Moro Rock Stairway
Moro Rock is a granite dome rock formation in Sequoia National Park, California, United States. It is located in the center of the park, at the head of Moro Creek, between Giant Forest and Crescent Meadow. A stairway, designed by the National Park Service and built in 1931, is cut into and poured onto the rock, so that visitors can hike to the top. The view from the rock encompasses much of the Park, including the Great Western Divide. Use of this trail is discouraged during thunderstorms and when it is snowing. The name "Moro Rock" derives from a blue roan mustang of color the Mexicans call ''moro'', owned by one Mr. Swanson of Three Rivers in the 1860s Recreation The road to Moro Rock is closed in winter, so visitors need to hike 2 miles to reach the viewpoint. The road is open in summer so the hike is shortened. The 1996 general plan for the park calls for the road to Moro to be closed, and replaced by a shuttle. As of June 2012, the road is open to general traffic only dur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hospital Rock (Three Rivers, California)
Hospital Rock is a large quartzite rock in Sequoia National Park, located just off of the Generals Highway, on the Middle Fork of the Kaweah River. History Hospital Rock was once home to 500 Potwisha Native Americans. Archaeological evidence shows settlement as early as 1350, and bedrock mortar sites and pictographs remain. The Native Americans mostly used this site in the winter months. In 1860, Hale Tharp and his brother-in-law, John Swanson, were exploring the Giant Forest when Swanson sustained an injury to his leg. Swanson was transported to the locale where the injury was treated by local Indians. Hale Tharp gave the spot its name after a second similar incident. In 1873, James Everton recovered from a gunshot wound at the site. He had been injured by a shotgun snare set to trap bear. Visiting Hospital Rock is a public archaeological site that now features a parking lot and picnic area. A short trail was built by the Civilian Conservation Corps The Civilian Conse ...

Granite Domes
Granite domes are domical hills composed of granite with bare rock exposed over most of the surface. Generally, domical features such as these are known as bornhardts. Bornhardts can form in any type of plutonic rock but are typically composed of granite and granitic gneiss. As granitic plutons cool kilometers below the Earth's surface, minerals in the rock crystallize under uniform confining pressure. Erosion brings the rock closer to Earth's surface and the pressure from above the rock decreases; as a result the rock fractures. These fractures are known as exfoliation joints, or sheet fractures, and form in onionlike patterns that are parallel to the land surface. These sheets of rock peel off the exposed surface and in certain conditions develop domical structures. Additional theories on the origin of granite domes involve scarp-retreat and tectonic uplift. Sheet fractures Sheet fractures are arcuate fractures defining slabs of rock that range from 0.5 to 10 meters thic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Civilian Conservation Corps
The Civilian Conservation Corps (CCC) was a voluntary government work relief program that ran from 1933 to 1942 in the United States for unemployed, unmarried men ages 18–25 and eventually expanded to ages 17–28. The CCC was a major part of President Franklin D. Roosevelt's New Deal that supplied manual labor jobs related to the conservation and development of natural resources in rural lands owned by federal, state, and local governments. The CCC was designed to supply jobs for young men and to relieve families who had difficulty finding jobs during the Great Depression in the United States Robert Fechner was the first director of this agency, succeeded by James McEntee following Fechner's death. The largest enrollment at any one time was 300,000. Through the course of its nine years in operation, three million young men took part in the CCC, which provided them with shelter, clothing, and food, together with a wage of $30 (equivalent to $1000 in 2021) per month ($25 of ...

