Titus Canyon Narrows
Titus Caesar Vespasianus ( ; 30 December 39 – 13 September 81 AD) was Roman emperor from 79 to 81. A member of the Flavian dynasty, Titus succeeded his father Vespasian upon his death. Before becoming emperor, Titus gained renown as a military commander, serving under his father in Judea during the First Jewish–Roman War. The campaign came to a brief halt with the death of emperor Nero in 68, launching Vespasian's bid for the imperial power during the Year of the Four Emperors. When Vespasian was declared Emperor on 1 July 69, Titus was left in charge of ending the Jewish rebellion. In 70, he besieged and captured Jerusalem, and destroyed the city and the Second Temple. For this achievement Titus was awarded a triumph; the Arch of Titus commemorates his victory to this day. During his father's rule, Titus gained notoriety in Rome serving as prefect of the Praetorian Guard, and for carrying on a controversial relationship with the Jewish queen Berenice. Despite ...

Anticline
In structural geology, an anticline is a type of fold that is an arch-like shape and has its oldest beds at its core, whereas a syncline is the inverse of an anticline. A typical anticline is convex up in which the hinge or crest is the location where the curvature is greatest, and the limbs are the sides of the fold that dip away from the hinge. Anticlines can be recognized and differentiated from antiforms by a sequence of rock layers that become progressively older toward the center of the fold. Therefore, if age relationships between various rock strata are unknown, the term antiform should be used. The progressing age of the rock strata towards the core and uplifted center, are the trademark indications for evidence of anticlines on a geologic map. These formations occur because anticlinal ridges typically develop above thrust faults during crustal deformations. The uplifted core of the fold causes compression of strata that preferentially erodes to a deeper st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prospecting
Prospecting is the first stage of the geological analysis (followed by exploration) of a territory. It is the search for minerals, fossils, precious metals, or mineral specimens. It is also known as fossicking. Traditionally prospecting relied on direct observation of mineralization in rock outcrops or in sediments. Modern prospecting also includes the use of geologic, geophysical, and geochemical tools to search for anomalies which can narrow the search area. Once an anomaly has been identified and interpreted to be a potential prospect direct observation can then be focused on this area. In some areas a prospector must also make claims, meaning they must erect posts with the appropriate placards on all four corners of a desired land they wish to prospect and register this claim before they may take samples. In other areas publicly held lands are open to prospecting without staking a mining claim. Historical methods The traditional methods of prospecting involved combi ...

Leadfield, California
Leadfield was an unincorporated community, and historic mining town in Inyo County, California. It is now a ghost town. It is located in Titus Canyon in the Grapevine Mountains, east of Death Valley in Death Valley National Park. Leadfield lies at an elevation of . It is on the National Register of Historic Places. History Ore was being exploited in Titus Canyon as early as 1905, but the townsite of Leadfield at the head of the canyon dates to the years 1925 and 1926. The product of extensive and fraudulent advertising by the Western Lead Mine Company and C.C. Julian, the town boomed in 1925. His advertising posters showed steamboats navigating the Amargosa River to Leadfield, ignoring the fact that the Amargosa River is dry much of the time and does not run within 20 miles of Leadfield. Fifteen miles of road were built up the canyon to connect with the road to Beatty, Nevada, a concrete foundation for a stamp mill was poured, and the beginning of a series of power poles for ...

