A butte is a tall hill.
It has steep sides. The top is small and flat. Hard rock stays on top. Wind wears the rest away. It looks like a landmark. Can you find one in a book?
A butte is a tall hill.
It has steep sides. The top is small and flat.
Hard rock sits on the top. This rock protects the soft rock below. Wind wears the soft rock away.
This leaves the hill standing alone. The worn rock falls to the bottom. It makes a pile at the base.
Some buttes look like mittens.
They are famous landmarks.
One big butte is made of special rock. It is in Wyoming. These hills are very cool to see.
A butte is a tall hill. It stands alone in the land. It has steep sides. The top is small and flat.
Geographers use a rule to name them. A mesa is a wide landform. Its top is wider than its height. A butte is different. Its top is narrower than its height.
Buttes form through weathering and erosion. Weathering is when rock breaks down. Erosion is when wind or water carries it away. A hard layer called caprock sits on top. This hard rock protects the soft rock below. The wind wears away the soft rock. This leaves the hill standing alone.
Pieces of rock fall to the bottom. These piles are called talus slopes.
Many buttes are famous landmarks. The Mittens are in Monument Valley. They appear in many old movies. Devils Tower is another big butte. It is in Wyoming. It is made of igneous rock. This is rock made from cooled magma. Most buttes are made of sandstone or limestone.
A butte is a special kind of hill. It stands alone in a wide area. These hills have very steep sides. They also have a small and flat top.
Geographers use a rule to tell them apart from mesas. A mesa has a top that is wider than its height. A butte is different from a mesa. Its top is narrower than its height. This makes them look like tall towers.
Buttes form through a way it works called erosion. This happens when wind and water wear things away. First, a hard layer called caprock sits on top. This hard rock protects the softer rock underneath. The wind rubs against the soft rock. This leaves the hard top standing alone.
As the top wears down, pieces fall. These piles of rock are called talus slopes.
The word butte comes from a French word. That word means a knoll. A knoll is a small hill. People use this name often in the Western United States. You can find them in the Southwest. Some buttes even have different names. For example, Courthouse Rock is a name in Nebraska. These shapes make them great landmarks for travelers.
Many famous buttes exist in the United States. The Mittens are in Monument Valley. They sit on the Utah and Arizona state line. These buttes were in seven movies by John Ford.
Devils Tower is in Wyoming. It is a very well-known landmark. It is made of igneous rock. Most other buttes are made of sandstone or limestone.
Buttes are part of the big world around us. You might see them in movies or photos. Thumb Butte is a landmark in Arizona. It overlooks the city of Prescott. Some buttes are even mountains, like Crested Butte in Colorado. Others are islands, like Elephant Butte in New Mexico.
These landforms show how the earth changes over time.
In the study of geomorphology, a butte is a specific type of isolated hill. These landforms are characterized by very steep, often vertical sides. They also feature a relatively small and flat top. Buttes are smaller than other large landforms like mesas, plateaus, or tablelands. The term comes from the French word "butte," which means a knoll of any size. While the word can describe any small hill, it is very common in the Western United States. In the Southwest, the term is often used for much larger landforms.
Geographers use a specific rule of thumb to distinguish a butte from a mesa. A mesa is a large, flat-topped hill where the top is wider than the hill is tall. In contrast, a butte has a top that is narrower than its total height. This difference in proportions gives buttes their distinctive, tower-like appearance. Because of these unique shapes, they often serve as important landmarks. They can be found in both wide plains and mountainous regions.
Buttes form through the combined processes of weathering and erosion. The process begins when a layer of hard caprock sits atop a layer of less resistant rock. Caprock is a hard layer of stone that acts as a protective shield. As wind abrasion occurs, the wind wears away the softer rock underneath. However, the hard caprock resists this wear. This protection allows the softer rock to remain standing in an isolated shape.
As the erosion process continues, the butte changes over time. The top of the landform is further worn down by weathering and abrasion. Eventually, excess material breaks off from the structure. This fallen rock collects around the base of the hill. These piles of debris are known as scree or talus slopes. On a much smaller scale, this exact same process creates landforms called hoodoos. This shows how the same natural forces shape many different types of terrain.
Many famous buttes are located in the United States. The Mitten Buttes are two very famous examples. They are located in Monument Valley on the Utah and Arizona state line. These buttes are widely recognized because they appeared in many western-themed films. Specifically, they provided the background for seven movies directed by John Ford.
Another prominent landmark is Thumb Butte. It is located in northern Arizona and overlooks the city of Prescott.
Most buttes are composed of sedimentary rocks like sandstone or limestone. However, there are notable exceptions to this rule. Devils Tower in northeastern Wyoming is a very famous laccolithic butte. A laccolithic butte is formed from igneous rock rather than sedimentary layers.
This makes its geologic makeup quite different from the common sandstone buttes found elsewhere. This variety shows how different types of rock react to the forces of nature.
Sometimes the term "butte" is used more broadly or loosely. Some landforms have craggy or pointed tops rather than flat ones. For example, Scotts Bluff in Nebraska is a collection of five bluffs. Crested Butte in Colorado is actually a mountain. Elephant Butte in New Mexico is now an island in a reservoir. There are also large hills that use the name but but are not technically buttes. Examples include Kamiak Butte, Chelan Butte, and Steptoe Butte in Washington state. Many buttes also go by different names, such as Courthouse Rock in Nebraska.
