In the year 1746 Carl von Linné visited this place. He was told by the local farmers that on this mountain there were writhing in an unknown alphabet. Linné did know how to read runes but he could not read this writhing. It’s all a creation by nature, but looks human made, so it’s no wonder that the famous Linné was unable to read the “writhing”.
The local population in the 18th century said that the place of the writhing was once used to (black?) magic ceremonies. So be careful…
