What do hachures on a contour indicate?

Explanation:
Hachures indicate a depression in the land. The short lines on a contour line point toward the lower ground, i.e., the downhill direction, signaling that the terrain dips inward to a hollow. Seeing hachures on the downhill side of a depression contour tells you that elevation is dropping as you move toward that side, which is the hallmark of a hollow rather than a peak or saddle.
