The sides are fairly vertical and the structure is made of soft rock. Looking at maps from that period (Permian) I would say, those buttes, were part of former North American continetal Fjords. Buttes can be found all over North America, though they are most commonly found in the arid regions of the American Southwest.For example, there is the Courthouse Butte, a prominent feature located just north of the Village of Oak Creek, and south of the town of Sedona in Yavapai County. The waves erode sea caves into the headland that eventually meet in the middle. The types of valleys include ravines, gorges, arroyos or wadis, canyons, and more. As Ashwin Vasavada, the Curiosity Project Scientist of NASA’s Jet Propulsion Laboratory, described the area as being “reminiscent of parts of the American southwest because of its butte and mesa landscape.
Volcanoes are also mountains, but they form by deposition. A rule of thumb might be that a steep-sided, isolated flat-topped hill is a mesa (from the Spanish word for table) unless it's too small to resemble a table, in which case it's a butte. This sea arch at Goat Rock Beach south of Jenner, California, is unusual in that it sits offshore. A rule of thumb might be that a steep-sided, isolated flat-topped hill is a mesa (from the Spanish word for table) unless it's too small to resemble a table, in which case it's a butte.
Geologists call such a stream a resequent stream. An equally important part of a yardang is the pair of wind-blown excavations, or yardang troughs, on either side of it. The Pacific shore in this photo is a place of wave erosion. The usual method of forming a sea arch is that a headland focuses incoming waves around its point and onto its flanks. Cirques are created by glaciers, grinding an existing valley into a rounded shape with steep sides. In the first, a glacier excavates a deep valley faster than a tributary glacier can keep up. To the local Hopi, Navajo, and other indigenous nations, these features – which resemble tall, isolated plateaus – have been regarded as sacred sites since time immemorial.By the beginning of the 19th century, the term “butte” entered common parlance and quickly became adopted by the geological community. Buttes are geographical landforms that have steep sides and a relatively flat top. Left exposed to the action of running water, the bare sides of the softer rock layers of buttes are eroded away over time.
This arch, in Arches National Park in Utah, formed by erosion of solid rock. Essentially, this involves the surface material of a hill or mountain (the cap rock) resists wind and water erosion, but the underlying materials do not.

This geographical feature is so-named because of the combination of a vertical side and a sloping side, which resemble the shape of an elephant.Bear Butte in South Dakota also has a long history of being a geological and cultural significant feature.
They may also be low ridges of rock without picturesque protuberances. A larger tableland may have buttes standing beyond its edges as outliers, left behind after erosion has carved away the intervening rock. Mesas are mountains with flat, level tops, and steep sides.
They are also beautiful in a way no other landscape can be.
Long before the arrival of European settlers, Bear Butte featured prominently in the religious and mythological traditions of the Lakota, Sioux and Cheyenne nations.
In America, a wash is a stream course that has water only seasonally. Another word for butte. First, rainwater is a very mild acid, and it dissolves cement in rocks with a calcite cement between its mineral grains.
In Pakistan and India, it is called a nullah. Another wave-cut platform lies under the surf.
These can be called buttes témoins or zeugenbergen, French and German terms mean"witness hillocks." A valley is any piece of low ground with the high ground around it.
As a result, when the softer rock is stripped away, a standing, isolated rock is left behind.
Dry-climate erosion, without the softening effects of soil or humidity, brings out the details of the sedimentary joints and cross bedding, carving suitable formations into suggestive shapes. Chimneys are smaller than stacks, which have a shape more like a mesa (see a stack here with a sea arch in it). They may also be called stream-cut terraces or platforms. A part of the geological formation known as the Chilcotin Group, this feature was formed roughly six million years ago as a result of the extensive volcanic activity in the region.Buttes have also been spotted on other planets in the Solar System, where they are also linked to geological activity and erosion. The front faces are undercut because wind-driven sand stays near the ground, and erosion is concentrated there. The bedrock knobs that survive on the platform are called chimneys. A gulch is a deep ravine with steep sides, carved by flash floods or other torrential streamflows. It is better described as an
Sinkholes are closed depressions that arise in two events: groundwater dissolves limestone, then the overburden falls into the gap.
Today, the location remains a sacred site for many indigenous peoples, who make pilgrimages to leave prayer cloths and tobacco bundles tied to branches taken from the trees that surround the butte.To the north, buttes can be found in the Canadian provinces of Saskatchewan, Alberta and British Columbia, in regions that are arid and semi-arid.
A gully is the first sign of serious erosion of loose soil by running water, although it does not have a permanent stream in it. Then there’s the Elephant Butte, which is located in the Elephant Butte Lake State Park in Sierra Country, New Mexico,. Other names for them are cloves and cloughs.
