Arizona Transition Zone
The Arizona transition zone is a diagonal northwest-by-southeast region across central Arizona. The region is a transition from the higher-elevation Colorado Plateau in Northeast Arizona and the Basin and Range region of lower-elevation deserts in the southwest and south. Northwest Arizona transitions to the lower elevation Mojave Desert of southern California, Nevada and Utah, with an indicator species of Joshua trees and other species, and southwestwards regions of the Sonoran Desert, along the Lower Colorado River Valley; in Arizona's south, all of central and eastern desert Sonoran Desert regions merge southwards into Sonora Mexico. The transition zone includes the Mogollon Rim and the White Mountains and extends into western New Mexico. In the Arizona ecoregion section, the Arizona transition zone is the major section of the EPA designated, Level III ecoregion, ''Arizona/New Mexico Mountains ecoregion''. The other two outlier subregions to the transition zone in Arizona, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountain Ranges Of Yavapai 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 ...

Massif
In geology, a massif ( or ) is a section of a planet's crust that is demarcated by faults or flexures. In the movement of the crust, a massif tends to retain its internal structure while being displaced as a whole. The term also refers to a group of mountains formed by such a structure. In mountaineering and climbing literature, a massif is frequently used to denote the main mass of an individual mountain. The massif is a smaller structural unit of the crust than a tectonic plate, and is considered the fourth-largest driving force in geomorphology. The word is taken from French (in which the word also means "massive"), where it is used to refer a large mountain mass or compact group of connected mountains forming an independent portion of a range. One of the most notable European examples of a massif is the Massif Central of the Auvergne region of France. The Face on Mars is an example of an extraterrestrial massif. Massifs may also form underwater, as with the Atlanti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arizona State Route 89
State Route 89 (SR 89) is a state highway in the U.S. state of Arizona. It is part of the former route of U.S. Route 89 (US 89) throughout the state. Route description The southern terminus of SR 89 is located at an intersection with U.S. Route 93 northwest of Wickenburg. It is a largely south-north route; the largest city through which it now passes is Prescott, where it meets SR 69 and the extremely scenic SR 89A. The segment between Prescott and Congress (intersection with SR 71) is quite scenic. The northern terminus of the highway is located at an interchange with Interstate 40 (I-40) in Ash Fork. History This highway was a segment of US 89 between Ash Fork at I-40 and US 93 northwest of Wickenburg. All of US 89 was deleted south of its current southern terminus with Interstate 40 in Flagstaff after interstate highways offered shorter and more direct routes than the old long-distance US 89 in central and southern A ...

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 ...

Granite Mountain (Arizona)
Granite Mountain ( yuf-x-yav, ʼWi:kvte:wa) is a mountain located in Yavapai County, Arizona that covers roughly 12 square miles (31 km2). It was once known as Mount Gurley, for the first governor of the Arizona Territory, John A. Gurley. Its southwest face has a sheer granite cliff approximately 500 feet (150 m) high that is one of the best locations for rock climbing in the state of Arizona. It is located in the Granite Mountain Wilderness, which is managed as a part of the Prescott National Forest. The mountain stands at the northern end of the Sierra Prietas, and borders Skull Valley on the west, on the northwest by the Santa Maria Mountains, and east by the Williamson Valley. Geology Granite Mountain is composed of Paleoproterozoic biotite granodiorite to granite that is known by geologist as the Mint Wash Granodiorite.DeWitt, E., Langenheim, V., Force, E., Vance, R.K., Lindberg, P.A., and Driscoll, R.L., 2008.

Volcanic Plug
A volcanic plug, also called a volcanic neck or lava neck, is a volcanic object created when magma hardens within a vent on an active volcano. When present, a plug can cause an extreme build-up of high gas pressure if rising volatile-charged magma is trapped beneath it, and this can sometimes lead to an explosive eruption. In a plinian eruption the plug is destroyed and ash is ejected. Glacial erosion can lead to exposure of the plug on one side, while a long slope of material remains on the opposite side. Such landforms are called crag and tail. If a plug is preserved, erosion may remove the surrounding rock while the erosion-resistant plug remains, producing a distinctive upstanding landform. Examples of volcanic plugs Africa Near the village of Rhumsiki in the Far North Province of Cameroon, Kapsiki Peak is an example of a volcanic plug and is one of the most photographed parts of the Mandara Mountains. Spectacular volcanic plugs are present in the center of La Gomer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types. Major ranges Most geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bradshaw Mountains
The Bradshaw Mountains ( yuf-x-yav, Wi:kañacha, "rough, black range of rocks") are a mountain range in central Arizona, United States, named for brothers Isaac and William D. Bradshaw after their deaths, having been formerly known in English as the Silver Mountain Range. History The first known settlements in the Bradshaws were a group of Yavapai people, called the Kwevkapaya who built forts and mined copper from around AD 1100 to 1600. The Walker party found gold, and within a few years, the Bradshaws were filling up with settlers mining for gold, silver, and copper. In the early part of the 20th century, most of the towns that had sprung up were little more than ghost towns. Geography Located approximately 5 miles (8 km) south of Prescott, Arizona, between the Agua Fria River on the east, and the Hassayampa River on the west, the range is 40 miles (64 km) long, and almost 25 miles (40 km) wide.
