1, usually refer to the map and compass, actively observe the surrounding terrain and plants to judge the correct position.

Step 2 use the sun

In winter, the sunrise position is south-east and the sunset position is south-west; In summer, the sunrise position is north-east and the sunset position is north-west; Around the vernal equinox and autumnal equinox, the sunrise is due east and the sunset is due west.

As long as there is the sun, you can tell the direction with your watch. Read the time according to the 24-hour system, and divide the hour by 2 to get one hour. Put the watch horizontally on your hand or on the ground, so that the moment of the watch is aimed at the direction of the sun. At this time, the direction of 12 on the watch surface is north, and the direction of 6 o'clock is south.

Immediately, erect a pole on the ground. In the morning, the shadow points to the northwest, in the afternoon, the shadow points to the northeast, and the shortest shadow points to the north at noon.

Step 3 use stars

Aim for the North Star. First, find the spoon-shaped Big Dipper, and extend the interval between the two stars on the spoon C by five times. Then, you can find the Polaris on this straight line. The direction of Polaris is due north.

4. Use features to judge orientation.

Independent trees usually have lush foliage in the south, smooth bark in the north, sparse branches and rough bark. The south is generally thick with grass, while the north is wet and covered with moss.

For buildings and mounds, the snow in the north melts slowly, but in depressions such as potholes, the situation is just the opposite.

The doors and windows of large temples, pagodas and rural detached houses in northern China are mostly open to the south.

The northern edge of the clearing in the forest is covered with grass. The annual rings on the cross section of the stump are generally separated in the south and smaller in the north.

In the grassland and desert areas in northern China, many snow dragons and salons are often formed near the north wind and grassland. They have big heads and small tails, and their heads point northwest.

The doors of Mongolian yurts on the grassland are mostly facing south.

5 watch direction finding. "Half hour refers to the sun, 12 refers to the north". Generally, you can quickly identify the direction between 9 am and 4 pm. Aim at the sun half the time, 12 is north, for example, 14: 40 pm, and half is 7: 20 pm, so 65438. Or erect a stick in the center of the watch and turn the watch so that the shadow of the stick coincides with the hour hand. At this time, the bisector between 12 is the north.

That's all I know. I wonder if I can help you.
