Quick recognition
Solid white to cream-colored coat

Massive size
Adult males 900-1,500 lbs · stand 10 ft on hind legs. Largest land carnivore on Earth.
Long neck and small head
Distinct silhouette — longer neck-to-body ratio than brown bears, smaller ears, narrower head.
Black skin under white fur
Black nose and lips visible against white fur.
Tracks
Front paw print 12 inches wide — significantly larger than any brown bear.
Response protocol
- 1
1. Get to shelter
Any hard-sided vehicle or building. Polar bears can break tents and soft-sided trailers. Class A and Class C motorhome interiors are minimally protective; the rig's metal door is more secure than nothing.
- 2
2. Make noise — lots of it
Air horns, vehicle horns, banging metal. Polar bears can be deterred by loud sustained noise if they have not committed to predation.
- 3
3. Do not turn your back
Maintain visual on the bear at all times.
- 4
4. Fight if physically attacked
Strike the eyes and nose with rocks, sticks, or fists. Playing dead is fatal. Polar bears that attack are usually hunting.

5. Use any weapon available
Local Inupiat communities carry firearms in polar bear country — .375 H&H or .338 Win Mag minimum. Bear spray is a backup, not a primary defense.
Prevention
Travel with an armed local guide
RV travel north of the Brooks Range without a guide is irresponsible. Communities like Kaktovik have outfitters; budget accordingly.
Stay in established communities
Hard-sided buildings are the only reliable shelter. Wild camping outside designated campgrounds is not advisable.
Monitor U.S. Fish & Wildlife bear-incident reports
FWS issues seasonal alerts when bears are in town — Kaktovik especially has high traffic when sea ice retreats.
Lock all food and trash overnight
Polar bears are far stronger than brown bears. Use the community-provided bear-resistant cages, never a soft-sided cooler.
Avoid solo travel anywhere bears may be
Even short walks. Communities issue guidance based on seasonal bear movements.
Real case studies
2017 · Kaktovik, Alaska
A polar bear killed two researchers in the village. Both were outside hard-sided shelter at night. Their bear spray failed in -20°F wind conditions.
Lesson: Polar bear country requires firearms-level preparation. Bear spray alone is insufficient.
What authorities don't always tell you
Editorial secrets
Climate change is changing the encounter map
As sea ice retreats earlier and later in the year, polar bears spend more time on land hunting alternative prey. Communities like Kaktovik now see year-round bear presence where they used to see only seasonal traffic.
Inupiat communities have the deepest expertise — listen to them
Local communities have hunted and lived alongside polar bears for thousands of years. Local guidance — when bears are active, which areas to avoid, what's normal vs alarming behavior — is more accurate than any tourist guidebook.
Bear spray performance degrades in extreme cold
Below 32°F, canister pressure drops and spray range shortens. In -20°F arctic conditions, the spray cloud may dissipate before reaching the bear. Keep canisters inside your coat near body heat in winter conditions.

Frequently asked questions
Where in Alaska do polar bears live?
North Slope coastal areas — Utqiaġvik, Kaktovik, Wainwright, Nuiqsut. Also Bering and Chukchi Sea coastal regions. Not interior or southern Alaska.
Can I see polar bears safely?
Yes — Kaktovik operates a regulated polar-bear viewing season (typically September-October) with licensed guides. Never approach independently.
Are polar bears federally protected?
Yes — listed under the Marine Mammal Protection Act and the Endangered Species Act. Harassment is a federal crime.
Do I need a firearm to travel in polar bear country?
If you're a private RV traveler, hire an armed guide. Independent firearm carry without expertise is more dangerous than helpful.
