A butte (IPA: [bju:t]) is an isolated hill with steep sides and a small flat top, smaller than mesas and plateaus.
Buttes are formed by erosion when a cap of hard rock, usually of volcanic origin, covers a layer of softer rock that is easily worn away. This hard rock avoids erosion while the rock around it wears down.
