The day these were taken began with heavy fog and mist that lifted, shifted and settled back in again several times during the day. The mountains and even the sea would be fully shrouded for a while, and then the fog would gradually lift revealing perhaps just the ice scattered on the sea, or perhaps a mountainside and glacier before closing in again.
