Human waste - by the Accessfund

Select an inconspicuous site where other people will be unlikely to walk or camp – at least 200 feet (about 70 steps) away from water, trails, and camps. Dig a hole 6-8 inches deep and 4-6 inches in diameter. After doing your business, cover the cathole and disguise it with natural materials. If camping in the area for more than one night, or if camping with a large group, cathole sites should be widely dispersed. Use toilet paper sparingly and use only plain, white, non-perfumed brands. Better yet, use natural toilet paper like stones, vegetation, or snow.

Bag Systems – Desert environments, slot canyons, big walls, and forests environments

There are a number of readily available bag systems (or “wag bags”) on the market, including Restop, GO Anywhere, and Biffy Bag. The underlying principle of all of these systems is “pack it out.” Do your business, scoop it up in the bag, seal it and be on your way. All of these products do a good job of sealing off odor and can be disposed of in trash receptacles. Bag systems are generally the best option for sensitive environmental areas.
