Hi James ,yes it's from Clingmans Dome ,an Icon but you need a shot from there its a fantastic place.
I really like it from the parking lot better, vs all the way up the long walk to the top. From the parking lot around the back end is great for sunset if you climb up in the boulders[ if you are capable ].I wasn't when I was there, it's also a great place for night shots. If you would like some tips on where to go I can probably help. I spent 5 months working and photographing the area , it's well know for weddings also.
