This dude took on Mt Everest.. read the interview at The Cacophony Ensemble

C: And bowel movements on the mountain?!

MD: Well, at Base Camp it's reasonably civil. There's a small tent. It's smells feral but it's warm...and on Everest, anything warm is pretty good. Once you're getting further up the mountain it becomes a little trickier. You don't want to expose anything for too long (and at some temperatures it's not all that easy to locate through 6 inches of insulation). Exposure is a serious problem. We use a pee-bottle at night and for the weightier offerings zip-lock bags come in handy—these get jettisoned on the mountain the next day. Our climbing gear has easy access backsuits so it's not too hard although a few climbers have been known to make deposits in their hoods in error.
