Mound the mineral soil over the bag, the mound should be 6 to 8 inches thick. The thickness of the mound is critical as it insulates the bag and ground surface. The circumference of the mound should be larger than your intended fire to plan for the inevitable spreading of coals. Construct your fire with downed wood less than 1.5 inches in diameter. Keep the fire small.
Wildlife have their own daily patterns and are instinctively afraid of humans.
Our presence disrupts their patterns and may affect their health. Before contact with humans wildlife are fully capable of foraging their own food and fending for themselves. When wildlife see humans as a source of food they lose their fear of humans and become habituated. Habituated predators become problem animals and are often shot, or at best relocated. Leave the wildness in wildlife and don't contribute to habituation through poor wilderness practices.
