A butte () is an isolated hill with steep, often vertical sides and a small flat top, smaller than mesas and plateaus. Buttes are prevalent in the western United States. The word "butte" comes from a French word meaning "small hill".
Distinction from mesaOne standard holds that a mesa has a surface area over 1,000 square meters, while a butte has a surface area less than 1,000 square meters (11,250 square feet). Geographers use the rule of thumb that a mesa has a top that is greater than three times its height, while a butte's top is less than three times its height.
FormationButtes are formed by erosion when a cap of hard rock, often of volcanic origin, covers a layer of softer rock that is easily worn away. The hard rock avoids erosion while the soft rock around it wears down. One example of a noted butte is Chimney Rock.
