The best way to maintain a bergain on an unknown, unfamiliar terrain is to track contour lines on a topographic map. Topographic map with contour lines shows valleys and hills, steepness or gentleness of slopes. The contour interval on the topographic map is the difference in height between consecutive contour lines. Contour lines (thinner lines) are located between the index contours, and they are called the intermediate contour lines. For example, if the data is given on the map, 100: 5 = 20, this means that the difference in height between the index lines is 100 meters, and the height difference of two adjacent contour lines is 20 meters. In this way, the characteristic of the unknown terrain can be determined, steepness, gentleness, etc.
