Methods for Creating a Natural Compass
Several methods can be employed to create a natural compass, each utilizing readily available resources and simple principles. Here are some of the most effective techniques:
1. The Magnetized Needle Method
This is perhaps the most well-known and reliable method for creating a natural compass. It requires a small piece of ferrous metal (such as a needle, pin, or paperclip), a magnet (if available, but can also be created through friction), water, and a leaf or small piece of wood.
Materials Needed:
- A small piece of ferrous metal (needle, pin, paperclip)
- A magnet (optional, but enhances magnetization)
- Water (in a shallow container)
- A leaf or small piece of wood
Instructions:
- Magnetize the Needle: If you have a magnet, stroke the needle in one direction only, from the eye to the point, about 50 times. This aligns the magnetic domains within the metal, turning it into a temporary magnet. If a magnet isn't available, you can magnetize the needle by rubbing it vigorously against a piece of silk or even your hair. The key is to stroke in a single direction.
- Float the Needle: Carefully place the magnetized needle on the leaf or small piece of wood. The leaf should be small enough to float freely in the water without touching the sides of the container.
- Observe the Alignment: Gently place the leaf with the needle on the surface of the water. Ensure the water is still and free from disturbances. After a few moments, the needle will align itself approximately with the Earth’s magnetic field, pointing towards magnetic north.
- Determine North: Once the needle has stabilized, observe its orientation. Remember that the magnetized end will point towards magnetic north. Keep in mind that magnetic north differs slightly from true north, a phenomenon known as magnetic declination. This difference varies depending on your location. For precise navigation, consult a declination map or online resource to adjust your bearings accordingly.
Example:
Imagine you are trekking in the Canadian Rockies and become separated from your group. You have a sewing kit with a needle and a pocketknife with a small magnetized component. Using the pocketknife to magnetize the needle, you then float it on a small leaf in a puddle. The needle aligns, allowing you to determine north and head towards the known direction of the trail.
2. The Sun Compass Method
The sun compass relies on the sun’s apparent movement across the sky to determine direction. This method is particularly useful in open areas where the sun is visible throughout the day. It’s crucial to understand that the sun rises in the east and sets in the west, but its exact position varies depending on the time of year and your latitude. This method works best around the equinoxes (March and September) when the sun's path is closest to true east and west.
Materials Needed:
- A stick or straight object
- A flat, level surface (ground or rock)
Instructions:
- Place the Stick: Insert the stick vertically into the ground or on a flat surface. Ensure it is firmly in place to prevent it from moving.
- Mark the Shadow Tip: Mark the tip of the shadow cast by the stick with a small stone or another marker.
- Wait 15-30 Minutes: Wait for a period of 15 to 30 minutes. The shadow tip will move as the sun appears to move across the sky.
- Mark the New Shadow Tip: Mark the new position of the shadow tip with another stone or marker.
- Draw a Line: Draw a line on the ground connecting the two shadow tip markers. This line represents the east-west axis. The first marker (initial shadow tip) indicates west, and the second marker indicates east.
- Determine North and South: Stand facing the east marker (the second shadow tip). North will be to your left, and south will be to your right.
Considerations:
- Time of Day: This method is most accurate near sunrise and sunset when the shadow is longer and easier to measure.
- Accuracy: The accuracy of the sun compass decreases as you move closer to midday because the shadow becomes shorter and less defined.
- Latitude: The sun’s path varies with latitude, so adjust your interpretation accordingly. In the Northern Hemisphere, the sun is generally to the south, while in the Southern Hemisphere, it is generally to the north.
Example:
You're lost in the Sahara Desert. You plant a stick in the sand and mark the shadow's tip. After 20 minutes, you mark the new tip. Connecting the points gives you the east-west line. Knowing that water sources are typically north of your location, you use this information to orient yourself and begin walking north.
3. The Shadow-Tip Method (Advanced)
This is a more advanced method that provides a more accurate determination of north-south orientation using the sun's shadow. It involves marking the shadow tip at different times of the day and using these points to draw an arc.
Materials Needed:
- A stick or straight object
- A flat, level surface (ground or rock)
- A string or cord
- Two markers (stones or sticks)
Instructions:
- Place the Stick: Insert the stick vertically into the ground or on a flat surface. Ensure it is firmly in place.
- Mark the First Shadow Tip: Mark the tip of the shadow cast by the stick in the morning (e.g., around 9 AM).
- Draw an Arc: Using a string or cord, create a radius equal to the distance from the base of the stick to the first shadow tip. Draw an arc on the ground with the base of the stick as the center.
