Quick Answer
Understanding True North is essential for outdoor navigation because it provides a fixed reference point for orienting a map and compass, allowing individuals to accurately determine their direction of travel and location. This is crucial for staying on course, avoiding confusion, and making informed decisions in the wilderness. Without True North, navigation becomes increasingly challenging.
Understanding True North Basics
True North is the fixed point on the Earth’s surface that is 90 degrees from the equator, and it is also the direction of the Earth’s magnetic axis. To find True North using a compass, you need to know the difference between Magnetic North and True North. Magnetic North is the direction a compass needle points towards, and it is not always the same as True North. In most cases, Magnetic North is about 20 degrees away from True North.
Using a Compass to Find True North
To find True North using a compass, you need to adjust the compass needle so that the direction-of-travel arrow points towards Magnetic North. Then, you need to note the degrees difference between Magnetic North and the direction you want to travel. For example, if the difference is 20 degrees, you need to turn 20 degrees to the right of the direction-of-travel arrow to head towards True North. This is called “declination” and it’s essential to know the local declination value for your area to ensure accurate navigation.
Practical Applications in the Wild
When navigating in the wilderness, it’s crucial to know how to use a compass to find True North. This skill is especially important when using maps, as it allows you to accurately orient the map and determine your direction of travel. By understanding the difference between Magnetic North and True North, you can make informed decisions about your route and avoid getting lost. In addition, knowing how to use a compass to find True North is a fundamental skill that can be used in a variety of situations, from hiking and backpacking to search and rescue operations.
