How to discern direction in the field, how to discern direction in the wild?

When the magnetic needle of the compass is stationary, the direction pointed to by its n end (usually marked) is north. With the popularization of modern navigation technology, the lightweight and rechargeable GPS will provide more accurate help for the identification and help of field locations. Looking at the direction of the watch with the watch "the hour folds half to the sun, 12 refers to the north", generally between 9 a.m. and 4 p.m., you can quickly identify the direction, with half of the time pointing to the direction to the sun, 12 hours is the north, such as 14 p.m

The time of 40, half of which is 7:20, is directed towards the sun, so 12 refers to the north. Using the sun, the sun rises in the east and sets in the west, which is the most basic way to identify the direction.

It can also be measured by the shadow formation method of the wooden stick, when the sun is enough to form a shadow, a straight stick (more than 1 meter) is erected on the flat ground, and a stone is placed on the top of the shadow of the wooden stick (or other marker), and the shadow of the wooden stick will move with the movement of the sun. After 30 60 minutes, place another stone on the top of the shadow of the stick again. Then draw a straight line between the two stones, and in the middle of this line a straight line that intersects perpendicular to it.

Then step on the first marker point with your left foot and the second marker with your right foot. At this time, the front of the person standing is due north, the back is due south, the right hand is east, and the left hand is west. Use plant growth to judge the direction as the saying goes:

Everything depends on the sun for growth", and by mastering this characteristic, it is possible to determine the direction by observation even on cloudy days without the sun. For example, the grass on the south side of the main trunk of large rocks and trees grows more vigorously, and the grass on the south side also withers faster in autumn; The bark of the tree is generally smoother in the south and coarser in the north, and some trees have many cracks and pimples on the bark of the north side, which is particularly obvious on birch trees; Pine and cedar trees have more gum on the trunk than in the north, and are prone to form larger lumps. In autumn, many fruit trees bear more south-facing fruits, especially apples, red dates, persimmons, citrus, etc., and the fruits also change color first-facing when they are ripe. The moss that grows on the stones likes to be shaded and damp, and the north side is prosperous; The snow melts mostly on the south-facing side first; There is a clear distinction between the north and south of the tree heads (places with dense foliage), with dense in the direction of the south and sparse in the direction of the north.

The direction of the sun, houses, tree canopies, tree rings, and the direction of rivers can all be recognized.

Look at the North Star, which hangs forever in the north.

There are two kinds of directions that rely on the sun to discern directions. The sun comes out in the east. From the west road.

1. The sun. The sun rises in the east and sets in the west, which is the most basic way to identify the direction. It can also be measured by the shadow method of wooden sticks, on a sunny day, a wooden stick is erected on the ground, and the shadow of the wooden stick moves with the change of the position of the sun, these shadows are shortest at noon, and the line at its end is a straight line, and the vertical line of the straight line is in the north-south direction.

2. Daystar.

In the early hours of the morning, one can see the bright planet Venus, known as the "morning star", in the eastern sky. In the days when there were no clocks, people judged the arrival of dawn by the rising star of the day; At dusk, Venus appears in the western sky, bright and bright, called "Chang Gung Star".

3. Annual rings. Clear rings can be seen on the cross-section of the trunk of the tree, with sparse rings on the south side and dense rings on the north side.

4. The moon. The crescent moon on the third and fourth days of the first month, low in the western sky at sunset; In the first half moon of the seventh or eighth month, when the sun has just set, it takes a loss overhead. At the middle of the moon, as soon as the sun goes down, the moon rises in the east.

The direction of the moon at night is: first quarter moon, 6 p.m. in the south, and 12 p.m. in the west. Full Moon (14th-18th), 6 p.m. in the east, 12 p.m. in the south, and 6 a.m. in the west the next morning.

At the end of the quarter, at 12 o'clock in the east at night, and at 6 o'clock in the south the next morning.

5. Moss. Mosses that grow on stones are damp and intolerant to sunlight, so moss usually grows on the north side of the stones.

6. Anthill cave door.
