video 10’05 : https://youtu.be/L1AWNR-Y0pQ?si=5WJaOtFURUew7Mpo : Understanding Topographic Maps : In this video we begin by looking at a topographic map of Pikes Peak in Colorado. I then build a clay model of a mountain and create cross sections representing different elevation layers. Using these layers we trace out the contour lines of the mountain to show how a three dimensional image of a landform can be mapped out on a topographic map.
