That's Jacob Peak on the right (foreground). Although close to Lady Mountain, the two are separated by a shallow saddle and about a pitch or two of 5.10-5.11 climbing on poor rock.
Also, what you're seeing left of center is just the cap of The East Temple. The mass below it is actually a separate mountain, Twin Brothers. Mountain of the Sun is just left of that. And Deertrap Mountain is on the far left.
Nice shot. I love Zion.
