an then the fog disappeared

A few years ago we went to Værøy to visit family. We went for a walk to look at the view, but as we reached the top, the fog came in. And suddenly it left, as quickly as it arrived. I come from the northern part of Norway, which is known for it's fantastic scenery, but I have never seen anything like the mountains that surround Værøy and the region of Lofoten.
