Whether a charcoal and parchment treasure map or multi-colored, plastic-coated, trail map, maps tell a story of the world around us. Maps help us to locate places, measure distances, and find where we are on the earth.

Reading maps is not usually difficult because there are some rules that are generally followed when creating and reading maps:North, South, East, and West are the four main "cardinal" directions.On a map, North is at the top, South at the bottom, West to the left, and East to the right.Using the scale of a map, you can tell the actual distance between two points for real.Maps use colors to share more information. Blue often means water, green means forest, and white means bare land.A map has a Legend which lists the symbols it uses and what they mean.A grid of imaginary lines wrap around and over the earth. These lines are called Latitude and Longitude and can identify the exact location of any point on earth.Keeping those things in mind, you can read pretty much any map and especially learn how to read a topographic or topo map for navigation in the back country.

Here are some exercises to help you learn how to read a map:

Basic Map Parts

*
This simple road direction map contains a lot of information:North is marked in the upper-left corner so you know which way this map relates to the world.The Scale is marked. One inch equals 5 miles, so you can tell it is about 15 miles from Seattle to Woodinville.Main roads are included so you can find the best route direction between two locations.Roads are labeled so you know what to look for when navigating.Bodies of water are colored blue.So, you can see even a simple road map is packed with good direction and navigation information. The maps we use for hiking are even more packed with details.

Maps or Photos

*
The topo map above represents the land in the aerial photo. Notice the buildings and roads on the map can be seen in the photo. Move your mouse over the photo to see the objects highlighted.A navigation map is actually more useful than a photograph since it can highlight important items and ignore clutter like trees and shadows.

Shaded Relief Maps

*
Adding shading to denote shadows thrown by the sun and colors to denote elevation change, beautiful and somewhat realistic maps can be created. The example above shows a high mountain in white in the NorthEast (upper-right) with elevation dropping to a low, flat plain in the SouthWest (lower-left). Mountains, ridges, cliffs, canyons, and plateaus can all be identified.Shaded relief adds depth and interest to a map, but more is needed to make a map truly useful to us hikers and explorers for navigating wild areas.
