Pajarito Mountains, Arizona
The Pajarito Mountains is a small mountain range of western Santa Cruz County, Arizona, United States, that extend south into Sonora, Mexico. The range is adjacent the Atascosa Mountains at its north, with both ranges in the center of a north–south sequence of ranges called the Tumacacori Highlands. The Highlands have the Tumacacori Mountains at the north, and south of the U.S.-Mexico border, the Sierra La Esmeralda range (the Emerald Mountains). The Tumacacori Highlands are part of a regional conservancy study of "travel corridors" for cats, called ''Cuatro Gatos'', Four Cats, for mountain lions, ocelot, bobcat, and jaguar. The lower elevation Cerro Colorado Mountains to the northwest, and the San Luis Mountains, west are also part of the Highlands region. At the west of the Pajaritos and adjacent to the San Luis range, and Cobre Ridge peaks, is the Pajarita Wilderness. East of the Highlands is the Santa Cruz River Valley corridor.

Water Divide
A drainage divide, water divide, ridgeline, watershed, water parting or height of land is elevated terrain that separates neighboring drainage basins. On rugged land, the divide lies along topographical ridges, and may be in the form of a single range of hills or mountains, known as a dividing range. On flat terrain, especially where the ground is marshy, the divide may be difficult to discern. A triple divide is a point, often a summit, where three drainage basins meet. A ''valley floor divide'' is a low drainage divide that runs across a valley, sometimes created by deposition or stream capture. Major divides separating rivers that drain to different seas or oceans are continental divides. The term ''height of land'' is used in Canada and the United States to refer to a drainage divide. It is frequently used in border descriptions, which are set according to the "doctrine of natural boundaries". In glaciated areas it often refers to a low point on a divide where it is po ...

Sky Island
Sky islands are isolated mountains surrounded by radically different lowland environments. The term originally referred to those found on the Mexican Plateau and has extended to similarly isolated high-elevation forests. The isolation has significant implications for these natural habitats. Endemism, altitudinal migration, and relict populations are some of the natural phenomena to be found on sky islands. The complex dynamics of species richness on sky islands draws attention from the discipline of biogeography, and likewise the biodiversity is of concern to conservation biology. One of the key elements of a sky island is separation by physical distance from the other mountain ranges, resulting in a habitat island, such as a forest surrounded by desert. Some sky islands serve as refugia for boreal species stranded by warming climates since the last glacial period. In other cases, localized populations of plants and animals tend towards speciation, similar to oceanic isl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madrean Sky Islands
The Madrean Sky Islands are enclaves of Madrean pine–oak woodlands, found at higher elevations in a complex of small mountain ranges in southern and southeastern Arizona, southwestern New Mexico, and northwestern Mexico. The sky islands are surrounded at lower elevations by the Sonoran and Chihuahuan deserts. The northern west–east perimeter of the sky island region merges into the higher elevation eastern Mogollon Rim and the White Mountains of eastern Arizona (southern Anasazi region). The Sky Islands are the northernmost of the Madrean pine–oak woodlands, and are classified as part of the Sierra Madre Occidental pine–oak forests ecoregion, of the tropical and subtropical coniferous forests biome. The Sky Islands were isolated from one another and from the pine–oak woodlands of the Sierra Madre Occidental to the south by the warming and drying of the climate since the ice ages. There are approximately 27 Madrean Sky Islands in the United States, and 15 in norther ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ruby, Arizona
Ruby is a ghost town in Santa Cruz County, Arizona, United States. It was founded as a mining town in Bear Valley, originally named Montana Camp, so named because the miners were mining at the foot of Montana Peak. History Mining started ''circa'' 1877. The Montana Mine produced gold, silver, lead, zinc and copper. At its peak in the mid-1930s, Ruby had a population of about 1,200. On April 11, 1912 the mining camp's general store owner Julius Andrews established the post office. Andrews named the post office "Ruby", after his wife, Lille B. Ruby Andrews, and the mining camp soon became known as Ruby. The post office was discontinued on May 31, 1941. Between 1920 and 1922, the town of Ruby and the surroundings were the scene of three double homicides known as the Ruby Murders, which led to the largest manhunt in the history of the Southwest, which included the first airplane ever used in an Arizona manhunt. The most prosperous period for Ruby was in the late 1920s and 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ghost Town
A ghost town, deserted city, extinct town, or abandoned city is an abandoned settlement, usually one that contains substantial visible remaining buildings and infrastructure such as roads. A town often becomes a ghost town because the economic activity that supported it (usually industrial or agricultural) has failed or ended for any reason (e.g. a host ore deposit exhausted by mining). The town may have also declined because of natural or human-caused disasters such as floods, prolonged Drought, droughts, extreme heat or extreme cold, government actions, uncontrolled lawlessness, war, pollution, or nuclear and radiation accidents and incidents, nuclear and radiation-related accidents and incidents. The term can sometimes refer to cities, towns, and neighborhoods that, though still populated, are significantly less so than in past years; for example, those affected by high levels of unemployment and dereliction. Some ghost towns, especially those that preserve period-specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interstate 19
Interstate 19 (I-19) is a north–south Interstate Highway located entirely within the US state of Arizona. I-19 travels from Nogales, roughly from the Mexican border, to Tucson, at I-10. The highway also travels through the cities of Rio Rico, Green Valley, and Sahuarita. Having a total length of just over , I-19 is the eighth-shortest primary (two-digit) Interstate Highway in the contiguous 48 states, where only I-86 (Idaho), I-11 (Nevada), I-2 (Texas), I-42 (North Carolina), I-14 (Texas), I-97 (Maryland), and I-87 (North Carolina) are shorter. While the highway is short, it is a very important corridor, serving as a fast route from Tucson and Phoenix (via I-10) to the Mexican border. The highway is a portion of the US section of the CANAMEX Corridor, a trade corridor that stretches north from Mexico across the US to the Canadian province of British Columbia.
