Navigation & Whiteout
Snow erases trails, cold kills batteries, and fog erases the horizon. Winter navigation means trusting the tools that don't need a charge.
Compass-First Travel
GPS is a convenience in winter; the compass is the plan. Batteries and screens fail at exactly the temperatures you're navigating in.
- Take a bearing at every decision point (trail junctions, creek crossings) before conditions close in.
- Note back-bearings: if visibility drops, you can always retrace your exact line.
- Snow buries trail blazes and cairns — navigate by terrain and handrails (ridges, creeks, shorelines), not trail furniture.
- A watch, altimeter, or pace count cross-checks your position without any battery.
Maps and GPS as Backup
Electronics still earn their place — as long as they're treated as the second system.
- Download offline maps before you lose signal, and carry paper maps in a waterproof case.
- Keep the phone and GPS warm: inside pocket, airplane mode, warmed batteries.
- Lakes and frozen rivers look like easy highways but drift and change — treat them as shortcuts, not routes.
- White terrain hides distance: features arrive slower than they look, so trust bearings over feel.
Whiteout Protocol
In a whiteout, snow surface and sky merge into one flat white — depth perception and horizon vanish completely. People walk in circles within minutes.
- The moment visibility collapses, stop. Whiteouts rarely improve by pushing deeper into them.
- If you must move: rope or link the group, follow a compass bearing exactly, and count paces.
- Shelter immediately if wind is building — a dug-in hour in a storm beats an exposed hour lost.
- Mark your stopping point so rescuers (or you) can find it when visibility returns.
Do
- Stay calm and make the group sit down, insulate from the snow, and wait it out.
Don't
- Never guess a direction in a whiteout — guessed headings are how groups get separated.
Whiteouts and disorientation
If your GPS says you're stationary but your legs say you're walking, stop immediately — that sensation is the classic whiteout trap and it precedes most winter navigation fatalities. Anchor to a fixed point and re-establish a bearing before moving.
