The view of the Belton Hills, from across Lake McDonald near Fish Creek in Glacier National Park, was completely obscured by clouds and fog when I arrived, earlier in the morning. I waited for the highest peaks to appear so that their reflection would be cast on the surface of the lake. Fortunately some of the fog and clouds remained which added a bit of mystery. I chose not to use a longer exposure, which would have resulted in a smooth reflection, but it would have rendered the atmospherics without any detail.
