I, like many here, spend a lot of time in the woods. Toilet facilities are not available. When the inevitable action is necessary, my best method is to locate a tree about 3" in diameter on a sloping hillside. Positioning myself on the downward side, I space my feet about 12" apart for stability, place toilet paper on right side, lower postierior about 18" above ground, make sure trousers are well out of the drop zone, make sure plumbing is aimed downward, and let nature occur. Then, holding onto tree tightly with left hand, reach down, pick up toilet paper with right, perform necessary cleaning act, then drop used item on top of previous deposit. Using both hands, pull toward tree and swing to side carefully maintaining balance. Pull up trousers, insure retention of wallet, keys, ect, then cover up deposit well with leaves and continue. Advice is to make sure tree will support weight prior to assuming position and not to use too steep a slope. Make sure feet are well planted. Works for me. Doing it out of a canoe is really a challenge.
