Quick Answer
Having a map and compass alongside your GPS for winter is essential for navigation and survival in extreme conditions. A map and compass can help you navigate when your GPS device fails or runs out of battery. This is crucial in cold weather situations where help may be delayed.
Using a Map and Compass in Winter
A map and compass are vital tools for winter navigation and survival. They provide a reliable means of finding your way when your GPS device fails or runs out of battery. When choosing a map, select one with a scale of 1:50,000 or 1:25,000 to ensure accurate route planning. Consider a map with a topographic overlay to help you identify potential hazards such as steep slopes and water bodies.
Compass Techniques for Winter Navigation
To use a compass effectively in winter, learn the following techniques: triangulation, pacing, and resection. Triangulation involves identifying two or more landmarks and using them to plot a course. Pacing involves measuring distance by counting your steps. To do this, divide 1 kilometer by 1,000 steps to estimate the distance. Lastly, resection involves using two or more known points to determine your position on the map.
Preparing Your Kit for Winter Navigation
When preparing your kit for winter navigation, ensure you have a waterproof map and compass case to protect them from the elements. Pack a backup battery for your GPS device and a portable power source such as a solar charger or hand-crank charger. Also, include a whistle, matches or a lighter, and a first aid kit in your winter kit to increase your chances of survival in case of an emergency.
