How to Determine True North: 14 Steps
Introduction
Finding true north is essential whether you’re an avid hiker, a casual explorer, or just trying to improve your navigational skills. True north refers to the exact direction of the North Pole, which is different from magnetic north, the direction in which a compass points. Magnetic declination—the difference between the two—is important to consider when navigating with a compass. In this article, we’ll guide you through 14 steps to help you determine true north without using any specialized equipment.
1. Find a Clear Observation Point
To start, find an open area with a clear view of the sky. It’s crucial that you can see both the horizon and the stars for this process.
2. Identify Polaris (the North Star)
Search for the Little Dipper and Big Dipper constellations in the night sky. They lead you to Polaris which remains fixed in relation to Earth’s rotation and is directly above true north.
3. Observe Preceding Stars
In addition to Polaris, pay attention to Cassiopeia and other constellations close to it. Familiarize yourself with their position relative to Polaris so that you can locate it more easily.
4. Time Your Observations
Time your observations near dusk or dawn when both terrestrial landmarks and stars are visible. This will help ensure accurate alignment when sighting true north.
5. Align Yourself with True North
Using Polaris as your reference point, align yourself so that it’s directly in front of you at eye level. This alignment will indicate true north.
6. Mark Your Position
Place an improvised marker such as a stick on the ground at your feet to mark your position.
7. Wait 30 Minutes
For a more accurate reading, wait for half an hour before making your next observation as stars move slightly over time.
8. Observe Polaris’ Movement
After 30 minutes, check whether Polaris has moved to the left or right of your marker. Adjust your position accordingly.
9. Create a True North Line
By repeating steps 6 to 8, you can create a straight line on the ground that points toward true north.
10. Use the Sun’s Shadow
During the day, use a shadow stick to track the sun’s position. As it moves from east to west, the tip of the shadow will trace a generally east-west line, allowing you to figure out true north and south.
11. Find the Equator
Identify your general latitude based on visible constellations. Knowing whether you’re in the Northern or Southern Hemisphere provides additional context for determining true north.
12. Utilize Analog Watches
With an analog watch, point the hour hand toward the sun. Bisecting the angle between the hour hand and twelve o’clock will give you a north-south line which can help you determine true north.
13. Apply Magnetic Declination
Account for magnetic declination by making necessary adjustments when using a compass. These adjustments vary by location and time so make sure to have updated information.
14. Practice Your Skills
The more experience you have with observing stars and their positions, the better your navigational skills will become at finding true north without any tools or aids.
Conclusion
By following these steps, you can successfully determine true north without relying on modern devices. However, always bring reliable navigation tools like GPS and maps as backups to ensure safety during outdoor activities and travels.
