Burn out tin cans and scraps after a meal, or use dried foods. It is best not to wipe your hands on clothes while cooking, and to avoid cooking near your tent. In a campground, use garbage disposal facilities. In the backcountry, hikers are required to pack out all garbage. Do not bury garbage.
Bears can easily smell it out and dig it up.
Do not pitch your camp where you find fresh tracks or droppings or along a trail clearly used by animals. Be particularly careful in high winds, when an animal may not be able to pick up your scent soon enough to avoid you. Female bears with cubs are especially dangerous. Never approach a cub, even if it seems to be alone, and never get between a cub and its mother. Evidence indicates that bears are likely to be more aggressive toward those wearing scented cosmetics, hair spray, or deodorant, and women in menstruation.
