The geographical term for a steep hill or mountain is a butte or hill. Buttes typically have flat tops and steep sides, formed through erosion processes that wear away softer surrounding rock layers. They are often found in arid regions, where sedimentary rock formations are prevalent. The distinct shape of buttes makes them easily recognizable in the landscape. This feature contributes to the complexity of geological studies and offers unique habitats for various plant and animal species. Notable examples of buttes can be found in the American West, such as Monument Valley.
