Quick Answer
In a whiteout, the best contingency plan is to stop navigating and wait for visibility to return, using a compass to determine the direction of travel and any landmarks as references. Utilize a fixed point or recognizable feature to anchor your position. Employ a "dead reckoning" method to estimate distance traveled.
Whiteout Navigation Strategies
In extreme whiteout conditions, prioritize survival over navigation. Avoid traveling unless absolutely necessary, as disorientation and exhaustion can set in quickly. If you must navigate, stick to a compass bearing and use landmarks as references. For example, a large tree or a body of water can serve as a fixed point to anchor your position.
Utilizing Dead Reckoning
Dead reckoning involves tracking your movement using a combination of speed, direction, and time. To do this effectively in a whiteout, estimate your speed (typically 2-3 miles per hour) and multiply it by the time traveled to estimate distance. For instance, if you’ve been walking for 30 minutes at a moderate pace, you’ve likely traveled about 1-1.5 miles. Use your compass to determine the direction of travel and update your position accordingly.
Preparing for Whiteout Navigation
Before embarking on a journey in potentially whiteout conditions, prepare by packing essential items such as a compass, a map, and a GPS device. Wear protective gear, including goggles and a face mask, to shield yourself from wind and snow. Consider carrying a whistle or other signaling device to alert others in case of emergency. Stay aware of weather forecasts and adjust your itinerary accordingly.
