Butte
Encyclopedia : B : BU : BUT : Butte
A butte (IPA: [bju:t]) is an isolated hill with steep sides and a small flat top, smaller than mesas and plateaus. Buttes are prevalent in the western United States and on the Hawaiian Islands, especially around Honolulu. The word "butte" comes from a French word meaning "small hill."
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. One example of a noted butte is Chimney Rock.
Butte is the name of some cities in the United States. See Butte, Montana, Butte, Alaska, and Butte, Nebraska for more. There are also counties named Butte County.
