the origin of the peculiar rock in this area. It is possible to drive into the centre of the crater, which makes the
Gardnos crater one of the world's most accessible meteorite
