![]() ![]() That would mean one place had two different elevations, which cannot happen. The contour lines run next to each other and NEVER cross one another.The bold contour lines are labeled with numerical elevations. Each contour line represents a specific elevation and connects all the places that are at the same elevation.Let's take a closer look at this (Figure 2.28). What makes a topographic map different from other maps? Contour lines help show various elevations.įigure 2.28: Topographic map of Swamp Canyon Trail portion of Bryce Canyon National Park.Ĭontour Lines and Intervals Ĭontour lines connect all the points on the map that have the same elevation. This type of map is called a topographic map (Figure 2.28). You need a special type of map to represent the elevations in an area. Where are the hills and valleys located? How high are the canyon walls? Which way will streams or rivers flow? But nothing on the map shows the height of the terrain. You see some markers for campsites, a picnic area, and a shuttle bus stop. You can see a green line which is the main road. Now look at the corresponding section of the Visitor's map (Figure 2.27). Figure 2.27: Portion of Bryce Canyon National Park road map. There are high and low points between the cliffs.įigure 2.26: View of Bryce Canyon National Park. The terrain clearly has many steep cliffs. You can see the rugged canyon walls and valley below. Look at this view of Bryce Canyon National Park, Utah (Figure 2.26). A topographic map will show you that the road bends to go around a hill or stops because that When you use a regular road map, you can see where the roads go, but a road map doesn't tell you why a road stops or bends. Contour lines are drawn on a topographic map to show the location of hills, mountains and valleys. Topographic maps use a special type of line, called a contour line, to show different elevations on a map. Topographic maps represent the locations of major geological features. ![]() Mapping is a crucial part of earth science.
