The Ritland crater is an impact crater located at the farm Ritland in Hjelmeland, Norway. It is about 2 km in diameter, and was created when a meteorite with an estimated diameter of 100 m struck 500-600 million years ago. The crater was later buried by sediments, of which it has been partly recovered. Source
