    Figure 2.22: Topographic Map near Death Valley National Park.
    1. Determine the contour interval of the map. Show your work.

    2. What is the elevation at Point B?

    3. Interpolate the elevation at Point C. Hint: interpolation is the process of estimating an unknown value from neighboring known values.

    4. What is the elevation at Point A?

    5. Could a person standing at Point A see their friend located at Point C, with the aid of high-power binoculars? Why or why not?

    6. Could a person standing at Point D see their friend located at Point B, with the aid of high-power binoculars? Why or why not?

    7. Which area on this map has the steepest slope?

      • A

      • B

      • C

      • E

    8. How did you determine this?

    9. Calculate the gradient from Point A to Point B, in feet per mile (feet/mile). Hint: Use the scale bar to determine the distance from Point A to Point B. Show your work!
