Quick Answer
Following ridges in winter conditions can be a safer route due to their unique features that help navigate through whiteout, such as consistent elevation and less likelihood of water accumulation. This method reduces the reliance on GPS and contour lines, providing a more reliable means of navigation. The ridges' topography also offers better visibility.
Understanding Ridge Navigation
When navigating through snow-covered terrain in whiteout conditions, following ridges can be a lifesaver. The consistent elevation of ridges provides a clear reference point, making it easier to maintain direction. A ridge’s width typically ranges from 1-5 meters, offering a clear path to follow. To identify a ridge, look for a change in vegetation, soil color, or subtle variations in the landscape.
Using Contour Lines to Identify Ridges
Contour lines on a map can help identify and locate ridges. A ridge typically displays a series of high contour lines (every 10-20 meters) that converge and then diverge, indicating a change in elevation. By studying the contour lines, you can identify the top of the ridge and plan your route accordingly.
Navigating Whiteout Conditions with Ridges
In whiteout conditions, rely on the ridges to guide you through the terrain. Use your surroundings to estimate the direction of the ridge, and then adjust your course accordingly. Traverse down the slope of the ridge every 100-200 meters to maintain a clear view of your surroundings and to stay on course. This technique allows you to navigate through the whiteout while minimizing the risk of getting lost or disoriented.
