The hole in the ground for bodily waste when camping

Back in the early days of Israel, the Israelites were instructed (by God, via his earth servants) to do just that. It was quite a smart thing to do actually; a lot of the nations around them didn't and ended up sick because of it.

There is a book called "How to Shit in the Woods" that advocates smearing, burying, and/or bagging it out--depending on the terrain.

When camping, I prefer the tender caress of a clean rock or fir cone on my satisfied sphincter. None about? Leaves. In the desert at Burning Man? Hmmmm.

Most toilet paper will not break down the same way, that's why you don't put it in the hole.

In basic training they told us to carry a bag to put waste in that wouldn't break down naturaly. Also, leaving nothing behind but a covered-up hole with poop in it made it harder for the enemy to detect you were in the area.
