Mount Cook - Changing of the Guard

One of my favourite times of day is after the sun has set, and the first stars appear. They commonly call this the blue hour, but I like to think of it as the changing of the guard - the moment day becomes night. I was down on the South Island of New Zealand last weekend, and managed to witness this amazing moment as the sun went down to the west, and the after glow lit up the tops of New Zealand highest mountain, Mount Cook, and the lenticular clouds above.
