After a while, you'll get tired and start to forget. This step with a big 50 painted on it means that you're now 50 feet above sea level. This information will either be printed on the map somewhere or you can figure it out by looking at the index contours.Well lucky for you, after your 50 stairs, you see a painted step that has a big 5-0 printed on it. Each index contour might only be labeled in two or three other places - it keeps the clutter down. Now, lines can (and often do) get really close to each other.
These lines would circle all the way around the mountain you just created and would be very similar to something called a topographic map.
A topographic map is a type of map that shows elevation.
Free 5-day trial This lesson explains the main features of topographic maps, including contour lines, index contours and contour intervals.
It will also cover two rules that all contours follow and discuss geologic maps and the information they contain. Golden banana slices on the bottom, two or three nice big scoops of frosty ice cream, warm caramel & chocolate, maybe even some bright sprinkles…Oh and don't forget the best part, the whipped cream.

One different thing about topographic maps: They have rules. The closer those lines, the steeper the hill would be.
Specifically, the contour lines have rules - and every topographic map follows them: 1. A sheer cliff would have lines all piled up to show that drastic elevation change, and a gentle slope would have contour lines much more spread out. This is a topographic map that would represent this type of cliff landform.
Each line is a different elevation, but some of these lines have numbers on them. Index contours display the exact elevation of one specific line. Maybe you're at the Pyramids of Giza or one of those big concrete sports arenas or any other place where there's lots of steps. If you start hiking up the stairs, the tenth step up would be painted light brown. If you went up another 10 steps, there would be another step painted brown there as well. While we're focused on lines here, look at the space between any two lines. Contour interval is the distance between any two side-by-side lines.
