This is a three shot pano that I took while in Yellowstone last year.  As I recall, the weather was overcast, and it was getting to be later in the afternoon on to evening.  This, IMO, is a morning shot, and the next time I go out there, I plan on trying to be there very early - though not necessarilly sunrise.  
Anyway, all the panos here gave me the urge to dig through the back catalog to see what I had.
