Mushroom Rock
A mushroom rock, also called rock pedestal, or a pedestal rock, is a naturally occurring rock whose shape, as its name implies, resembles a mushroom. The rocks are deformed in a number of different ways: by erosion and weathering, glacial action, or from a sudden disturbance. Mushroom rocks are related to, but different from, ''yardang''. A mushroom rock, rock pedestal, or gour is a typical mushroom-shaped landform that is formed by the action of wind erosion. At an average height of from the base, the material-carrying capacity of the wind is at its maximum, so abrasion (erosion by wind in which transported materials hit an exposed rock surface and polish it or scratch it) is also maximized. In some cases, harder rocks are arranged horizontally over a softer rock, resulting in such erosion. Erosion Usually found in desert areas, these rocks form over thousands of years when wind erosion of an isolated rocky outcrop progresses at a different rate at its bottom than at its top. ...

Mushroom In Timna Park In Summer 2011 (1)
A mushroom or toadstool is the fleshy, spore-bearing Sporocarp (fungi), fruiting body of a fungus, typically produced above ground, on soil, or on its food source. ''Toadstool'' generally denotes one poisonous to humans. The standard for the name "mushroom" is the cultivated white button mushroom, ''Agaricus bisporus''; hence the word "mushroom" is most often applied to those fungi (Basidiomycota, Agaricomycetes) that have a stem (Stipe (mycology), stipe), a cap (Pileus (mycology), pileus), and gills (lamellae, sing. lamella (mycology), lamella) on the underside of the cap. "Mushroom" also describes a variety of other gilled fungi, with or without stems, therefore the term is used to describe the fleshy fruiting bodies of some Ascomycota. These gills produce microscopic Spore#Fungi, spores that help the fungus spread across the ground or its occupant surface. Forms deviating from the standard morphology (biology), morphology usually have more specific names, such as "bolete", "p ...

Ventifact
A ventifact (also wind-faceted stone, windkanter) is a rock that has been abraded, pitted, etched, grooved, or polished by wind-driven sand or ice crystals. These geomorphic features are most typically found in arid environments where there is little vegetation to interfere with aeolian particle transport, where there are frequently strong winds, and where there is a steady but not overwhelming supply of sand. Ventifacts can be abraded to eye-catching natural sculptures such as the main features of the White Desert National Park near Farafra oasis in Egypt. In moderately tall, isolated rock outcrops, mushroom shaped pillars of rock may form as the outcrop is eroded by saltating sand grains. This occurs because, even in strong winds, sand grains can't be continuously held in the air. Instead, the particles bounce along the ground, rarely reaching higher than a few feet above the Earth. Over time, the bouncing sand grains can erode the lower portions of a ventifact, while leaving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precarious Boulder
A balancing rock, also called a balanced rock or precarious boulder, is a naturally occurring geological formation featuring a large rock or boulder, sometimes of substantial size, resting on other rocks, bedrock, or on glacial till. Some formations known by this name only appear to be balancing, but are in fact firmly connected to a base rock by a pedestal or stem. No single scientific definition of the term exists, and it has been applied to a variety of rock features. Categories Types of feature that the term has been applied to include: ;Glacial erratic: A boulder that was transported and deposited by glaciers or ice rafts to a resting place on soil, on bedrock, or on other boulders. It usually has a different lithology from the other rocks around it. Not all glacial erractics are balancing rocks; some are firmly seated on the ground. Some balancing erractics have come to be known as rocking stones, also known as logan rocks, logan stones, or logans, because they are so fin ...

