Mazatzal Mountains
The Mazatzal Mountains (MAH-zaht-ZAL, locally Ma-tuh-ZEL) are a mountain range in south central Arizona, about 30–45 miles northeast of the Phoenix metropolitan area. The origin of the name remains obscure but one possibility is that it is from the Nahuatl language meaning "place of the deer". The crest of the Mazatzals forms the county line between Maricopa County and Gila County. SR 87, the Beeline Highway, traverses the Mazatzals on its way to Payson. The highest peak is Mazatzal Peak at . They also include the Four Peaks, with elevation 7,659 ft, 2,334 m; a prominent mountain and landmark of the eastern Phoenix area. The Mazatzal Wilderness Area protects of the Tonto and Coconino National forests. Established in 1940 and expanded to its present size in 1984, elevations range from at Sheep Bridge in the southwest to on Mazatzal Peak. The eastern side of the wilderness consists of brush- or pine-covered mountains, sometimes broken by narrow, vertical-walled canyon ...

Four Peaks, Mazatzal Mountains, Arizona
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other h ...

Arizona Transition Zone Mountain Ranges
Arizona ( ; nv, Hoozdo Hahoodzo ; ood, Alĭ ṣonak ) is a state in the Southwestern United States. It is the 6th largest and the 14th most populous of the 50 states. Its capital and largest city is Phoenix. Arizona is part of the Four Corners region with Utah to the north, Colorado to the northeast, and New Mexico to the east; its other neighboring states are Nevada to the northwest, California to the west and the Mexican states of Sonora and Baja California to the south and southwest. Arizona is the 48th state and last of the contiguous states to be admitted to the Union, achieving statehood on February 14, 1912. Historically part of the territory of in New Spain, it became part of independent Mexico in 1821. After being defeated in the Mexican–American War, Mexico ceded much of this territory to the United States in 1848. The southernmost portion of the state was acquired in 1853 through the Gadsden Purchase. Southern Arizona is known for its desert climate, with ve ...

Oak Creek Canyon
Oak Creek Canyon is a river gorge located in northern Arizona between the cities of Flagstaff and Sedona. The canyon is often described as a smaller cousin of the Grand Canyon because of its scenic beauty. State Route 89A enters the canyon on its north end via a series of hairpin turns before traversing the bottom of the canyon for about until the highway enters the town of Sedona. Geography Oak Creek Canyon is about long, ranging in width from . The depth of the canyon ranges from . However, due to the faulting that played a major role in its formation, the west rim of the canyon is higher than the east rim. The average elevation of the west rim is while the east rim elevation is . Oak Creek Oak Creek, a tributary of the Verde River, flows along the bottom of the canyon, and is one of the few perennial streams in the high desert region of northern Arizona. Oak Creek is largely responsible for carving the modern Oak Creek Canyon, although movement along the Oak Creek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mogollon Rim
The Mogollon Rim ( or or ) is a topographical and geological feature cutting across the northern half of the U.S. state of Arizona. It extends approximately , starting in northern Yavapai County and running eastward, ending near the border with New Mexico.The Mogollon Rim is not to be confused with the Mogollon Mountains in New Mexico located somewhat east of the eastern end of the Rim. The official estimate of the eastern end is near Show Low, AZ, Show Low, although some sources extend it farther east. See It forms the southern edge of the Colorado Plateau in Arizona. Description The Rim is an escarpment defining the southwestern edge of the Colorado Plateau. Its central and most spectacular portions are characterized by high cliffs of limestone and sandstone, namely the Kaibab Limestone and Coconino Sandstone cliffs. The escarpment was created by erosion and geologic fault, faulting, cutting dramatic canyons into it, including Fossil Creek Canyon and Pine Canyon. The na ...

