Western Hill is a geographical term that refers to a region of the western United States. It is characterized by its hilly terrain and includes features such as buttes, mesas, and steppes. BUTTE is a geological formation that is typically steep-sided and flat-topped. It is usually formed by erosion and is found in areas with dry climates. Mesa is a landform that is similar to a BUTTE, but is much larger and has a more gradual slope. Steptoe is a type of mesa that is characterized by its stepped sides and flat top. All three of these features are commonly found in the Western Hill region.
