Do you mean Node: Knoten: 2975387975, (Standort: 46,5705015, 7,9692677) where the path to the Guggihütten crosses the Trümmelbach?
I walked the trail a few years ago and it was actually very difficult to cross the creek then too.
Since it is the normal path to the Guggihütte, I have inserted a ford. Possibly the conditions have become more difficult - possibly it also depends on the temperatures (meltwater).
