Kummakivi
Natural landmark in Finland
From Wikipedia, the free encyclopedia
Kummakivi (lit. 'odd stone' or 'strange stone')[1] is a large balancing rock in Ruokolahti, Finland. The 7-metre-long (23 ft) boulder is a glacial erratic that lies on a convex bedrock surface with such a small footprint that it almost appears to be moving,[2] but so firmly that it cannot be rocked with human force.[3][4][5]


The boulder is located in a forest in the western part of the Ruokolahti municipality, near the border of Puumala.[6][7]
