Identify the direction:

When traveling in the wild, you must learn to tell the direction. We all know the pointing function of compass. Here are some other ways to tell the direction in the wild:

Contour: a line that artificially connects points with the same or similar geographical height, that is, a contour line. Generally, the height difference of contour lines is equal, depending on the map scale, generally between 50 and 200 meters. By looking at the distribution and density of contour lines, we can imagine the general terrain. The color blocks of contour lines change with the elevation. The elevation rises in light brown, and the elevation changes from dark brown to dark brown. When it snows all the year round, it appears white (with dotted lines on the side), and the altitude drops to a certain extent, which is generally marked with green. Don't think it is a forest, and don't think it is an oasis. If it is a closed contour line, it means a mountain peak or depression or funnel landform; If the contour lines become dense and merge together, they are steep cliffs and cliffs; If the contour lines are sparse, it means that the terrain is gentle slope or flat land; If the contour line is zigzag, it is a ravine. Map orientation: the orientation of most regional maps is the north, south, west and east of the drawing. It is very important to recognize this point, which needs to be clear when planning the activity itinerary.

Legend: All maps have some symbols, lines and so on. To express a certain geographical terrain type. Such as roads, lakes, grasslands, rivers, villages and towns, peaks and so on. There are legends on general maps.

Observe the sky: The most common way to observe the sky is to observe Polaris. At night, in the dark night sky, we always find the Beidou constellation shaped like a spoon. Seven times from the end of the spoon, there is a bright star, the Polaris, which is directly below the north and clockwise is east, south and west.

Sun and Moon: The sun rises in the east and sets in the west. Observing the sunrise and sunset can generally show a general direction. You can also use the following methods to measure: erect a straight stick (1 meter high or above) on the flat ground, first make a mark on the top of the shadow of the straight stick (such as putting a stone), and the shadow of the straight stick will move with the movement of the sun. After 65,438+00-60 minutes, make another mark above the shadow of the stick, and draw a straight line between the two marks, which is vertical in the middle.
