I came across this fine example of a non-standard Swiss fingerpost in June. It leads to a wooden footbridge overlooking the forest on the Gägger.
"The storm of the century", Lothar, almost completely destroyed the forest at the end of 1999. That part of the forest will now be left alone to develop entirely naturally (which can be followed from the footbridge).
