Which of the following is NOT a major terrain feature found on a map?

A cliff is not considered a major terrain feature on a standard map when compared to features like saddle, ridge, and depression. Major terrain features are typically defined as those that can significantly impact visibility, movement, and tactical considerations during operations. These include distinct formations that can be clearly identified and are generally larger in scale, such as ridges, saddles, and depressions, all of which can greatly influence the landscape and maneuverability in a military context.

While a cliff is an important geographical feature, it is usually classified as a minor terrain feature, given that it does not meet the same criteria of significance in terms of size and impact as the other options listed.
