This beautiful image is not mine, but was taken by Andreas Tille and was posted on Wikimedia Commons. I have read over the licensing information, and it appears that I’m free to use it (if not, I hope somebody tells me!). But I had been wondering how these horses survive the brutal winters in Iceland, and I think this explains it. Somebody had said their long manes keep them warm, but that couldn’t have been the total story!
