Sometimes Norwegian authorities surprise us. For example, by putting up megalithic monuments along roads crossing the mountain backbone of Norway. Still no idea why they do this other than making a "window" into the landscape view??
85mm f/2.8 PC-Nikkor on a D2X, B+W 403 filter. Neither UV nor IR, but nice nevertheless. The "window" monument itself is > 2m tall and must weigh tons. One of the glaciers in Jotunheimen, Smørstabbreen, is seen through the forced viewpoint.
