Cmac, correct assumption. Basically the view is of the Superstition Wilderness (thats Weavers Needle really small on the middle right horizon) as seen from the Four Peaks Wilderness outside of Phoenix, AZ USA.
I'm gonna guess somewhere near the superstitions, but I saw a very similar view up from the cave creek area. It was completely overcast and in the morning though. Love the light you got here, as always.
