If we used a vertical scale identical to the horizontal scale, how many squares on the graph would accommodate the maximum relief along the profile?
A second example of a vertical profile is in Figure 23.6. Using the same procedure as you did on the previous assignment, construct a topographic profile. Label the South Fork of the Gualala River (see Figure 23.4, Step 3), the bench mark at 112 feet, and various road crossings on your profile. The coastline forms a contour line of equal elevation—sea level. Note the change in contour interval and scale from that of Figure 23.5. Use Figure 23.6 to answer further questions about preparing a topographic profile.
Less than five squares, or 671 ft.
