Peeing on Mount Rainier?

I'm doing a 8 day course on Rainier, the gear list says to bring a pee bottle for using in the tent. Where can I dump this out if we're supposed to pack out all waste? It will inevitably fill up and just be dead weight. Anyone with experience on this?

I seem to recall Bear Grylls having some advice on this topic.  If you don't find that approach to your liking however, generally piss is an exception to the "all waste" rule, and I would imagine your group would establish a designated place, a bit away from camp (and a bit away from where you get your snow to melt for drinking water).

This is a joke rigjt?

Don't eat the yellow snow.....

You don't pack out your pee. You're peeing in a bottle because it's too cold to go outside in the middle of the night, sometimes.

Your group will establish a "pee area" when you set up camp that's usually just a spot marked with a wand away from camp and away from any potential drinking water source. The bottle is if you wake up and have to pee at night but don't want to get out of the tent but honestly its easier to just put you boots on and go outside. If you really wanted to lug your pee around I guess you could always dump it out at Camp Muir or find a nice sized crevasse to dump it in? 

Protip: Bring a collapsible or square bottle to pee in at night while in the tent rather going outside. Why a collapsible or square bottle? Because most water bottles are round so in the dark you can grab the right bottle and pee. As for dumping it, as said there will probably be a group pee / poop spot. You dump it there.

Just kick some fresh snow over your pee puddle to no one else has to see it. The pee bottle is so that you don't have to get out of your tent when the night temps plummet to -35.

Two warnings about using a pee bottle:

1. Don't spill it in your tent or sleeping bag.
2. Don't mistake it for your drinking bottle.

Put a hefty ring of duct tape around your bottle so you can identify it easily.

Make sure the bottle has more than enough volume.

Be careful not to spill it with a collapsible bottle though. I'm a fan of the duct tape method (which you probably want to bring to repair stuff anyway) on a > 1L bottle

The most obnoxious person on the course gets to pull the sled containing a 55-gallon drum full of urine back down to Paradise at the end of the trip.

In all seriousness, I've done both the washout and funny-shaped bottle method. Bottled water containers are pretty good (very light, distinctive shape/texture) but make sure you get one with a wide enough mouth to accomplish your goal. Of course, that's different for every person.

And girth. 

Regarding putting duct tape on a bottle. One is better off putting the duct tape on one's water bottle as that bottle will be more accessible and used more often (especially for day trips).

And if you forget the bottle do not try this: http://publications.americanalpineclub.org/articles/13198907601/Inadequate-Equipment-for-Nocturnal-Diuresis-Weather-Washington-North-Cascades

“We hope the most important member of this trip has sufficiently recovered.”

An Ocean Spray bottle is big, lightweight, durable, and rectangular. 

Just to add on, if you pee in your tent and you're anywhere near muir or other somewhat densely populated camp don't just dump the pee out near your tent. People melt snow all over the place up there so generally try to dump pee/pee as off trail or out of camp as possible.

The bottle is def so you don't have to get out of the tent.

Honestly I think the idea is overkill for Rainier. You’re not going to be taking diuretic altitude medications or waiting out multi-day storms in your tent. If you get up to pee regularly at night at home maybe think about taking one.
