Question

Using the “Mauna Loa, Hawaii” topographic map (scale 1:250,000; contour interval 200 feet), calculate the gradient of Mauna Loa (19°28_17_N, 155°35_41_W) along line AB, from the 6000_, contour (near Point A) toward the summit. (On the edge of a piece of paper you can measure out a distance of 10 miles using the graphic map scale in the left top corner of the map, and then determine the elevation change over that distance.)
Record elevation by point A _______________ feet
Draw the AB line and record elevation near the summit along the AB line _________________feet
Find the elevation change (difference) _____________________feet
The distance between your recorded elevations should be approximately 10 miles
Calculate the gradient and show your work below

(Elevation Change)

feet ÷

(Number of Miles)

(Gradient)

Feet/mile
