Good one! Though this is probably not what you had in mind, it's looking to me like some sort of alien energy gathering there in the distance, about to materialize.
@mcsiegle Thanks, Mary! I was thinking either Balrog escaped from the Mines of Moria - OR - an atomic explosion. Either way, pointless to run. Ha ha! :)
Unless you're doing the 365 project of course, because then you'll stop, figure out the best aperture and shutter speed, make the settings on the camera and stay there to get as many shots as you can...... ;-)
Great shot Julie
