Extreme Cold pages start with warmth, movement, visibility, travel delay, and the least experienced person. Clothing and gear matter, but they do not make closed terrain, unsafe heating, poor visibility, or a long cold delay acceptable.
Extreme Cold
Use this section when cold, wind, wet clothing, indoor heating, or winter travel could reduce the margin faster than expected. Start with warmth, ventilation, road status, fuel, medicines, children, older adults, and pets, then choose the page that matches the weak point. Carbon monoxide alarms, severe exposure symptoms, and official road or shelter instructions take priority.

Field notes
Use these to narrow the first page to open.
- Check wind, wet clothing, exposed skin, travel delay, and the least experienced person first.
- Stage warmth and return options before adding runs, distance, or highway miles.
- Use staff rules, patrol, posted signs, or road status as decision inputs, not background noise.
- Treating warm clothing as permission to ignore closed terrain, unsafe heating, or poor visibility.
- Waiting until children, older adults, or beginners are already chilled before shortening the day.
- Driving into cold weather without a delay plan, fuel margin, and medicine timing note.

Add warmth, shelter, dry layers, and a vehicle fallback before cold exposure escalates.
Can everyone keep moving safely and return warm?
Shorten the day, use patrol or staff rules, and keep children and older adults on the conservative plan.
Are confusion, numbness, injury, collision, carbon monoxide concern, or inability to warm up present?
Use emergency services, ski patrol, or local help instead of continuing.
