Black Rock Desert
The Black Rock Desert is a semi-arid region (in the Great Basin shrub steppe ecoregion) of lava beds and Dry lake, 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 (in the years 1971–2000) at Gerlach, Nevada, Gerlach (in the extreme south-west of the desert) is . The region is notable for its Paleogeology, paleogeologic features, as an area of 19th-century Emigrant Trails to California Trail, California, as a ...

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 rhyolite, rhyolitic and basaltic Volcanic cone, cones from near twenty-four volcanic vent, vents from which lava escapes through fault (geology), geologic faults.

Paleogeology
Historical geology or palaeogeology is a discipline that uses the principles and methods of geology to reconstruct the geological history of Earth. Historical geology examines the vastness of geologic time, measured in billions of years, and investigates changes in the Earth, gradual and sudden, over this deep time. It focuses on geological processes, such as plate tectonics, that have changed the Earth's surface and subsurface over time and the use of methods including stratigraphy, structural geology, paleontology, and sedimentology to tell the sequence of these events. It also focuses on the evolution of life during different time periods in the geologic time scale. Historical development During the 17th century, Nicolas Steno was the first to observe and propose a number of basic principles of historical geology, including three key stratigraphic principles: the law of superposition, the principle of original horizontality, and the principle of lateral continuity. 18 ...

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] |

The Bureau of Land Management (BLM) is an agency within the United States Department of the Interior responsible for administering federal lands, U.S. federal lands. Headquartered in Washington, D.C., the BLM oversees more than of land, or one-eighth of the United States's total landmass.

National Conservation Area
National Conservation Area is a designation for certain protected areas in the United States. They are nature conservation areas managed by the Bureau of Land Management (BLM) under the National Landscape Conservation System. Restrictions vary between these conservation areas, but generally they are not leased or sold under mining laws and motorized vehicle use is restricted, unlike many other BLM areas.

Burning Man
Burning Man is a week-long large-scale desert event focused on "community, art, self-expression, and self-reliance" held annually in the Western United States. The event's name comes from its ceremony on the penultimate night of the event: the symbolic burning of a large wooden effigy, referred to as the Man, the Saturday evening before Labor Day. Since 1990, the event has been at Black Rock City in northwestern Nevada, a temporary city erected in the Black Rock Desert about north-northeast of Reno, Nevada, Reno. According to Burning Man co-founder Larry Harvey in 2004, the event is guided by ten stated principles: radical inclusion, Gift Economy, gifting, decommodification, radical self-reliance, radical self-expression, communal effort, Civic engagement, civic responsibility, Leave no trace, leaving no trace, participation, and immediacy. Burning Man features no headliners or scheduled performers; participants create all the art, activities, and events. Artwork includes exper ...

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 piloted by Andy Green, when it achieved a speed of and it became the first and only land vehicle to officially break the sound barrier. Alongside Thrust2, Thrust SSC was displayed in the "Spirit of Speed Gallery" of the Coventry Transport Museum in Coventry, England. As part of the Museum's redevelopment project both cars were relocated by specialist haulier to the new Biffa Award Land Speed Record Gallery which opened in 2015. The car is long and wide and has a curb weight of 10.6 tons. It had a reported thrust of 223 kN (approximately 50,000 pounds force) at some operating conditions. Jet engines are not designed to operate at peak airspeed while still in ground effect; a proper estimate would need to take this into account. Details The jet was ...

Land Speed Record
The land speed record (LSR) or absolute land speed record is the highest speed achieved by a person using a vehicle on land. By a 1964 agreement between the Fédération Internationale de l'Automobile (FIA) and Fédération Internationale de Motocyclisme (FIM), respective governing bodies for racing in automobiles and motorcycles (two or three wheels), both bodies recognise as the absolute LSR whatever is the highest speed record achieved across any of their various categories. While the three-wheeled Spirit of America (automobile), ''Spirit of America'' set an FIM-validated LSR in 1963, all subsequent LSRs are by vehicles in FIA Category C ("Special Vehicles") in either class JE (jet engine) or class RT (rocket powered). FIA LSRs are officiated and validated by its regional or national affiliate organizations. Speed measurement is standardized over a course measuring either or , Arithmetic mean, averaged over two runs with flying start (commonly called "passes") going in oppo ...

Utah
Utah is a landlocked state in the Mountain states, Mountain West subregion of the Western United States. It is one of the Four Corners states, sharing a border with Arizona, Colorado, and New Mexico. It also borders Wyoming to the northeast, Idaho to the north, and Nevada to the west.

Bonneville Salt Flats
The Bonneville Salt Flats are a densely packed salt pan in Tooele County in northwestern Utah, United States. A remnant of the Pleistocene Lake Bonneville, it is the largest of many salt flats west of the Great Salt Lake. It is public land managed by the Bureau of Land Management and is known for land speed records at the Bonneville Speedway. The Flats is open to the public. The Flats are about 12 miles (19 km) long and 5 miles (8 km) wide, with a crust almost 5 ft (1.5m) thick at the center and less than one inch (2.5 cm) towards the edges. It is estimated to hold 147 million tons of salt, about 90% of which is common table salt. History Geologist Grove Karl Gilbert named the area after Benjamin Bonneville, a U.S. Army officer who explored the Intermountain West in the 1830s. In 1907, Bill Rishel and two local businessmen tested the suitability of the salt for driving by taking a Pierce-Arrow onto its surface. A railway line across the Flats was comp ...