- Mark the Second Shadow Tip: Continue observing the shadow throughout the day. When the tip of the shadow touches the arc again in the afternoon (e.g., around 3 PM), mark this point.
- Draw a Line: Draw a line connecting the two shadow tip markers.
- Find the Midpoint: Find the midpoint of the line you just drew.
- Draw a Line to the Base of the Stick: Draw a line from the midpoint to the base of the stick. This line represents the north-south axis. The end of the line closer to the first shadow tip indicates north, and the opposite end indicates south.
Considerations:
- Accuracy: This method is more accurate than the simple sun compass method because it accounts for the sun’s changing angle throughout the day.
- Time Required: This method requires several hours to complete, as you need to wait for the shadow to touch the arc a second time.
- Sunlight: This method requires a clear, sunny day for accurate results.
Example:
Stranded on a remote island in the Pacific, you use a sturdy branch as your vertical stick. Marking the shadow tips in the morning and afternoon, you draw the arc and connect the points. The midpoint line accurately shows you the north-south direction, helping you locate a potential freshwater source that you know is located to the north.
4. Using the Stars (Night Navigation)
In the Northern Hemisphere, the North Star (Polaris) is a reliable indicator of north. Polaris is located very close to the celestial north pole, making it a fixed point in the night sky. To find Polaris, you first need to locate the Big Dipper (also known as Ursa Major). Extend an imaginary line from the two stars that form the end of the “cup” of the Big Dipper. This line will point directly to Polaris.
In the Southern Hemisphere, finding south using the stars is more challenging, as there is no bright star directly aligned with the south celestial pole. However, you can use the Southern Cross (Crux) constellation. Extend the long axis of the Southern Cross by about 4.5 times its length. This point will be close to the south celestial pole.
Materials Needed:
- Clear night sky
- Knowledge of constellations (Big Dipper, Southern Cross)
Instructions (Northern Hemisphere):
- Locate the Big Dipper: Find the Big Dipper constellation in the northern sky.
- Extend the Line: Draw an imaginary line from the two stars at the end of the “cup” of the Big Dipper.
- Find Polaris: This line will lead you to Polaris, the North Star.
- Determine North: Polaris is directly above north.
Instructions (Southern Hemisphere):
- Locate the Southern Cross: Find the Southern Cross constellation in the southern sky.
- Extend the Axis: Extend the long axis of the Southern Cross by about 4.5 times its length.
- Estimate South: This point is approximately above the south celestial pole, indicating south.
Considerations:
- Light Pollution: Light pollution can make it difficult to see the stars, especially in urban areas.
- Cloud Cover: Cloud cover will obscure the stars, making this method impossible.
- Constellation Knowledge: Knowing how to identify the Big Dipper and Southern Cross is essential.
Example:
Lost in the Mongolian steppe at night, with a clear sky overhead. You locate the Big Dipper and use it to find Polaris, which guides you north toward a known landmark.
5. Observing Natural Indicators
Nature provides many subtle clues that can help you determine direction. Observing the growth patterns of plants, the behavior of animals, and the prevailing winds can offer valuable insights.
Examples of Natural Indicators:
- Moss Growth: In the Northern Hemisphere, moss tends to grow more abundantly on the north side of trees and rocks, as this side is typically shadier and damper. However, this is not a foolproof method, as local conditions can vary. This observation is less reliable in the Southern Hemisphere.
- Tree Rings: Tree rings are often wider on the side of the tree that faces the equator (south in the Northern Hemisphere, north in the Southern Hemisphere), as this side receives more sunlight and warmth.
- Prevailing Winds: Observing the direction of the prevailing winds can help you maintain a consistent course. In many regions, the winds tend to blow consistently from a particular direction.
- Animal Behavior: Observing the behavior of animals can also provide clues. For example, birds migrating south in the autumn can indicate the direction of south. Similarly, animal trails often lead to water sources or other essential resources.
- Snow Melt: Snow tends to melt more quickly on the south-facing slopes in the Northern Hemisphere and on the north-facing slopes in the Southern Hemisphere.
Considerations:
- Local Variations: Natural indicators can vary depending on local conditions, so it is essential to be aware of the specific characteristics of the environment.
- Reliability: Natural indicators are not always reliable on their own, but they can be useful when combined with other navigation methods.
- Experience: Interpreting natural indicators requires experience and careful observation.
Example:
Hiking through a dense forest in Patagonia. You notice that the moss is consistently thicker on one side of the trees. Knowing you're in the Southern Hemisphere, you infer that the thicker moss indicates the south side, helping you orient yourself.
