Knowing how to read a topographic map is the foundation of any backcountry adventure. Through the use of contour lines, topo maps bring a 3-dimensional element to a 2-dimensional paper map. Topo maps allow you to visualize the rise and fall of the land and “see” the depths of canyons...
such as mountains, hills, valleys and rivers. Topographic maps are typically used by the military, architects, mining companies and even hikers. To read a topographic map, you need to understand the representations of the many circles and ...
Knowing how to read a USGS topographical map is essential to successfully finding a ghost town. USGS topographical maps are useful because they show the terrain and lay of the land as well as feature like roads, structures and mines. As you read this, it would be helpful if you also had...
Determine the area to be investigated. On a physical or digital map, establish the location of the area to be studied, noting the beginning and ending points. Acquire an elevation profile for this region. Consult a mapping tool such as Google Maps, MapQuest or Garmin for a topographical repr...
Different maps use different intervals, depending on the topography. If, for example, the general terrain is quite elevated, the map might run at 80- to even 100-foot (24- to 30-meter) intervals. This makes it easier to read the map — too many contour lines would be difficult to ...
Topographic maps use contour lines to show the elevation of an area. These lines have rules: they cannot cross, and they form circles around hills or depressions. Explore topographic and geologic maps, and learn how to read their contour lines, geologic markings, and colors. ...

Contour Maps U.S. Department of Commerce In this 1930 contour map from the U.S. Department of Commerce, you can see the roads, streams, railroads, place names, and other elements of any proper map. The shape of San Bruno Mountain is depicted by 200-foot contours, and a thicker contour...
The second thing you need to do to read a map is determine its orientation. North, south, east, and west are the four cardinal directions, and most maps (but certainly not all) will be oriented with north (meaning “true” north, as opposed to magnetic north) at the topmost portion of...
