Using the Shadows/Highlights dialog I brightened the shadows around 5%, darkened highlights around 55%. Then I boosted saturation 12% for all colors. Removed noise from the sky, sharpened everything except for the sky, and finally I ran the burn tool across portions of the sky to make it more consistent. Sorry about the super blue mountains. I didn't see them until I posted the workshop photo! I hope you find that helpful to some extent.
