ビュート (地形)

{{翻訳途中}}

ビュート [bjuːt] は差別侵食によって形成された孤立丘。メサを参照。an isolated hill with steep, often vertical sides and a small, relatively flat top; buttes are smaller than mesas, plateaus, and table landforms. In some regions, such as the Midwestern United States and Northwestern United States, the word is used for any hill. The word butte comes from a French word meaning "small hill"; its use is prevalent in the Western United States, including the southwest, where "mesa" is also used for the larger landform. Because of their distinctive shapes, buttes are frequently landmarks in plains and mountainous areas.

In differentiating mesas and buttes, geographers use the rule of thumb that a mesa has a top that is wider than its height, while a butte has a top that is narrower than its height.
