Thanks! I was really surprised when I looked out the window and suddenly could see Iceland so clearly. I understood that Hvannadalshnukur had to be down there somewhere. I'm not really sure what the dark line is, but I took the picture through the window and I don't think it was very clean. I guess it's just a scratch in the window. I have edited the photo in Photoshop to make it better, but the reflections or light to the left is hard to remove. I think you can see the Skaftafell campsite down to the left.
