n.
(French: "hillock" or "rising ground") Flat-topped hill surrounded by a steep cliff, from the bottom of which a slope descends to the plain.
The term is sometimes used for an elevation higher than a hill but not high enough to be a mountain. Buttes topped by horizontal platforms of hard rock are characteristic of the arid plateau region of the western U.S. A butte is similar to a mesa but generally smaller; both are created by erosional processes.
