Several hundred years ago, an underground spring washed out the gypsum-rich soil of a small forest to such an extent that the entire forest disappeared into a deep hole. Today's Blauseeli emerged from this hole. Even today, the tree trunks of the former forest can be seen at the bottom of the mountain lake.
