What are best practices for using shadows on uneven terrain?

Understanding Shadow Length and Direction

Use the length of shadows to estimate the time of day. In warm climates, the sun is high in the sky during the middle of the day, and shadows are typically short. As the sun approaches the horizon, shadows grow longer. Knowing the length of shadows can help you estimate the time of day and plan accordingly. For example, if the sun is high in the sky and shadows are short, it’s usually around 10 am to 2 pm.

Using Reference Points for Direction

Look for reference points such as ridges, valleys, or landmarks to help you estimate direction. Use the sun’s position to determine which way is north. In the northern hemisphere, the sun rises in the east and sets in the west. If you’re in a valley, look for a ridge or a mountain peak to use as a reference point. This will help you determine which direction is north and plan your route accordingly.

Measuring Angles and Distances

Use a stick or a rock to measure angles and distances. Draw a line in the dirt or on a rock to mark the direction you’re heading. Use a stick to measure the angle of the sun and estimate the direction you need to go. This technique is especially useful when navigating through dense forests or in areas with limited visibility. By combining these techniques, you can use shadows to navigate uneven terrain with accuracy and confidence.
