Understanding the Basics of Solar Navigation To begin, it’s essential to understand the basic principles of solar navigation. The sun rises in the east and sets in the west, which means it’s always roughly 180 degrees away from the direction of sunset. Knowing the approximate time of day also helps, as the sun’s position changes throughout the day. For example, at solar noon (the time when the sun is highest in the sky), the sun is due south in the Northern Hemisphere, and due north in the Southern Hemisphere.
Using the Shadow Stick Method One common technique for determining direction using the sun is the shadow stick method. To use this method, find a straight stick and stick it in the ground, then mark the end of its shadow with a small rock. Wait for some time, say 30 minutes or 1 hour, and mark the new end of the shadow. Draw a line between the two marks, and this line will be roughly south (in the Northern Hemisphere) or north (in the Southern Hemisphere). This method works because the sun’s position changes over time, causing the shadow to move in a predictable pattern.
Using the Sun’s Position to Determine Time Another crucial aspect of solar navigation is determining the time of day based on the sun’s position. In the Northern Hemisphere, the sun is due south at solar noon, and its shadow will be shortest at this time. By observing the sun’s position and the length of its shadow, individuals can estimate the time of day. For example, if the sun is high in the sky and its shadow is short, it’s likely to be around lunchtime (around 11 am or 12 pm). This skill is essential for planning and executing tasks, such as finding food, shelter, and water.
