Here is another image that was taken in extreme cold weather ( -13 F). The moisture rising above the river freezes on the surfaces of trees and bushes producing a frosted look to the flora. The sun was just coming up over the mountains to the left and the back lighting on the trees and bushes caused them to glow. The light on the river was being broken up by the fog and was producing very subtle colors of a rainbow. And although one cannot see it in the photo, quiet filled the place. All I could really hear was my own breathing, my heart beat in my ears, and the crunching on the snow when I moved my feet. Click on the image to see a large version.
