Directions: Study the contour map below. Using the contour map and what you learned from the lesson, complete the questions below. When your report is finished, submit it to the 1.04 Topographic Lab Dropbox for grading. This assignment is worth 20 points. Analysis Questions

1. What is the contour interval?
The solid lines on this map are contour lines indicating points with the same elevation. Look for numbers on some of the contour lines indicating the elevation. Notice that not every contour line is numbered to keep the map from becoming cluttered. Find the contour interval by figuring out how far apart the contour lines are from each other. For example, how are we going to count to get from the 100 ft. contour line to the 200 ft. contour line? Divide the difference in elevation (200 ft. minus 100 ft.) by how many strips of land are between the 100 ft. and 200 ft. contour lines.

2. What is the elevation at point C?
Hint: You will need to use the contour interval from question #1 to correctly label the contour lines between 200 ft. and 100 ft.


(4 points)
3. What is the highest possible elevation at point D? If you were standing at this location and looked south, toward the railroad track, would you mostly be looking up or down?


(4 points)
4. Imagine you are standing at point E on the top of Pine Peak. On what side do you find the steepest slope? How do you know? Use the words “contour lines” in your answer.

5. Is Blue River flowing northeast or southwest? How can you tell?


(3 points)
6. Why would it be useful to have a topographic map? Identify two different individuals who might use this kind of map.
Hint: Review the purpose of a topographic map and think of different careers or hobbies that would need the type of information a topographic map provides.
