Quick Answer
To determine direction using a stick and shadow, find a straight stick and mark the end of the shadow with a small rock. Wait for 15-20 minutes and mark the new end of the shadow with another rock. The midpoint between the two marks will be south.
Understanding the Basics
To use a stick to tell direction, you need to understand that the shadow of the stick will change direction over time due to the movement of the sun. The sun moves from east to west, and the shadow of the stick will move in the opposite direction, from west to east.
Measuring Shadow Length
To determine the direction, you need to measure the length of the shadow. Find a straight stick and place it in the ground. Mark the end of the shadow with a small rock. Wait for 15-20 minutes, and mark the new end of the shadow with another rock. The longer the shadow, the closer to noon it is. If the shadow is short, it’s early morning or late afternoon.
Calculating the Direction
The midpoint between the two marks will be south. This method is based on the fact that the sun is directly overhead at noon, and the shadow will be shortest at this time. By measuring the shadow length and calculating the midpoint, you can determine the direction of south, which can be used as a reference point to navigate.
