Saarijärvi is a 1.5 diameter impact structure mostly covered by a small lake by the same name. It is located about 40 km south from the town of Taivalkoski, Northern Ostrobothnia, Finland.
The structure's age has not been determined, but the oldest sediments from the drill-core are from Ediacaran period, i.e. about 600 Ma (million years) old.
