Hmm, my wife went to Geneva over the summer on business and tourned an ice cave in a glacier. She just had a lousy point-and-shoot camera at the time, though, so dunno if she got any decent pics. I'll check though.
I searched my archives and this is the closest I found. This was taken behind a wall of ice while climbing about 20 years ago. Sure could have used a digital cam back then, I would have taken more pics.
