I would have to look at a map as I was not the driver but I am sure it is easy to find from Townsend, Tennessee.
I used a rather long lens to isolate the scene.
Our group found our way up to Clingman's Dome and had to jockey for a place to set up our tripods. We shot until well after sunrise then called it quits. The layer effect was difficult for me to achieve as one cannot over expose. The mountains just seem to keep going and going and the rising sun brings out such wonderful colors.
