Lukachukai Mountains
The Lukachukai Mountains are a mountain range in northeast Arizona, entirely located on the Navajo Nation. The highest point of the range is an unnamed point at above sea level. While open during the winter, no road maintenance is performed and chains or four wheel drive with good snow tires are essential due to grades of up to 14% in many places. The Lukachukai Mountain trail gives access to some of the scenic red-rock high country here. The trailhead is located just south of Buffalo Pass on Indian Route 13, a paved highway. The trail is passable to OHVs in dry weather. A permit is required from the Navajo Nation government. There is a belt of uranium deposits that crosses the Lukachukai Mountains. The ore belt is within a bed of lenticular sandstone and mudstone that apparently provided sufficient permeable sandstone for the passage of ore solutions, and sufficient impermeable mudstone to restrict movement of solutions to particular sandstone beds. An unusual concentration ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Navajo Nation
The Navajo Nation ( nv, Naabeehó Bináhásdzo), also known as Navajoland, is a Native Americans in the United States, Native American Indian reservation, reservation in the United States. It occupies portions of northeastern Arizona, northwestern New Mexico, and southeastern Utah; at roughly , the Navajo Nation is the largest land area held by a Native American tribe in the U.S., exceeding List of U.S. states and territories by area, ten U.S. states. In 2010, the reservation was home to 173,667 out of 332,129 Navajo tribal members; the remaining 158,462 tribal members lived outside the reservation, in urban areas (26 percent), border towns (10 percent), and elsewhere in the U.S. (17 percent). The seat of government is located in Window Rock, Arizona. The United States gained ownership of this territory in 1848 after acquiring it in the Mexican-American War. The reservation was within New Mexico Territory and straddled what became the Arizona-New Mexico border in 1912, when th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Off Highway Vehicle
An off-road vehicle, sometimes referred to as an overland or adventure vehicle, is considered to be any type of vehicle which is capable of driving on and off paved or gravel surface. It is generally characterized by having large tires with deep, open treads, a flexible suspension, or even caterpillar tracks. Other vehicles that do not travel on public streets or highways are generally termed off-highway vehicles, including tractors, forklifts, cranes, backhoes, bulldozers, and golf carts. Off-road vehicles have an enthusiastic following because of their versatility. Several types of motorsports involve racing off-road vehicles. The most common use of these vehicles is for sightseeing in areas distant from the pavement. The use of higher clearance and higher traction vehicles enables access on trails and forest roads that have rough and low traction surfaces. Off-road vehicles can typically ford through deeper waters (i.e., rivers or floodwaters) than on-road vehicles can. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium Deposits
Uranium ore deposits are economically recoverable concentrations of uranium within the Earth's crust. Uranium is one of the more common elements in the Earth's crust, being 40 times more common than silver and 500 times more common than gold. It can be found almost everywhere in rock, soil, rivers, and oceans. The challenge for commercial uranium extraction is to find those areas where the concentrations are adequate to form an economically viable deposit. The primary use for uranium obtained from mining is in fuel for nuclear reactors. Globally, the distribution of uranium ore deposits is widespread on all continents, with the largest deposits found in Australia, Kazakhstan, and Canada. To date, high-grade deposits are only found in the Athabasca Basin region of Canada. Uranium deposits are generally classified based on host rocks, structural setting, and mineralogy of the deposit. The most widely used classification scheme was developed by the International Atomic Energy Agen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mudstone
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from ''shale'' by its lack of fissility (parallel layering).Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York, W. H. Freeman, 2nd ed, 529 pp. The term ''mudstone'' is also used to describe carbonate rocks ( limestone or dolomite) that are composed predominantly of carbonate mud. However, in most contexts, the term refers to siliciclastic mudstone, composed mostly of silicate minerals. The NASA Curiosity rover has found deposits of mudstone on Mars that contain organic substances such as propane, benzene and toluene. Definition There is not a single definition of mudstone that has gained general acceptance,Boggs 2006, p.143 though there is wide agreement that mudstones are fine-grained sedimentary rocks, composed mostly of silicate grains with a grain size less than . Individual grains this size are too small to be distin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tony Hillerman
Anthony Grove Hillerman (May 27, 1925 – October 26, 2008) was an American author of detective novels and nonfiction works, best known for his mystery novels featuring Navajo Nation Police officers Joe Leaphorn and Jim Chee. Several of his works have been adapted as theatrical and television movies. Biography Tony Hillerman was born in Sacred Heart, Oklahoma, to August Alfred Hillerman, a farmer and shopkeeper, and his wife, Lucy Grove. He was the youngest of their three children, and the second son. His paternal grandparents were born in Germany, and his maternal grandparents were born in England. He grew up in Pottawatomie County, Oklahoma, attending elementary and high school with Potawatomi children. Jeffrey Herlihy argues that this background made possible "a significantly different portrayal of Native Americans in his writing", in comparison to other authors of his time. "Growing up Indian," Hillerman said of his childhood, "you did not have an 'us and them.'" He wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountain Ranges Of Apache County, Arizona
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Geography Of The Navajo Nation
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
