Llano Estacado
The Llano Estacado (), sometimes translated into English as the Staked Plains, is a region in the Southwestern United States that encompasses parts of eastern New Mexico and northwestern Texas. One of the largest mesas or tablelands on the North American continent, the elevation rises from in the southeast to over in the northwest, sloping almost uniformly at about . Naming The Spanish name is often interpreted as meaning "Staked Plains", although " stockaded" or " palisaded plains" have also been proposed, in which case the name would derive from the steep escarpments on the eastern, northern, and western periphery of the plains. Leatherwood writes that Francisco Coronado and other European explorers described the Mescalero Ridge on the western boundary as resembling "palisades, ramparts, or stockades" of a fort, but does not present the original Spanish. In ''Beyond the Mississippi'' (1867), Albert D. Richardson, who traversed the region from east to west in October 1859 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caprock Escarpment
The Caprock Escarpment is a term used in West Texas and Eastern New Mexico to describe the geographical transition point between the level High Plains of the Llano Estacado and the surrounding rolling terrain. In Texas, the escarpment stretches around south-southwest from the northeast corner of the Texas Panhandle near the Oklahoma border. The escarpment is especially notable, from north to south, in Briscoe, Floyd, Motley, Crosby, Dickens, Garza, and Borden Counties. In New Mexico, a prominent escarpment exists along the northernmost extension of the Llano Estacado, especially to the south of San Jon and Tucumcari, both in Quay County, New Mexico. Along the western edge of the Llano Estacado, the portion of the escarpment that stretches from Caprock to Maljamar, New Mexico, is called the Mescalero Ridge. Description The escarpment is made of caliche—a layer of calcium carbonate that resists erosion. In some places, the escarpment rises around above the plains ...

Dust Storms
A dust storm, also called a sandstorm, is a meteorological phenomenon common in arid and semi-arid regions. Dust storms arise when a gust front or other strong wind blows loose sand and dirt from a dry surface. Fine particles are transported by saltation and suspension, a process that moves soil from one place and deposits it in another. The arid regions of North Africa, the Arabian peninsula, Central Asia and China are the main terrestrial sources of airborne dust. It has been argued that poor management of Earth's drylands, such as neglecting the fallow system, are increasing the size and frequency of dust storms from desert margins and changing both the local and global climate, as well as impacting local economies. The term ''sandstorm'' is used most often in the context of desert dust storms, especially in the Sahara Desert, or places where sand is a more prevalent soil type than dirt or rock, when, in addition to fine particles obscuring visibility, a co ...

Texas Counties
The U.S. state of Texas is divided into 254 counties, more than any other U.S. state. Over 20% of Texas counties are generally located within the Houston-Dallas—San Antonio—Austin areas, serving about 20,000,000 people, the majority of the state's population. Texas was originally divided into municipalities (''municipios'' in Spanish), a unit of local government under Spanish and Mexican rule. When the Republic of Texas gained its independence in 1836, the 23 municipalities became the original Texas counties. Many of these were later divided into new counties. The last county to be initially created was Kenedy County in 1921, but Loving County is the newest organized county; it was first organized in 1893 in an apparent scheme to defraud, abolished in 1897, then reorganized in 1931. Most of these recent counties, especially near the northwest, were created from Bexar County during the 1870s. Each county is run by a commissioners' court, consisting of four elected comm ...

Indiana
Indiana () is a U.S. state in the Midwestern United States. It is the 38th-largest by area and the 17th-most populous of the 50 States. Its capital and largest city is Indianapolis. Indiana was admitted to the United States as the 19th state on December 11, 1816. It is bordered by Lake Michigan to the northwest, Michigan to the north, Ohio to the east, the Ohio River and Kentucky to the south and southeast, and the Wabash River and Illinois to the west. Various indigenous peoples inhabited what would become Indiana for thousands of years, some of whom the U.S. government expelled between 1800 and 1836. Indiana received its name because the state was largely possessed by native tribes even after it was granted statehood. Since then, settlement patterns in Indiana have reflected regional cultural segmentation present in the Eastern United States; the state's northernmost tier was settled primarily by people from New England and New York, Central Indiana by migrant ...

Big Spring, Texas
Big Spring is a city in and the county seat of Howard County, Texas, United States, at the crossroads of U.S. Highway 87 and Interstate 20. With a population of 27,282 as of the 2010 census, it is the largest city between Midland to the west, Abilene to the east, Lubbock to the north, and San Angelo to the south. Big Spring was established as the county seat of Howard County in 1882; it is the largest community in the county. The city took its name from the single, large spring that issued into a small gorge between the base of Scenic Mountain and a neighboring hill in the southwestern part of the city limits. Although the name is sometimes still mistakenly pluralized, it is officially singular. "To the native or established residents who may wince at the plural in Big Spring, it should be explained that until about 1916, when for some unexplained reason the name dropped the final 's', the official name of the town was indeed Big Springs."

Edwards Plateau
The Edwards Plateau is a geographic region at the crossroads of Central, South, and West Texas. It is bounded by the Balcones Fault to the south and east, the Llano Uplift and the Llano Estacado to the north, and the Pecos River and Chihuahuan Desert to the west. San Angelo, Austin, San Antonio, and Del Rio roughly outline the area. The southeast portion of the plateau is known as the Texas Hill Country. Natural history The bedrock consists primarily of limestone, with elevations ranging between 100 and 3000 ft. Caves are numerous. The landscape of the plateau is mostly savanna scattered with trees. It mostly lacks deep soil suitable for farming, though the soil type is fertile mollisol, so some cotton, grain sorghum, and oats are grown. For the most part, though, the thin soil and rough terrain areas are primarily grazing regions, with cattle, sheep, and goats ( Angora and meat types) predominant. Several rivers cross the region, which generally flow to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mescalero Escarpment
The Mescalero Ridge forms the western edge of the great Llano Estacado, a vast plateau or tableland in the southwestern United States in New Mexico and Texas. It is the western equivalent of the Caprock Escarpment, which defines the eastern edge of the Llano Estacado. Mescalero Sands Extending north-south along the western edge of the Mescalero Ridge lies a vast sand sheet called the Mescalero Sands, named after the Mescalero Apaches who once hunted in these sandhills. In 1928, Nelson Horatio Darton of the United States Geological Survey observed: “On the east side of the Pecos Valley in southern New Mexico there are very extensive sand hills formed of deposits known as the ‘Mescalero Sands,’ which are doubtless of Quaternary age ...” In places, these sands climb up and over the Mescalero Ridge and spread out over portions of the Llano Estacado.

Permian
The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids ( reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
