Sierra La Esmeralda
The Sierra La Esmeralda range, (Emerald Mountains) are a mountain range in northern Sonora, Mexico at the northern region of the Sierra Madre Occidental cordillera. The region contains sky island mountain ranges, called the Madrean Sky Islands, some separated from the Sierra Madre Occidental proper, and occurring in the northeastern Sonoran Desert, and extreme west-northwestern Chihuahuan Desert. Many of the ranges occur in southeast Arizona. Sierra La Esmeralda anchors the southern portion of the ''Tumacacori Highlands''. The range is part of a Sky Island Alliance study of wild cats, called ''Cuatros Gatos'', (Four Cats).Arizona Highways Magazine, ''Emerald Isle'', pp. 40–43. Nogales, Arizona and Nogales, Sonora lie at the northeast of the range. Tumacacori Highlands The Tumacacori Highlands is a series of connected mountain ranges in western Santa Cruz County, Arizona. The Highlands are northwest of Nogales and are bordered on the east by the '' Santa Cruz River Valley'', ...

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 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 ...

Madrean Sky Islands Mountain Ranges
The Madrean Region (named after the Sierra Madre Occidental) is a floristic region within the Holarctic Kingdom in North America, as delineated by Armen Takhtajan and Robert F. Thorne. It occupies arid or semiarid areas in the southwestern United States and northwestern Mexico and is bordered by the Rocky Mountain Region and North American Atlantic Region of the Holarctic Kingdom in the north and in the east, Caribbean Region of the Neotropical Kingdom in the south. The Madrean Region is characterized by a very distinct flora with at least three endemic families ( Fouquieriaceae, Simmondsiaceae, and Setchellanthaceae). Crossosomataceae, Garryaceae, Lennoaceae, Limnanthaceae and Stegnospermataceae have their principal development here; for Onagraceae, Polemoniaceae and Hydrophyllaceae it is the major center of diversity. More than 250 genera and probably more than half of the species of the region are endemic to it according to Takhtajan. Floristic provinces The region is s ...

Landforms Of The Sierra Madre Occidental
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Arizona Highways
''Arizona Highways'' is a magazine that contains travelogues and artistic photographs related to the U.S. state of Arizona. It is published monthly in Phoenix by a unit of the Arizona Department of Transportation (ADOT). Background The magazine began in July 1921 by the Arizona Highway Department (now the Arizona Department of Transportation) as a 10-page pamphlet designed to promote "the development of good roads throughout the state." Publication of the pamphlet ended on December 30, 1922, after nine issues. The publication was relaunched on April 15, 1925, as a regular magazine. In addition to the engineering articles, cartoons and travelogues were also included in the early issues. Over the next two decades the magazine reduced, and then stopped, inclusion of the road engineering articles and dedicated itself to the present format of travel tales, historical stories, and humor about the state of Arizona (including stories about Arizona's contribution to the history of ...

Tumacacori, Arizona
Tumacacori (; ood, Cemagĭ Gakolig) is an unincorporated community in Santa Cruz County, Arizona, United States, which abuts the community of Carmen. Together, the communities constitute the Tumacacori-Carmen census-designated place (CDP). The population of the CDP was 393 at the 2010 census. History Tumacacori is the site of Mission San José de Tumacácori, a Franciscan mission that was built in the late 18th century. It takes its name from an earlier mission site founded by Father Eusebio Kino in 1691, which is on the east side of the Santa Cruz River, south of the national park. This Kino-period mission was founded at an extant native O'odham or Sobaipuri settlement and represents the first mission in southern Arizona, but not the first mission in Arizona. The remains of the native settlement are still extant and have been investigated and reported on by archaeologist Deni Seymour. The later Franciscan mission, which is now a ruin preserved as Tumacácori National Histor ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Buenos Aires National Wildlife Refuge
Buenos Aires National Wildlife Refuge (Buenos Aires NWR) provides of habitat for threatened and endangered plants and animals. This refuge, in Pima County, Arizona, was established in 1985. Natural history The semidesert grassland supports the reintroduction of Masked quail and pronghorns. Prescribed and natural fires play a major role in maintaining and restoring the sea of grass that once filled the Altar Valley. Riparian (wetland) areas along Arivaca Cienega and Arivaca Creek attract an abundance of birds. Brown Canyon, to the west of the Arivaca Creek area, is nestled in the Baboquivari Mountains, where a sycamore-lined stream meanders through oak woodland. Fauna The refuge is home to 58 mammal species. Among the larger species are mule deer, white-tailed deer, pronghorn, javelina and puma. There are also more than 325 different bird species and 53 species of reptiles and amphibians. Reintroduced masked bobwhite (''Colinus virginianus ridgwayi'') are found in the refuge. ...

Altar Valley
The Altar Valley is a 45-mile (72 km) long north–south valley, trending slightly northeast from Sasabe, Arizona on the Mexico border to the Avra Valley west of the Tucson Mountains. It is delimited by Arizona State Route 86, from east-to-west on the north separating it from the Avra Valley which then trends ''northwesterly'', merging into the plains and drainage of the Santa Cruz River. The valley is traversed from north to south by Arizona Route 286. The major Baboquivari sky island range borders the valley on the west; the east is bordered by a series of mountain ranges, that have Nogales, Arizona nestled in between at the United States-Mexico border. Two wilderness areas lie to the west of the valley, the Coyote Mountains Wilderness east of Kitt Peak Observatory, and the Baboquivari Peak Wilderness. The center of the valley is near Baldy Peak in the southwest Sierrita Mountains. Baldy Peak's height is .Arizona Road & Recreation Atlas, pp. 86–87. Madrean Sky Isl ...
