Flat topped hills or rock formations with steep walls on all sides are called a mesa. See the related links for more information. A plateau is a large ( as in many square miles), extended area, that is higher than the surrounding land
This could be a mesa (up to a few miles wide) or a plateau (up to hundreds of miles wide).
A landform with steep sides and a flat top is typically called a plateau. Plateaus are elevated flatlands that rise sharply above surrounding areas, forming a table-like structure. They are often the result of processes like erosion, volcanic activity, or tectonic uplift.
A mesa is an isolated, flat-topped elevation, ridge or hill, which is bounded from all sides by steep escarpments and stands distinctly above a surrounding plain
