Traveling across the Denali Hwy late in the fall when most sane folks would be by the fire, garnished an incredible gallery of images. This particular image was taken at the MacClaren River looking north towards the Alaskan Range. While the air was dead calm where I was standing, obviously the wind was blowing over the range which created the lenticular clouds floating over their tops. Photo captured D1H, 80-400VR on Lexar digital film.
