Physical Map of the United States

In this map taken from mapsoftheunitedstates.org, one can see a physical map of the United States of America. This map is intended to show the terrain of America by shading elevated areas as orange or purple while flatter areas are green. However, the map does not indicate the coloring in a legend. The only way to be certain of this is by looking at the Rocky Mountains or other known mountains and viewing the color scheme. The map does show a few major highways in red. Clearly, the map is only intended to show the terrain of only the United States as other countries are shaded plain gray. Also, the map names the states in a lighter shade than geographic names, such as the Appalachian Mountains. Furthermore, an interesting aspect of this map is that it shows the relative depths of the oceans by different shades as well.
