That's St. Peter's Dome front and center! You should post this pic to my St. Peter's Dome page and I will put it on the main page.
...isn't that Mt. Vigil and San Luis Pk. on the horizon?? Can you actually even see St. Peters Dome from this location?
Nope, that is St. Peters Dome. Vigil and San Luis Peak are farther to the left (south) of this pic.
