I normally don't share old crap from 7 years ago, but the Darby Ice Cave was one of the craziest things I've done. We entered a cave on one side of the Teton's and 8 hours later we exit out a different cave on the other side of the mountain. In between we climbed, rappeled, squeezed, waded across an huge and ice cold underground lake, followed an ice flow that turned into an underground river and lived to tell the tale. It was a blast but the pucker factor was massive.

Here's a short video of our trip.
