Pick up litter and pack it out. Packing out all unburnable material including garbage will leave your campsite and trails ready for the next backcountry user. Pack out or completely burn any food scraps. Allow wild animals to eat their natural diet. Choose bathroom break locations wisely.
Improper sanitation can contaminate streams and lakes.
Make your toilet well away from camp and at least 100 feet away from any standing or running water. Dig a shallow trench and cover after use. Dispose of waste or wash water at least 100 feet away from any water source. Although the clear, cold water of streams is very tempting, it should be boiled or disinfected before it is consumed. Even the clearest stream may cause illness.
