Seljalandsfoss, Iceland. The size of some of these waterfalls are immense! This was during the Winter Solstice on 21 December 2016. We only had maybe 3 hours of direct sunlight that day. The winds were horrendous that day as well. The walking paths that go behind the waterfall was frozen over with what seemed like several inches of ice. I didn't have the proper footwear for walking on ice, so I played it safe. I don't have a banana for scale, but there's people on the bottom-right for scale.
