In the surroundings there are plenty of memories from the last ice age and the period about 9500 years ago when the ice retreated from Bergslagen. Here the border between land and sea was located, which meant that many special natural formations arose right here. The red soil (which was previously the raw material in local iron production) is found in a large area with layers that vary from a few centimeters to a few meters. The red soil was formed when the inland ice melted. Iron was dissolved from the bedrock and followed out into the watercourses via the groundwater. When the iron came into contact with the air, the iron was precipitated into iron oxides that formed thick layers (which contain up to 40% iron). Remains of blast furnaces (from iron production) have been dated with the C 14 method to 700 years BC. Red soil is still being formed.
