It could have been Norwegian Hills and Valleys, but we are now approaching Værnes Airport, Trondheim.
This could have been snow clad hills and valleys ("Norske fjell og dalar") but it isn’t. I was on a quick trip to Trondheim recently and had a nice view out above the skies. As you probably can guess, the sun was not shining in Trondheim. Actually the snow was covering the hills below the skies as well, but I didn’t get any pictures.
