If you have a deterrent such as bear spray or a firearm, use it as a last resort if the bear charges and appears intent on contact. An attack is when a bear physically contacts you. Lay on your stomach with your legs spread slightly apart. Lock your fingers behind your head. This position will protect your face and neck.
Bears often focus defensive attacks on a person's face if unprotected.
If the bear flips you over, continue rolling until once again your stomach and vital organs are protected against the ground. If you've kept your pack on it may provide some protection for your back and neck. Do not struggle or cry out. Typically, a defensive bear will stop attacking once it thinks you are no longer a threat. When the attack stops, remain still.
