West Silver Bell Mountains
The West Silver Bell Mountains are a small 10 mile (16 km) long mountain range of south-central Arizona, United States. The range lies in the north-central arid Sonoran Desert; the Madrean Sky Islands region of southeast Arizona, around Tucson is adjacent to the southeast. The range lies mostly in Pima County with only the northernmost end extending into southern Pinal County The range lies 25 mi west of Marana, and 25 mi south of Eloy–Casa Grande, all cities on Interstate 10 in Arizona. Casa Grande also begins the west route of Interstate 8 to Yuma and San Diego. Description The West Silver Bell Mountains are a small, low elevation range, in eastern regions of Arizona's Sonoran Desert. Lower elevation regions west or southwest are even more arid, as the Sonoran Desert gets closer to the Gran Desierto de Altar in northwestern Mexico. The West Silver Bell Mountains are northwest–southeast trending, and merge in the southeast with the Silver Bell M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sonoran Desert
The Sonoran Desert ( es, Desierto de Sonora) is a desert in North America and ecoregion that covers the northwestern Mexican states of Sonora, Baja California, and Baja California Sur, as well as part of the southwestern United States (in Arizona and California). It is the hottest desert in both Mexico and the United States. It has an area of . In phytogeography, the Sonoran Desert is within the Sonoran Floristic province of the Madrean Region of southwestern North America, part of the Holarctic realm of the northern Western Hemisphere. The desert contains a variety of unique endemic plants and animals, notably, the saguaro (''Carnegiea gigantea'') and organ pipe cactus (''Stenocereus thurberi''). The Sonoran Desert is clearly distinct from nearby deserts (e.g., the Great Basin, Mojave, and Chihuahuan deserts) because it provides subtropical warmth in winter and two seasons of rainfall (in contrast, for example, to the Mojave's dry summers and cold winters). This creates an ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountain Ranges Of Pima 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 Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosystems of mountains: different elevations have different plants and ...

Ironwood Forest National Monument
Ironwood Forest National Monument is located in the Sonoran Desert of Arizona. Created by Bill Clinton by Presidential Proclamation 7320 on June 9, 2000, the monument is managed by the Bureau of Land Management, an agency within the United States Department of the Interior. The monument covers , of which are non-federal and include private land holdings and Arizona State School Trust lands. A significant concentration of ironwood (also known as desert ironwood, ''Olneya tesota'') trees is found in the monument, along with two federally recognized endangered animal and plant species. More than 200 Hohokam archaeological sites have been identified in the monument, dated between 600 and 1450. Flora and fauna Flora An array of flora are present in the Ironwood Forest National Monument. The lower elevations are in the Sonoran Desert ecoregion. One of the notable trees native here is the elephant tree (''Bursera microphylla'').C. Michael Hogan. 2009''Elephant Tree: Bursera micro ...

Gila River
The Gila River (; O'odham ima Keli Akimel or simply Akimel, Quechan: Haa Siʼil, Maricopa language: Xiil) is a tributary of the Colorado River flowing through New Mexico and Arizona in the United States. The river drains an arid watershed of nearly that lies mainly within the U.S., but also extends into northern Sonora, Mexico. Indigenous peoples have lived along the river for at least 2,000 years, establishing complex agricultural societies before European exploration of the region began in the 16th century. However, European Americans did not permanently settle the Gila River watershed until the mid-19th century. During the 20th century, human development of the Gila River watershed prompted the construction of large diversion and flood control structures on the river and its tributaries, and consequently the Gila now contributes only a small fraction of its historic flow to the Colorado. The historic natural discharge of the river is around , and is now only . These engin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Cruz River (Arizona)
The Santa Cruz River ( es, Río Santa Cruz " Holy Cross River") is a tributary river to the Gila River in Southern Arizona and northern Sonora, Mexico. It is approximately long. Course The Santa Cruz has its headwaters in the high intermontane grasslands of the San Rafael Valley to the southeast of Patagonia, Arizona, between the Canelo Hills to the east and the Patagonia Mountains to the west, just north of the international border. It flows southward into Mexico past Santa Cruz, Sonora and turns westward around the south end of the Sierra San Antonio near Miguel Hidalgo (San Lázaro), thence north-northwest to reenter the United States just to the east of Nogales and southwest of Kino Springs. It then continues northward from the international border past the Tumacacori National Historical Park, Tubac, Green Valley, Sahuarita, San Xavier del Bac, Tucson, Marana, and Picacho Peak State Park to the Santa Cruz Flats just to the south of Casa Grande and the Gila River.

Basin And Range Province
The Basin and Range Province is a vast physiographic region covering much of the inland Western United States and northwestern Mexico. It is defined by unique basin and range topography, characterized by abrupt changes in elevation, alternating between narrow faulted mountain chains and flat arid valleys or basins. The physiography of the province is the result of tectonic extension that began around 17 million years ago in the early Miocene epoch. The numerous ranges within the province in the United States are collectively referred to as the "Great Basin Ranges", although many are not actually in the Great Basin. Major ranges include the Snake Range, the Panamint Range, the White Mountains, and the Sandia Mountains. The highest point fully within the province is White Mountain Peak in California, while the lowest point is the Badwater Basin in Death Valley at . The province's climate is arid, with numerous ecoregions. Most North American deserts are located within it. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Slate Mountains
Slate is a fine-grained, foliation (geology), foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcano, volcanic ash (volcanic), ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate is called "slaty cleavage". It is caused by strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression. When expertly "cut" by striking parallel to the foliation, with a specialized tool in the quarry, many slates will display a property called fissility (geology), fissility, forming smooth flat sheets of stone which have long been used for roofing, floor tiles, and other purposes. Slate is frequently grey in color, especially when seen, en masse, covering roofs. However, slate o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
