Can you effectively navigate in snow-covered landscapes?

Reading Terrain Features

When navigating in snow-covered landscapes, reading terrain features is crucial. Look for changes in vegetation, such as tree lines or bare areas, which can indicate elevation changes or water sources. Also, note the direction of snowdrifts, which can indicate wind direction and speed. For example, in areas with strong winds, snowdrifts may be piled up on the downwind side of hills or ridges. Use these features to estimate your location and direction.

Natural Navigation Signposts

In snowy landscapes, natural navigation signposts such as cairns, rock outcroppings, or even animal tracks can be more visible than in other terrain. Cairns, for example, can be used as markers or landmarks, while rock outcroppings can provide a bearing or a reference point. Animal tracks can also indicate the direction of water or food sources. When following animal tracks, use the tracks of different species to estimate the time of day and the season.

GPS and Compass Techniques

When using GPS and compass in snowy landscapes, it’s essential to understand how these tools interact with the terrain. Use a compass to take bearings from prominent landmarks, and then use GPS to confirm your location and course. When taking bearings, use a technique called “triangulation,” where you take two bearings from two different landmarks and then use a chart or map to estimate your location. Additionally, use the “3-3-3 method” to estimate your location: take three bearings, three readings of your altitude, and three observations of your surroundings to get an accurate picture of your location.
