Gardnos crater is a meteorite impact crater in Nesbyen municipality in Buskerud, Norway. It is located inside Meteorite Park at Gardnos 10 kilometres north of the town of Nesbyen.
Gardnos crater is 5 kilometres in diameter, and was created when a meteorite with an estimated diameter of 200 to 300 metres 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 A. Dons, confirmed that it was in fact formed by meteorite impact.
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.
