     Mr. King
        Hints to work with
        topographic maps.
· Small lines perpendicular to contour lines are
  called hachure lines.
· Hachure lines point downhill.
· Contour lines never cross.
· “V” shaped contour lines point up stream.
· A cross section line (X,Y) crosses contour lines
  to help determine cross section of land
· Contour lines explain elevation above sea
  level.
