Figure 26.6 Death Valley Topographic Map: from the 1000? contour line in Trail Canyon on the west side of Death Valley to the 200? contour line on the east side of Death Valley.
Use the following topographic maps and a ruler (inches or cm) to measure the map distance between the points indicated. Noting the RF scales posted on each map, calculate the approximate ground distance (miles or kilometers). Keep in mind that there are 63,360 inches in a mile: 12 in./ft * 5280 ft/ mile. Compare results with the graphic scale. What will be an ideal response?
