Looks like the Wilson Cliffs just outside Las Vegas in the Red Rocks area.
I didn't know that what why they were called, Rajan, but you've got the location.
Slobodan, I'm not sure what you're looking at. There shouldn't be barrel distortion, as the 24-105 was at 88mm and I had the LR lens correct enabled which I would hope would have caught anything remaining.
