What to do if you see a bear
If you are in a developed area (e.g. campground, parking lot, lodging area) or if a bear approaches you, act immediately to scare it away: make as much noise as possible by yelling very loudly (don't worry about waking people up if it's nighttime). If you are with other people, stand together to present a more intimidating figure, but do not surround the bear.
The intent is not to harm the bear, but to scare it from the area and restore its natural fear of people by providing a negative experience.
If you see a bear anywhere else, keep your distance (at least 50 yards, or about the distance four shuttle buses parked end to end would take up). If you get closer, you will be helping the bear become used to being around people.
Bears that become comfortable around people lose their natural fear of us and sometimes become too aggressive; sometimes they then have to be killed.
When a ranger sees a bear, the ranger may use non-lethal aversive tactics to chase the bear out of a developed area. During your stay, you may see and hear rangers patrolling public areas. You may hear rangers yelling at and chasing bears. The intent is not to harm the bear, but to scare it from the area and restore its natural fear of people by providing a negative experience.
What to do if a bear charges you.
Look big, raise your arms, and stand your ground. If the bear backs away, you should back away as well because the bear may be guarding food or cubs and view you as a threat.
If the bear makes bodily contact, you should tuck into a ball face down with your hands over your neck. In very rare instances, black bears have made predatory attacks on humans. If that ever happened, you would need to fight back.
What must be stored?
All food and anything with a scent (even if you don't consider it food). This includes garbage, recyclables, soap, shampoo, toothpaste, sunscreen, first-aid kits, baby wipes, lotion, hairspray, scented tissue, air freshener, pet food, insect repellent, tobacco products, baby car-seats, and window cleaner. Bears recognize ice chests, cans, bottles, and grocery bags so store them also.
How to Store Items Properly
In Picnic Areas
Store all food and related supplies properly, including ice chests. Never leave food unattended. Dispose of all garbage properly.
In all campgrounds, store all food and related supplies in the metal storage boxes. Only when camping where there are no metal boxes, store food and related supplies out of sight inside a vehicle. Never leave camp unattended if food is not stored. Store food day and night. Take infant car seats out of vehicles when parked overnight. Bears may enter campsites during the day, even if people are there. Keep a clean camp. Put trash in bear-resistant cans and dumpsters regularly.
Properly store all food and related supplies left at the trailhead, including ice chests. Don't leave your backpack and walk off to take a photograph. Bears know packs are a source of food.
Bears & Food Storage While Backpacking
You are required by federal regulations to store all your "food" properly throughout Devils Postpile National Monument. You must have your food stored unless it's within arm's reach (so, don't go for a swim or take a nap while leaving food out).

Bear-Resistant Food Canisters
Bear canisters are hard-sided portable containers intended to fit within a backpack and capable of storing several days’ worth of food. You may use any allowed canisters.
Food lockers ("bear boxes") are only available at designated campsites in the Valley and at the trailheads. You are encouraged to carry canisters even when hiking in areas where bear boxes are available because they may be unavailable or full in these busy areas. Canisters increase your freedom in selecting campsites away from developed or highly used areas. Food lockers are communal: personal locks are not allowed and will be removed.
NOTE: These regulations and precautions help decrease the chance of personal injury or property damage. However, bear damage and confrontations are still possible even when all of the above guidelines are followed. Failure to comply with these regulations may result in citation and/or impoundment of property.