Hoodoo (geology)
A hoodoo (also called a tent rock, fairy chimney, or earth pyramid) is a tall, thin spire of rock formed by erosion. Hoodoos typically consist of relatively soft rock topped by harder, less easily eroded stone that protects each column from the elements. They generally form within sedimentary rock and volcanic rock formations. Hoodoos range in size from the height of an average human to heights exceeding a 10-story building. Hoodoo shapes are affected by the erosional patterns of alternating hard and softer rock layers. Minerals deposited within different rock types can cause hoodoos to have different colors throughout their height. Etymology In certain regions of western North America these rocky structures are called hoodoos. The name is derived from Hoodoo spirituality, in which certain natural forms are said to possess certain powers, but by the late 19th century, this spirituality became associated with bad luck. Prior to the English name for these geographic formations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeolian Processes
Aeolian processes, also spelled eolian, pertain to wind activity in the study of geology and weather and specifically to the wind's ability to shape the surface of the Earth (or other planets). Winds may erode, transport, and deposit materials and are effective agents in regions with sparse vegetation, a lack of soil moisture and a large supply of unconsolidated sediments. Although water is a much more powerful eroding force than wind, aeolian processes are important in arid environments such as deserts. The term is derived from the name of the Greek god Aeolus, the keeper of the winds. Definition and setting ''Aeolian processes'' are those processes of erosion, transport, and deposition of sediments that are caused by wind at or near the surface of the earth. Sediment deposits produced by the action of wind and the sedimentary structures characteristic of these deposits are also described as ''aeolian''. Aeolian processes are most important in areas where there is little or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wadi Rum
Wadi Rum ( ar, وادي رم ''Wādī Ramm'', also ''Wādī al-Ramm''), known also as the Valley of the Moon ( ar, وادي القمر ''Wādī al-Qamar''), is a valley cut into the sandstone and granite rock in southern Jordan, about to the east of Aqaba. With an area of it is the largest wadi in Jordan. Name Wadi Rum or ''Wadi Ramm'' is believed to get its name from the early name of Iram of the Pillars ( also called "Irum ( ar, إرم)" ), a lost city mentioned in the Quran. History Wadi Rum has been inhabited by many human cultures since prehistoric times, with many cultures–including the Nabataeans–leaving their mark in the form of petroglyphs, inscriptions, and a temple. In the West, Wadi Rum may be best known for its connection with British officer T. E. Lawrence, who passed through several times during the Arab Revolt of 1917–18. In the 1980s one of the rock formations in Wadi Rum, originally known as "Jabal al-Mazmar" (''The Mountain of (the) Plague''), w ...

Hopewell Rocks
The Hopewell Rocks, also called the Flowerpots Rocks or simply The Rocks, are rock formations known as sea stacks caused by tidal erosion in the Hopewell Rocks Ocean Tidal Exploration Site at the Hopewell Rocks Provincial Park in New Brunswick, Canada. They stand 40–70 feet tall. They are located on the shores of the upper reaches of the Bay of Fundy at Hopewell Cape near the end of a series of Fundy coastal tourism hubs including Fundy National Park and the Fundy Trail. Due to the extreme tidal range of the Bay of Fundy, the base of the formations are covered in water twice a day. It is possible to view the formations from ground level at low tide. The formations consist of red-brown sedimentary conglomerate, sandstone, and minor mudstone rock from the Carboniferous Hopewell Cape Formation, part of the Mabou Group. The large volume of water flowing in to and out of the Bay of Fundy modifies the landscape surrounding it. After the retreat of the glaciers in the region follo ...

Phae Mueang Phi
Phae Mueang Phi ( th, แพะเมืองผี, ) is a place with original rock formations in the Phi Pan Nam Range, Thailand. It is about eight kilometres northeast of Phrae town in Mueang Phrae District, Phrae Province. Named after the local ghosts (ผี), the zone of Phae Mueang Phi includes mushroom rocks and distinctive pillars shaped by natural erosive action. The term ''Phae Mueang Phi'' is northern expression meaning 'ghost town grove' because the terrain is otherworldly. Protected area Phae Mueang Phi Forest Park is a small protected area covering the site that was established on 8 March 1981. The name "forest park" is a category, for there is no forest as such at the site except for a few scattered trees. The protected zone covers an area of 0.27 km2.

Mushroom Rock State Park
Mushroom Rock State Park is noted for its mushroom rock formations. It is located in the Smoky Hills region of north-central Kansas in Ellsworth County, Kansas, United States. These rocks are the remains of beach sands and sediments of the Cretaceous Period, the interval of geologic time from about 144 to 66 million years ago. Sandstone and sedimentary rock is held together by natural cement. The concretions that make up Mushroom Rocks are cemented calcium carbonate. The largest rock measures 27 feet in diameter. There are two mushrooms and a giant shoe rock, as well as numerous other rock formations in the park. Mushroom Rock is Kansas's smallest state park. As well as being "one of the 8 wonders of Kansas Geography." Mushroom Rock State Park is managed by Kanopolis State Park, under regulation of Kansas Department of Wildlife, Parks and Tourism. The rock used to serve as meeting places for pioneers and Native Americans. Gallery File:Mushroom Rock Kansas 1916.jpg, Rock f ...
