Black Rock Desert
__NOTOC__ The Black Rock Desert is a semi-arid region (in the Great Basin shrub steppe eco-region) of lava beds and playa, or alkali flats, situated in the Black Rock Desert–High Rock Canyon Emigrant Trails National Conservation Area, a silt playa north of Reno, Nevada that encompasses more than of land and contains more than of historic trails. It is in the northern Nevada section of the Great Basin with a lakebed that is a dry remnant of Pleistocene Lake Lahontan. The Great Basin, named for the geography in which water is unable to flow out and remains in the basin, is a rugged land serrated by hundreds of mountain ranges, dried by wind and sun, with spectacular skies and scenic landscapes. The average annual precipitation ''(years 1971-2000)'' at Gerlach, Nevada (extreme south-west of the desert) is . The region is notable for its paleogeologic features, as an area of 19th-century Emigrant Trails to California, as a venue for rocketry, and as an alternative to the ...

Black Rock Desert Volcanic Field
The Black Rock Desert volcanic field in Millard County, Utah, is a cluster of several volcanic features of the Great Basin including Pahvant Butte, The Cinders, and Tabernacle Hill. The field's Ice Springs event was an explosive eruption followed by lava flows that were Utah's most recent volcanic activity (1140–1440 AD). which overlapped the older flows of Pavant Butte. The Pleistocene-Holocene field has been an active tectonic area for approximately 2.7 million years. Within the past 1.5 million years, local volcanism has produced both rhyolitic and basaltic cones from near twenty-four vents from which lava Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or un ... escapes through geologic faults. References Sources * * * * * * * * * * * * * * * * * * * ...

Emigrant Trail
In the history of the American frontier, overland trails were built by pioneers throughout the 19th century and especially between 1829 and 1870 as an alternative to sea and railroad transport. These immigrants began to settle much of North America west of the Great Plains as part of the mass overland migrations of the mid-19th century. Settlers emigrating from the eastern United States were spurred by various motives, among them religious persecution and economic incentives, to move to destinations in the far west via routes including the Oregon Trail, California Trail, and Mormon Trail. After the end of the Mexican–American War in 1849, vast new American conquests again enticed mass immigration. Legislation like the Donation Land Claim Act and significant events like the California Gold Rush further lured people to travel overland to the west. Two major wagon-based transportation networks, one typically starting in Missouri and the other in the Mexican province of Santa ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permian
The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids ( reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of their am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jack Lee Harelson
Jack Lee Harelson (1940 - December 14, 2012) was an American insurance agent, best known for desecrating and looting a Paiute Indian burial site in the Black Rock Desert of Nevada. Biography Jack Lee Harelson was an insurance agent in Grants Pass, Oregon. In 1995, one of his former business partners in an opal mine tipped off police that Harelson had been looting Amerindian sites. In exchange for immunity from prosecution, Harelson's ex-wife Pamela Ralph led police investigators to an Elephant Mountain Cave in the Black Rock Desert in Nevada. She stated that she and Harelson had dug and collected American Indian treasures in the early 1980s. She had photographs of the cave that had significantly grown after three years of digging. Harelson had built a wall to hide a dirt pile. Digging had totally destroyed the site, which had included various artifacts, including those from the Paiute tribe. Oregon State Police recovered over 2,000 artifacts from Harelson's home in Grants Pass, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bureau Of Land Management
The Bureau of Land Management (BLM) is an agency within the United States Department of the Interior responsible for administering federal lands. Headquartered in Washington DC, and with oversight over , it governs one eighth of the country's landmass. President Harry S. Truman created the BLM in 1946 by combining two existing agencies: the General Land Office and the Grazing Service. The agency manages the federal government's nearly of subsurface mineral estate located beneath federal, state and private lands severed from their surface rights by the Homestead Act of 1862. Most BLM public lands are located in these 12 western states: Alaska, Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming. The mission of the BLM is "to sustain the health, diversity, and productivity of the public lands for the use and enjoyment of present and future generations." Originally BLM holdings were described as "land nobody wanted" because home ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Burning Man
Burning Man is an event focused on community, art, self-expression, and self-reliance held annually in the western United States. The name of the event comes from its culminating ceremony: the symbolic burning of a large wooden effigy, referred to as the Man, that occurs on the penultimate night of Burning Man, which is the Saturday evening before Labor Day. The event has been located since 1991 at Black Rock City in northwestern Nevada, a temporary city erected in the Black Rock Desert about north-northeast of Reno. As outlined by Burning Man co-founder Larry Harvey in 2004, the event is guided by ten principles: radical inclusion, gifting, decommodification, radical self-reliance, radical self-expression, communal effort, civic responsibility, leaving no trace, participation, and immediacy. The event originated on June 22, 1986, on Baker Beach in San Francisco as a small function organized by Larry Harvey and Jerry James, the builders of the first Man. It has since bee ...

ThrustSSC
ThrustSSC, Thrust SSC or Thrust SuperSonic Car is a British jet car developed by Richard Noble, Glynne Bowsher, Ron Ayers, and Jeremy Bliss. Thrust SSC holds the world land speed record, set on 15 October 1997, and driven by Andy Green, when it achieved a speed of and became the first land vehicle to officially break the sound barrier. Both Thrust SSC and Thrust2 are displayed at the Coventry Transport Museum in Coventry, England. As part of the Museum's redevelopment project, both cars were relocated by specialist haulier from their position in the Museum's Spirit of Speed Gallery to the new Biffa Award Land Speed Record Gallery which opened in 2015. The car is long and wide and weighs nearly 10 tons. It had a reported thrust of 223 kN (approximately 50,000 pounds force) at some operating condition. If achieving full reported thrust while operating at the record speed, it works out to around 102,000 brake horsepower, calculated as force times velocity. Jet engine ...

Land Speed Record
The land speed record (or absolute land speed record) is the highest speed achieved by a person using a vehicle on land. There is no single body for validation and regulation; in practice the Category C ("Special Vehicles") flying start regulations are used, officiated by regional or national organizations under the auspices of the Fédération Internationale de l'Automobile (FIA). The land speed record (LSR) is standardized as the speed over a course of fixed length, averaged over two runs (commonly called "passes"). Two runs are required in opposite directions within one hour, and a new record mark must exceed the previous one by at least one percent to be validated. History The first regulator was the ''Automobile Club de France'', which proclaimed itself arbiter of the record in about 1902. Until 1903, trains held the land speed record for fastest vehicles in which people could travel. Different clubs had different standards and did not always recognize the same wor ...
