Ålstensgrytet/Erratic

A very large erratic in Ålstensgrytet. The erratic block is about nine meters high and one of the Stockholm area's largest. This mighty erratic, called Alastenen (or Ålstenen) is located along the promenade. Traces of inland ice. The top of the nine-metre-high moving block is crowned by an old iron cross, which the companion erected in 1793. Wikipedia
