The correct answer is - the direction of the points of the V shapes on contour lines.
The contour lines can tell us a lot about the shape of the relief structures on the maps, and of the things that we can also see is the path of the rivers. When the rivers are running through a steeper part, practically their upstream, because they manage to cut and shape the relief structures around them, the contour lines take up a specific V shape. The points of the V are always on the river itself, and they point to the direction from where it is coming from, thus following the points of the V shape can bring us very easily to the upstream of the river.
