Using Camera Raw (ACR - Lightroom Develop module) I added Contrast (+30), Clarity (+40), Vibrance (+30) and a black border.
The glacier guide might like a copy.
Thanks Terri and KmH. KmH, you did a good job bringing out details in the snow. I intentionally edited my version to keep the contours of the snow very subtle. In flat light, they're very difficult to make out in real life. It's a strange feeling having to stare hard at the ground 10' in front of you trying to figure out if what you're seeing is flat or sloping.