Spring (hydrosphere)
A spring is a point of exit at which groundwater from an aquifer flows out on top of Earth's crust (pedosphere) and becomes surface water. It is a component of the hydrosphere. Springs have long been important for humans as a source of fresh water, especially in arid regions which have relatively little annual rainfall. Springs are driven out onto the surface by various natural forces, such as gravity and hydrostatic pressure. Their yield varies widely from a volumetric flow rate of nearly zero to more than for the biggest springs. Formation Springs are formed when groundwater flows onto the surface. This typically happens when the groundwater table reaches above the surface level. Springs may also be formed as a result of karst topography, aquifers, or volcanic activity. Springs also have been observed on the ocean floor, spewing hot water directly into the ocean. Springs formed as a result of karst topography create karst springs, in which ground water travels throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timbisha
The Timbisha ("rock paint", Timbisha language: Nümü Tümpisattsi) are a Native American tribe federally recognized as the Death Valley Timbisha Shoshone Band of California. They are known as the Timbisha Shoshone Tribe and are located in south central California, near the Nevada border. As of the 2010 Census the population of the Village was 124. The older members still speak the ancestral language, also called Timbisha. History The Timbisha have lived in the Death Valley region of North America for over a thousand years. They were originally known as Panamints, as was their Uto-Aztecan language. The band traditionally was very small in size, and linguists estimate that fewer than 200 individuals ever spoke Panamint Shoshone. Euro-Americans first made contact with the Timbisha Shoshone during the California Gold Rush of 1849, but whites quickly moved on to the gold fields, leaving the Shoshone homeland with its current daunting name. Sustained contact occurred during the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breccia
Breccia () is a rock composed of large angular broken fragments of minerals or rocks cemented together by a fine-grained matrix. The word has its origins in the Italian language, in which it means "rubble". A breccia may have a variety of different origins, as indicated by the named types including sedimentary breccia, tectonic breccia, igneous breccia, impact breccia, and hydrothermal breccia. A megabreccia is a breccia composed of very large rock fragments, sometimes kilometers across, which can be formed by landslides, impact events, or caldera collapse. Types Breccia is composed of coarse rock fragments held together by cement or a fine-grained matrix. Like conglomerate, breccia contains at least 30 percent of gravel-sized particles (particles over 2mm in size), but it is distinguished from conglomerate because the rock fragments have sharp edges that have not been worn down. These indicate that the gravel was deposited very close to its source area, since otherwise th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Canyon
The Grand Canyon (, yuf-x-yav, Wi:kaʼi:la, , Southern Paiute language: Paxa’uipi, ) is a steep-sided canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is long, up to wide and attains a depth of over a mile (). The canyon and adjacent rim are contained within Grand Canyon National Park, the Kaibab National Forest, Grand Canyon–Parashant National Monument, the Hualapai Indian Reservation, the Havasupai Indian Reservation and the Navajo Nation. President Theodore Roosevelt was a major proponent of the preservation of the Grand Canyon area and visited it on numerous occasions to hunt and enjoy the scenery. Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted.

Lake Mead National Recreation Area
Lake Mead National Recreation Area is a U.S. national recreation area in southeastern Nevada and northwestern Arizona. Operated by the National Park Service, Lake Mead NRA follows the Colorado River corridor from the westernmost boundary of Grand Canyon National Park to just north of the cities of Laughlin, Nevada and Bullhead City, Arizona. It includes all of the eponymous Lake Mead as well as the smaller Lake Mohave – reservoirs on the river created by Hoover Dam and Davis Dam, respectively – and the surrounding desert terrain and wilderness. Formation of Lake Mead began in 1935, less than a year before Hoover Dam was completed. The area surrounding Lake Mead was protected a bird refuge in 1933, later established as the Boulder Dam Recreation Area in 1936 and the name was changed to Lake Mead National Recreation Area in 1947. In 1964, the area was expanded to include Lake Mohave and its surrounding area and became the first National Recreation Area to be designated as such ...

Stromatolite
Stromatolites () or stromatoliths () are layered sedimentary formations (microbialite) that are created mainly by photosynthetic microorganisms such as cyanobacteria, sulfate-reducing bacteria, and Pseudomonadota (formerly proteobacteria). These microorganisms produce adhesive compounds that cement sand and other rocky materials to form mineral "microbial mats". In turn, these mats build up layer by layer, growing gradually over time. A stromatolite may grow to a meter or more. Although they are rare today, fossilized stromatolites provide records of ancient life on Earth. Morphology Stromatolites are layered, biochemical, accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains in biofilms (specifically microbial mats), through the action of certain microbial lifeforms, especially cyanobacteria. They exhibit a variety of forms and structures, or morphologies, including conical, stratiform, domal, columnar, and branching ...
