The Rocking Stone of Onkiniemi, Sysmä

Onkiniemi Rocking Stone is located in Sysmä. This massive boulder, transported here by the ice age glaziers, has become lodged precariously on the flat rocks, as if it could at any moment roll down onto the adjacent E 75 road.

Marked in the Prehistoric Artefacts Register as the Onkiniemi “rocking rock”, the boulder is now a protected natural site. Its name comes from the fact that before it really was possible to move it slightly by pushing. It is no longer possible, however, to move the stone with muscle power alone because, as the story goes, somebody tried at the end of the 1960s to use a jack to roll the boulder down onto the road. It is suspected that the guilty party was a frustrated motorist. The massive boulder has since been fixed to the cliff.
