Santa Rosa Mountains (California)
The Santa Rosa Mountains are a short mountain range in the Peninsular Ranges system, located east of the Los Angeles Basin and northeast of the San Diego metropolitan area of southern California, in the southwestern United States. Geography The Santa Rosa Mountains extend for approximately along the western side of the Coachella Valley within Riverside, San Diego, and Imperial Counties in Southern California. The range connects to the San Jacinto Mountains on its northern end, where the Pines to Palms Highway—California State Route 74, crosses them. The highest peak in the range is Toro Peak (elevation ), located approximately south of Palm Springs, just south of Route 74, and on the northeast side of Anza-Borrego's Upper Coyote Canyon. The Santa Rosa Mountains are also a Great Basin Divide landform for the Salton Sink Watershed on the east. Besides Toro Peak, other significant mountains in the range include Santa Rosa Mountain, Martinez Mountain in the north and Rabbit Pe ...

Salton Sink
The Salton Sink is the low point of an endorheic basin, a closed drainage system with no outflows to other bodies of water, in the Colorado Desert sub-region of the Sonoran Desert. The sink falls within the larger Salton Trough and separates the Coachella Valley from the Imperial Valley, which are also segments of the Salton Trough. The lowest point of the sink is below sea level, and since 1906 the Salton Sea has filled the lowest portion of the sink to a water depth of up to . Geology The Salton Sink is the topographic low area within the Salton Trough, an active tectonic pull-apart basin. The Salton Trough is a result of crustal stretching and sinking by the combined actions of the San Andreas Fault and the East Pacific Rise. The Brawley seismic zone forms the southeast end of the basin and connects the San Andreas Fault system with the Imperial Fault Zone to the south. The Salton Buttes are rhyolite lava domes within the basin which were active 10,300 (± 1000) years BP. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaparral
Chaparral ( ) is a shrubland plant community and geographical feature found primarily in the U.S. state of California, in southern Oregon, and in the northern portion of the Baja California Peninsula in Mexico. It is shaped by a Mediterranean climate (mild wet winters and hot dry summers) and infrequent, high-intensity crown fires. Chaparral features summer-drought-tolerant plants with hard sclerophyllous evergreen leaves, as contrasted with the associated soft-leaved, drought-deciduous, scrub community of coastal sage scrub, found often on drier, southern facing slopes within the chaparral biome. Three other closely related chaparral shrubland systems occur in central Arizona, western Texas, and along the eastern side of central Mexico's mountain chains (mexical), all having summer rains in contrast to the Mediterranean climate of other chaparral formations. Chaparral comprises 9% of California's wildland vegetation and contains 20% of its plant species. The name comes from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecoregions
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Montane Chaparral And Woodlands
The California montane chaparral and woodlands is an ecoregion defined by the World Wildlife Fund, spanning of mountains in the Transverse Ranges, Peninsular Ranges, and Coast Ranges of southern and central California. The ecoregion is part of the larger California chaparral and woodlands ecoregion, and belongs to the Mediterranean forests, woodlands, and scrub biome. Geography The ecoregion spreads from low foothills up to the highest peaks of the following ranges: San Bernardino Mountains, San Jacinto Mountains, San Gabriel Mountains, Santa Susana Mountains, Santa Monica Mountains, Sierra Pelona, Topatopa Mountains, Tehachapi Mountains, San Rafael Mountains, Santa Ynez Mountains, and the long Santa Lucia Mountains. The wide elevation range and characteristic climate produce a variety of natural communities, from chaparral to mixed evergreen forest to alpine tundra.

Colorado Desert
California's Colorado Desert is a part of the larger Sonoran Desert. It encompasses approximately , including the heavily irrigated Coachella and Imperial valleys. It is home to many unique flora and fauna. Geography and geology The Colorado Desert is a subdivision of the larger Sonoran Desert encompassing approximately . The desert encompasses Imperial County and includes parts of San Diego County, Riverside County, and a small part of San Bernardino County, California, United States. Most of the Colorado Desert lies at a relatively low elevation, below , with the lowest point of the desert floor at below sea level, at the Salton Sea. Although the highest peaks of the Peninsular Ranges reach elevations of nearly , most of the region's mountains do not exceed . In this region, the geology is dominated by the transition of the tectonic plate boundary from rift to fault. The southernmost strands of the San Andreas Fault connect to the northernmost extensions of the East Pacif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USGS
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government.

Viceroyalty Of New Spain
New Spain, officially the Viceroyalty of New Spain ( es, Virreinato de Nueva España, ), or Kingdom of New Spain, was an integral territorial entity of the Spanish Empire, established by Habsburg Spain during the Spanish colonization of the Americas and having its capital in Mexico City. Its jurisdiction comprised a huge area that included what is now Mexico, the Western and Southwestern United States (from California to Louisiana and parts of Wyoming, but also Florida) in North America; Central America, the Caribbean, very northern parts of South America, and several territorial Pacific Ocean archipelagos. After the 1521 Spanish conquest of the Aztec empire, conqueror Hernán Cortés named the territory New Spain, and established the new capital, Mexico City, on the site of the Tenochtitlan, the capital of the Mexica (Aztec) Empire. Central Mexico became the base of expeditions of exploration and conquest, expanding the territory claimed by the Spanish Empire. With the politica ...

Las Californias
The Californias (Spanish: ''Las Californias''), occasionally known as The Three Californias or Two Californias, are a region of North America spanning the United States and Mexico, consisting of the U.S. state of California and the Mexican states of Baja California and Baja California Sur. Historically, the term ''Californias'' was used to define the vast northwestern region of Spanish America, as the ''Province of the Californias'' ( es, Provincia de las Californias), and later as a collective term for Alta California and the Baja California Peninsula. Originally a single, vast entity within the Spanish Empire, as the Californias became defined in their geographical limits, their administration was split various times into Baja California (''Lower California'') and Alta California (''Upper California''), especially during the Mexican control of the region, following the Mexican War of Independence. As a part of the Mexican–American War (1846–48), the American Conquest of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juan Bautista De Anza
Juan Bautista de Anza Bezerra Nieto (July 6 or 7, 1736 – December 19, 1788) was an expeditionary leader, military officer, and politician primarily in California and New Mexico under the Spanish Empire. He is credited as one of the founding fathers of Spanish California and served as an official within New Spain as Governor of the Province of New Mexico. Early life Juan Bautista de Anza Bezerra Nieto was born in Fronteras, New Navarre, New Spain (today Sonora, Mexico) in 1736 (near Arizpe), most probably at Cuquiarachi, Sonora, but possibly at the Presidio of Fronteras. His family was a part of the military leadership in Nueva España, as his father and maternal grandfather, Captain Antonio Bezerra Nieto, had both served Spain, their families living on the frontier of Nueva Navarre. He was the son of Juan Bautista de Anza I. It is traditionally thought that he may have been educated at the College of San Ildefonso in Mexico City, and later at the military academy there. In ...
