Quick Answer
Use sun shadows to estimate direction and track movement in the woods by observing the angle and length of shadows, and adjust your route accordingly, ideally every hour to account for the sun's movement.
Understanding Sun Shadows
When lost in the woods, using sun shadows can be a simple yet effective method for directional finding. The key is to observe the angle and length of the shadows, which will help you determine the direction of the sun. Keep in mind that the sun is approximately 93 million miles away, but its rays are so precise that the sun’s apparent position in the sky can be used to estimate direction.
Estimating Direction with Shadows
To use sun shadows for directional finding, follow these steps:
- Observe the length of the shadow of an object, such as a tree or a rock.
- Compare the length of the shadow to your own height.
- If the shadow is equal to your height, the sun is directly overhead (at the equator).
- If the shadow is shorter than your height, the sun is higher in the sky.
- If the shadow is longer than your height, the sun is lower in the sky.
Adjusting Your Route
Adjust your route every hour to account for the sun’s movement. In the northern hemisphere, the sun appears to move from east to west, and in the southern hemisphere, it moves from west to east. By observing the sun’s position and adjusting your route accordingly, you can use sun shadows to help you stay on course.
