Karijoki (Swedish: Bötom) is a municipality in Southern Ostrobothnia in Finland, located 25 km from the coast and 90 km south-west of Seinäjoki. With only around 1,500 inhabitants it is a small place, but it gained fame when a Neanderthal cave (called the Wolf Cave) was discovered in 1997.
Karijoki is 14 km inland from the Lålby crossroads of E8 (national road 8) in Kristinestad. From the east the road (663) comes in from Kauhajoki. There is also a road from Teuva in the north and from Isojoki in the south.
The cave was formed as a result of erosion and it is estimated to be more than 2.6 million years old. In the interglacial period, between ice ages, it was filled with sediment layers that remained untouched unlike the rest of the area. The cave is 116.5 meters above today’s sea level. The ceiling of the cave is quite low; the highest spot is 2.2 meters high and the entrance is only a little bit over a meter high. The size of the cave is not precisely determined because it is still partially filled with sediment layers but it is estimated to be over 400 m2. It is very exciting to stare at inside and give place to the imagination, travel back 100,000 years ago. It is possible to get an idea of the size of the cave at the opening but safety precautions prevent visitors from entering the cave.
In 1998 the archeological excavations were started. The drilling was stopped in 2000 when temperature changes created a danger of the cave collapsing. The ceiling of the cave was reinforced, allowing the work to continue again. Although, because it’s such a vulnerable spot the investigators preferred to postpone the excavation until the research systems improve so nothing precious would be ruined. Expertise from different fields participate in the enduring investigation, among the participants are the Geological Survey of Finland, the National Board of Antiquities, and the University of Helsinki’s Dating Laboratory.
As mentioned before, inside the cave were found traces of human life from over 120,000 years ago, before the Ice Age covered the land for the next thousands of years. There was found burnt rock which gave certain evidence that fire was burned there, also many diverse stone tools. The techniques used to make these artifacts were the classic techniques used by Neanderthal to shape rocks which research dates back 130,000–115,000 years ago. Therefore, it is basically a fact that the Neanderthal inhabited this cave.
This is a unique attraction, there is nothing like it anywhere else in the Nordic countries. The terrain around the Wolf Cave is abundant with signs of the Ice Age and the cave itself is the oldest known human dwelling in Finland. The study of the Wolf Cave is an enduring task and rewriting the history of habitation in the Nordic countries.
