I have gone through the answers of question When is it not OK to leave feces behind? It did answer a part of my question "I would really like to know how and where exactly do I select this area?" It also put an insight on "How far away from trail in wilderness should it be?"
I am new to hiking. So far I have been on about 15 different day hikes. I am planning to go on a multi-day hike soon. I would need to set up a toilet area in this case. I have read in posts and books that "toilet area" must be away from a water source, that "toilet area" must be lower than cooking area, etc. I am not exactly able to picture it as I haven't done it before. Which raised more questions
I would really like to know how and where exactly do I select this area?
What its size should be with respect to number of people who are going to use it?
How far should two toilet holes should be from each other?
How approximately far away from trail and the campsite should it be?
