If a Bear Charges You: Stand still, do not run. Stand your ground and use your bear spray. Spray when the bear is 60 feet (18 m) away or closer. If a bear charges, it may be a bluff charge.

If a Bear Makes Contact: Drop to the ground; play dead. Lie face down and clasp your hands over the back of your neck; stay still and silent. Wait several minutes after the bear leaves before getting up and leaving the area.
