Find East-West with the Shadow Stick Method
The shadow stick method is a fundamental wilderness navigation technique that leverages the sun's predictable movement to determine cardinal directions. By marking the tip of a shadow cast by a vertical stick at two different times, you can establish an east-west line. This line is formed because the sun always moves from east to west across the sky. Once east and west are known, north and south can be easily deduced, providing a reliable directional reference without a compass or electronic devices.

Key takeaways
- The shadow clearly moves from left to right (in Northern Hemisphere, facing the sun) over time.
- The second shadow mark is distinctly separate from the first.
- The stick remains vertical and stable throughout the observation.
- Avoid: Using an unlevel surface, which distorts shadow length and direction.
- Avoid: Not waiting long enough between marks, making the shift hard to discern.
- Avoid: Using a bent or non-vertical stick, which casts an inaccurate shadow.
Intended uses
- Navigation skill (Beginner, ~10 min practice)
- Requires: Straight stick (1-3 feet long), Small markers (stones, twigs)
Climate suitability
Any outdoor environment with direct sunlight; ideally open ground for clear shadow observation.

Required tools
- Straight stick (1-3 feet long)
- Small markers (stones, twigs)
Step-by-step
Find a level, open spot with direct sunlight and push a straight stick vertically into the ground.
Why: A vertical stick and level ground ensure an accurate shadow projection.
Mark the exact tip of the stick's shadow with a small stone, twig, or scratch in the dirt.
Why: This establishes your starting point for the sun's movement.
Wait 15-20 minutes for the stick's shadow to visibly shift and grow shorter.
Why: Sufficient time allows for a clear and measurable shift in the shadow's position.
Mark the new tip of the shadow with a second distinct marker.
Why: This provides the end point of the sun's apparent travel for your observation period.
Draw a straight line connecting your first mark (West) to your second mark (East).
Why: The first mark is always West, and the second mark is always East, directly indicating the E-W axis.
Tip: For greater accuracy, especially if observing for longer periods, consider drawing a circle around the base of your stick. The points where the shadow tip crosses the circle on either side will give you an even more precise east-west line.
Common mistakes
- Using an unlevel surface, which distorts shadow length and direction.
- Not waiting long enough between marks, making the shift hard to discern.
- Using a bent or non-vertical stick, which casts an inaccurate shadow.
- Performing the method too close to solar noon, when shadow movement is minimal.
Troubleshooting
- If the shadow moves very little, wait longer or repeat the process with a longer time interval.
- If marks are hard to see, use larger stones or scratch deeper lines.
- If the stick leans, re-set it firmly and vertically to ensure accuracy.
Field practice drill
Practice this method once a day for a week at different times, confirming the results with a compass. This builds observational skill.
Indicators of success
- The shadow clearly moves from left to right (in Northern Hemisphere, facing the sun) over time.
- The second shadow mark is distinctly separate from the first.
- The stick remains vertical and stable throughout the observation.
