How do you show depression on a topography map?
Depressions on a topographic map are indicated by closed contour lines that form a circular shape with the highest elevation on the outermost line. The contour lines within the depression draw inwards, with each subsequent line representing a lower elevation. Additionally, hachure marks or tick marks on the contour lines can be used to emphasize the downward slope of the depression.
