How are ridges represented on a topographic map?

On a topographic map, ridges are indicated by contour lines that point towards lower numbers on either side of the ridge. This representation visually shows the high point of the ridge and the descending slopes on both sides. As you move along the contour lines, the elevation rises to the peak of the ridge before dropping back down, which is essential for understanding the landform's shape and elevation changes.

Understanding that contour lines can reveal the steepness and direction of the slope is important in interpreting the topography effectively. The correct representation helps in planning and executing erosion and sediment control strategies, as it allows inspectors to identify areas susceptible to erosion based on the slope of the land.
