Wondering what to do when visiting an environmentally
sensitive area where human impact should be limited. Sure, packing out a little lunch garbage is one thing, we can all do that, but what about that delicate subject of ... your own body's waste.
For proper "burial" technique, including digging a proper hole, please read "How to shit in the woods", by Kathleen Meyer. A very popular and humorous (how could it not be) book for back-country toiletry etiquette, it has sold over a million copies. It has become a bit of a classic, perhaps to join the likes of "lip smackin, back-packin recipes", in fact, the two are sort of related.
When you are done learning the basics,
have a look at Chapter 4 on page 55 or so, "The Plight of the Solo Poop Packer", which also begins with the quote: "You cannot escape. Every day a part of your turns to shit". Words of wisdom indeed.
3 options that which I would like to mention from the book, the "J-UGH" (jug) which can be ordered from 800-642-JUGH, featuring aluminum construction to keep it from blasting to pieces under mounting gas pressure. Comes in Sojourner and Sprinter model, easy to clean, durable, and little wrappers to minimize the mess.
Secondly, there's the home-made "poop tube", made from 4" PVC tubing, with screw on lids. Certainly strong, and when used in conjunction with the type of brown paper bags used in kitty litter type scenarios, very easily dumped later.
Lastly, there is the "Tupperware" option, yes low cost, but frankly, this could lead to a popped seal. Kitty litter in any case, seems to be an ugly reality that you might want to look into for your container.
How humbling, you and the cat, at the same level. We however, are at the top of the food chain and there are no Park Wardens or other higher beings to rub our nose in our excrement when we drop our doo-doo in some pristine water or mountain top. So unlike a cat, it's up to you to police yourself. If you can can, look into specialized containers. I also seem to remember the combined method of the carry-along bucket kayaking in Baja, along with burning the paper with a wind-proof rock-cairn on land. Alas, many cairns of this size become a testament only to the favourite place to crap on a tiny Island.
Just remember, you are helping to keep an area pristine, and, your extra efforts are appreciated. Look at the mess Everest has become. And then there are the climbers on a rock-face, sort of no choice really, at least I would hope not. There are many groups out there already using these techniques, perhaps it's time you thought about this issue as well.
