Biggest, if we look overall, waterfall of Sweden - Tannforsen. Here in its winter look. After really cold days, waterfall begins to freeze, first - building this huge icycle forms on the sides, later, at the end of February - March, is covered by ice in almost whole size! - just imagine the mass of ice which gather around the flowing water... waterfall is 60 meters wide.
Looking at your pic just reminds me of what's to come pretty soon - snow, lots of it:)
Great that we live in countries where we can experience snow... just imagine how emty the winter would be without it...