Sierra Ancha
The Sierra Ancha ("broad range" in Spanish, in Western Apache: Dził Nteel - "Wide Flat Mountain") is a mountain range in Gila County, in central Arizona. It lies between Roosevelt Lake to the south, the Tonto Basin to the west, Cherry Creek to the east, and Pleasant Valley to the north. The range is one of several, including the Bradshaw Mountains, Mingus Mountain of the Black Hills, and the Mazatzal Mountains, which form a '' transitional zone'' between the lowland deserts of southern Arizona and the Colorado Plateau of northeastern Arizona. The highest point in the range is Aztec Peak, at an elevation of 2345 m (7694 ft). The Sierra Ancha is penetrated by few improved roads, and the range is cut by numerous deep, spectacular canyons, particularly on its eastern flank. Little agricultural, commercial, or residential development has taken place, though in the past asbestos mining was carried out at a mine between Asbestos and Zimmerman Points. Cattle ranching is still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vishnu Schist
The Vishnu Basement Rocks is the name recommended for all Early Proterozoic crystalline rocks (metamorphic and igneous) exposed in the Grand Canyon region. They form the crystalline basement rocks that underlie the Bass Limestone of the Unkar Group of the Grand Canyon Supergroup and the Tapeats Sandstone of the Tonto Group. These basement rocks have also been called either the Vishnu Complex or Vishnu Metamorphic Complex. These Early Proterozoic crystalline rocks consist of metamorphic rocks that are collectively known as the ''Granite Gorge Metamorphic Suite''; sections of the Vishnu Basement Rocks contain Early Paleoproterozoic granite, granitic pegmatite, aplite, and granodiorite that have intruded these metamorphic rocks, and also, intrusive Early Paleoproterozoic ultramafic rocks.Anonymous (nd''Vishnu Basement Rocks.''U.

Frenchman Mountain
Frenchman Mountain is a mountain located east of Las Vegas, Nevada. Made up of rocks similar to those found on the bottom of the Grand Canyon, Frenchman Mountain formed when Fault (geology), faulting elevated and tilted the rocks followed by erosion, giving it its sharp triangular profile. The mountain provides an example of the Great Unconformity with the tilted Paleozoic Tapeats Sandstone underlain by Paleoproterozoic Vishnu Schist, which is some of the oldest rock on the North American continent, having been created about two billion years ago. The peak lies on a north to north-northeast trending ridge about 2000 feet above the nearby valleys. Sunrise Mountain (Nevada), Sunrise Mountain lies to the northeast adjacent to Nellis Air Force Base. The north end of the McCullough Range about to the south has a parallel trend. The River Mountains lie to the southeast. Nevada State Route 147, State Route 147 crosses its northern slope. A geologically rich area called Rainbow Garde ...

Las Vegas Valley (landform)
The Las Vegas Valley is a major metropolitan area in the southern part of the U.S. state of Nevada, and the second largest in the Southwestern United States. The state's largest urban agglomeration, the Las Vegas Metropolitan Statistical Area is coextensive since 2003 with Clark County, Nevada. The Valley is largely defined by the Las Vegas Valley landform, a basin area surrounded by mountains to the north, south, east and west of the metropolitan area. The Valley is home to the three largest incorporated cities in Nevada: Las Vegas, Henderson and North Las Vegas. Eleven unincorporated towns governed by the Clark County government are part of the Las Vegas Township and constitute the largest community in the state of Nevada. The names Las Vegas and Vegas are interchangeably used to indicate the Valley, the Strip, and the city, and as a brand by the Las Vegas Convention and Visitors Authority to denominate the region. The Valley is affectionately known as the "ninth island" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Unconformity
Of the many unconformities (gaps) observed in geological strata, the term Great Unconformity is frequently applied to either the unconformity observed by James Hutton in 1787 at Siccar Point in Scotland,Rance, H (1999''Historical Geology: The Present is the Key to the Past.'' QCC Press, New York or that observed by John Wesley Powell in the Grand Canyon in 1869. Both instances are exceptional examples of where the contacts between sedimentary strata and either sedimentary or crystalline strata of greatly different ages, origins, and structure represent periods of geologic time sufficiently long to raise great mountains and then erode them away. Background Unconformities tend to reflect long-term changes in the pattern of the accumulation of sedimentary or igneous strata in low-lying areas (often ocean basins, such as the Gulf of Mexico or the North Sea, but also Bangladesh and much of Brazil), then being uplifted and eroded (such as the ongoing Himalayan orogeny, the older Larami ...

Zoroaster,; fa, زرتشت, Zartosht, label= Modern Persian; ku, زەردەشت, Zerdeşt also known as Zarathustra,, . Also known as Zarathushtra Spitama, or Ashu Zarathushtra is regarded as the spiritual founder of Zoroastrianism. He is said to have been an Iranian prophet who founded a religious movement that challenged the existing traditions of ancient Iranian religion, and inaugurated a movement that eventually became a staple religion in ancient Iran. He was a native speaker of Old Avestan and lived in the eastern part of the Iranian plateau, but his exact birthplace is uncertain. There is no scholarly consensus on when he lived. Some scholars, using linguistic and socio-cultural evidence, suggest a dating to somewhere in the second millennium BC. Other scholars date him to the 7th and 6th centuries BC as a near-contemporary of Cyrus the Great and Darius the Great. Zoroastrianism eventually became the official state religion of ancient Iran—particularly during th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
