Method 1 assessing the contour lines. They show the world from a bird s eye view perpendicular to the ground. Some lines will have the recorded elevation written in the line. To read topographic maps you can assess the contour lines as well as the colors and symbols on the map.
The land survey information is a good example. At higher elevations mountains may be snow capped year around or the terrain may actually be a glacier. While most topo map users aren t trying to read the township range and section information it is still on the maps. Also known as topo maps these maps are so called planimetric maps.
They have a lot going on with different colors lines and labels all over the place. Your map will then be able to tell you a richly detailed tale about the terrain you ll be exploring. You can then orient yourself using the map so you do not get lost or turned around.
