What do you think this odd formation is called, and where might you find one?
It’s called a mesa.
These land formations are hills with a flat top. A butte, a steep hill of rock with a flat top, is considered a smaller version of a mesa. These can be found in the southwest region of the United States. Other regions in the world are known to have mesas, including Spain, Sardinia, North and South Africa, Arabia, India, and Australia.
The southwest region contains many other landforms as well. This region is composed of four states:
- New Mexico
These states are considered to have a semi-arid steppe climate in the western area and more humid climate in the east. In addition, some of the regions farther west have an alpine or desert climate.
- Semi-arid steppe climate that is semi-dry and typically gets less than 20 inches of rain per year
- Alpine average climate for regions above the tree line. Extremely cold and dry throughout the year.
- Desert climate climate that receives less than 10 inches of precipitation a year, making it impossible to sustain vegetation in the area

The southwest region is considered to lie in the “rain shadow” because it is on the dry side of the mountains that block the ocean air. This effect creates a dry climate with lower precipitation. If it rains, it is typically in bursts. This region is also well known for the minerals, fuels, and forests it contains.
