Wolf Cave

Susiluola (Swedish: Varggrottan, Wolf Cave') is a crack in the Pyhävuori mountain (Swedish: Bötombergen) at the border of Kristinestad and Karijoki municipalities in Finland. The upper part of the crack forms a cave that was until recently packed with soil. In 1996, some objects were found here that brought about speculations that it could have been inhabited in the Paleolithic, between 120,000 and 130,000 years ago. These objects, if authentic, would be the only known Neanderthal artifacts in the Nordic countries.
