After a week with maximum temperatures always below freezing point I visited the »Wissengubel«, one of the well-known waterfalls in our area.

The large volumes of water did not build up icicles on top of the wall.
The single big icicle is a giant ice tube with running water inside.
And on the ground the water disappeared in a huge ice pyramid.
