What shape do contour lines typically take when representing a saddle?

Contour lines form a distinctive U or V shape when representing a saddle. A saddle is a landform that connects two hills or ridges and has a low point in the center. The U or V shapes of the contour lines illustrate this dip as they indicate a change in elevation. At the saddle point, the contour lines will typically show a decrease in elevation, forming a V shape that points uphill in both directions, which represents the higher terrain on either side. This is vital for navigation and understanding the topography, as it helps in identifying the direction of sloping land and the nature of the terrain you may encounter.
