What should I do if the sun is blocked by clouds?

Natural Navigation Techniques

When the sun is blocked by clouds, it’s essential to rely on natural navigation techniques. One method is to observe the position of the sun’s shadow. In the northern hemisphere, the shadow of an object typically points north during the day, while in the southern hemisphere, it points south. To use this method, find a straight stick or object and mark its end with a small rock or piece of tape. Then, measure the length of the shadow and mark the end of it. Wait for about an hour and measure the new shadow length. The direction the shadow has moved is generally south in the northern hemisphere and north in the southern hemisphere.

Using the Stars for Navigation

Another way to navigate when the sun is blocked by clouds is to use the stars. The North Star, also known as Polaris, is located almost exactly in the northern direction in the northern hemisphere. In the southern hemisphere, the Southern Cross constellation is used for navigation. To locate the North Star, find the Big Dipper and extend the two stars at the end of the dipper’s “bowl” away from the dipper. These two stars will point towards the North Star. Use a compass to ensure you are pointing in the correct direction.

Additional Navigation Methods

If you don’t have a compass or are unable to use the sun’s shadow or star navigation, look for natural navigation aids such as landmarks, water sources, and prominent features like mountains or valleys. These features can help guide you in the right direction. Additionally, pay attention to the direction of animal tracks and bird flight patterns, as these can also indicate the direction of your surroundings. Remember to stay calm and use your common sense to make informed decisions about your navigation.