Spall
Spall are fragments of a material that are broken off a larger solid body. It can be produced by a variety of mechanisms, including as a result of projectile impact, corrosion, weathering, cavitation, or excessive rolling pressure (as in a ball bearing). Spalling and spallation both describe the process of surface failure in which spall is shed. The terms ''spall'', ''spalling'', and ''spallation'' have been adopted by particle physicists; in neutron scattering instruments, neutrons are generated by bombarding a uranium (or other) target with a stream of atoms. The neutrons that are ejected from the target are known as "spall". Mechanical spalling Mechanical spalling occurs at high stress contact points, for example, in a ball bearing. Spalling occurs in preference to brinelling where the maximal shear stress occurs not at the surface, but just below, shearing the spall off. One of the simplest forms of mechanical spalling is plate impact, in which two waves of compression ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exfoliation (geology)
Exfoliation joints or sheet joints are surface-parallel fracture systems in rock, and often leading to erosion of concentric slabs. ''(See Joint (geology)).'' General characteristics of exfoliation joints * Commonly follow topography. * Divide the rock into sub-planar slabs. * Joint spacing increases with depth from a few centimeters near the surface to a few meters * Maximum depth of observed occurrence is around 100 meters. * Deeper joints have a larger radius of curvature, which tends to round the corners of the landscape as material is eroded * Fracture mode is tensile * Occur in many different lithologies and climate zones, not unique to glaciated landscapes. * Host rock is generally sparsely jointed, fairly isotropic, and has high compressive strength. * Can have concave and convex upwards curvatures. * Often associated with secondary compressive forms such as arching, buckling, and A-tents (buckled slabs) Formation of exfoliation joints Despite their common occurrenc ...

Monolith
A monolith is a geological feature consisting of a single massive rock (geology), stone or rock, such as some mountains. For instance, Savandurga, Savandurga mountain is a monolith mountain in India. Erosion usually exposes the geological formations, which are often made of very hard and solid igneous rock, igneous or metamorphic rock. Some monoliths are volcanic plugs, solidified lava filling the vent of an extinct volcano. In architecture, the term has considerable overlap with megalith, which is normally used for prehistory, and may be used in the contexts of rock-cut architecture that remains attached to solid rock, as in monolithic church, or for exceptionally large stones such as obelisks, statues, monolithic columns or large architraves, that may have been moved a considerable distance after quarrying. It may also be used of large glacial erratics moved by natural forces. The word derives, via the Latin , from the Ancient Greek word (), from () meaning "one" or "sing ...

Peregrine Falcon
The peregrine falcon (''Falco peregrinus''), also known as the peregrine, and historically as the duck hawk in North America, is a Cosmopolitan distribution, cosmopolitan bird of prey (Bird of prey, raptor) in the family (biology), family Falconidae. A large, Corvus (genus), crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. The peregrine is renowned for its speed, reaching over during its characteristic hunting stoop (high-speed dive), making it the fastest bird in the world, as well as the Fastest animals, fastest member of the animal kingdom. According to a ''National Geographic (U.S. TV channel), National Geographic'' TV program, the highest measured speed of a peregrine falcon is . As is typical for avivore, bird-eating raptors, peregrine falcons are Sexual dimorphism, sexually dimorphic, with females being considerably larger than males. The peregrine's breeding range includes land regions from the Arctic tundra to the tropics. It can b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Climbing
Rock climbing is a sport in which participants climb up, across, or down natural rock formations. The goal is to reach the summit of a formation or the endpoint of a usually pre-defined route without falling. Rock climbing is a physically and mentally demanding sport, one that often tests a climber's strength, endurance, agility and balance along with mental control. Knowledge of proper climbing techniques and the use of specialized climbing equipment is crucial for the safe completion of routes. Because of the wide range and variety of rock formations around the world, rock climbing has been separated into several different styles and sub-disciplines, such as scrambling, bouldering, sport climbing, and trad (traditional) climbing another activity involving the scaling of hills and similar formations, differentiated by the rock climber's sustained use of hands to support their body weight as well as to provide balance. Rock climbing competitions have the objectives of either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mustang
The mustang is a free-roaming horse of the Western United States, descended from horses brought to the Americas by the Spanish. Mustangs are often referred to as wild horses, but because they are descended from once-domesticated animals, they are actually feral horses. The original mustangs were Colonial Spanish horses, but many other breeds and types of horses contributed to the modern mustang, now resulting in varying phenotypes. Some free-roaming horses are relatively unchanged from the original Spanish stock, most strongly represented in the most isolated populations. In 1971, the United States Congress recognized that "wild free-roaming horses and burros are living symbols of the historic and pioneer spirit of the West, which continue to contribute to the diversity of life forms within the Nation and enrich the lives of the American people". The free-roaming horse population is managed and protected by the U.S. Bureau of Land Management (BLM). Controversy surrounds the ...
