- - Contour lines never cross. All lines on a contour line represent one elevation.
- - The spacing of contour lines depends on slope characteristics. Contour lines that are close together show a steep slope. Contour lines that are far apart show a gentle slope.
- - Contour lines that cross a valley or a stream are V shaped. The C points toward the area of the highest elevation. If a stream or river flows through the valley, the V points upstream.
- -The tops of the hills, mountains, and depressions are shown by closed circles. Depressions are marked with short, straight lines inside the circle that point down slope to the depression.

An index contour is a thicker contour line that is labeled with the elevation of that contour. It usually appears every fifth contour line and helps to quickly identify elevation changes on a topographic map. Regular contour lines are thinner and connect points of equal elevation.
What does a contour line indicate when it points downhill?
When a V-shaped contour line points downhill, it means that the contour line is under very low elevation. And incase your wondering about when the contour line is uphill, it means that the elevation level is very high.
