This ice looks so strange, especially those two bulges, where one looks like is is rolling down the handrail. I cannot guess how this could happen, but it must has been frozen very fast ... or a slimy frost-demon was going upstairs and used the handrail ;)
I had not thought of the Slimy frost demon, that could well be it before you gave me this revelation,I thought it was water dripping down and freezing on eit hit the ice cold rail :)
Yes, but you said there was nothing dripping down, and those bulges are suspect - the upper one looks like slime that slips down the handrail and is frozen ... is must be a slimy frost demon :)))
