Salado Springs
Salado Springs is the name of five groups of springs at the town of Salado in Bell County, Texas, in the United States. The springs are located 48 miles (77 km) north of Austin or 135 miles (217 km) south of Dallas. The springs, which are not saline (''salado'' is Spanish for "salty"), were likely named for Salado Creek. Geography and natural history The Salado Springs are located in the Balcones Fault zone, and they reach the surface through artesian pressure by way of faults in the Cretaceous Edwards limestone. The main recharge area for the springs is probably several miles to the southwest in Williamson County, where several faults intersect with Salado Creek. The larger of the springs include Robertson Springs, Big Boiling Spring, Elm, Benedict, and Anderson springs. The latter three are located downstream (east) of the others. During the 1980s, the combined flow from all of the springs averaged approximately 122 gallons (460 liters) per second. The ...

Salado, Texas
Salado ( ) is a town in Bell County, Texas, United States. Salado was first incorporated in 1867 for the sole purpose of building a bridge across Salado Creek. In 2000, the citizens of Salado voted in favor of reincorporation, before which it was a census-designated place. The population was 2,394 at the 2020 census. History Archaeological evidence of a paleolithic Native American settlement dating back about 15,500 years, the Buttermilk Creek Complex, has been unearthed in Salado. The first record of white settlers in the area occurred in 1834, but by 1836, the pioneer settlers abandoned the area due to frequent Indian attacks and the invasion by General Santa Anna and the Mexican Army. The first permanent Anglo-American settler at Salado was Archibald Willingham in 1850. In 1852, the Salado Post Office was established. In 1859, the Salado College Joint Stock Company was created by Col. Elijah Sterling Clack Robertson, who donated 320 acres north and south of the springs to ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', " chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Ear ...

Mill (grinding)
A mill is a device, often a structure, machine or home appliance, kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many process (engineering), processes. There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a crank (mechanism), hand crank), working animal (e.g., horse mill), wind (windmill) or water (watermill). In modern era, they are usually powered by electricity. The grinding of solid materials occurs through mechanical forces that break up the structure by overcoming the interior bonding forces. After the grinding the state of the solid is changed: the grain size, the grain size disposition and the grain shape. Milling also refers to the process of breaking down, separating, sizing, or classifying aggregate material (e.g. mining ore). For instance rock crushing or grinding to ...

Chisholm Trail
The Chisholm Trail was a trail used in the post- Civil War era to drive cattle overland from ranches in Texas to Kansas railheads. The trail was established by Black Beaver, a Lenape guide and rancher, and his friend Jesse Chisholm, a Cherokee merchant. They collected and drove numerous cattle along the trail to Kansas, where they could be shipped east to achieve higher prices. The southern terminus was Red River Station, a trading post near the Red River along the northern border of Texas. The northern terminus was a trading post near Kansas City, Kansas. Chisholm owned both of these posts. In the years of the cattle drives, cowboys would drive large herds from ranches across Texas to the Red River Station and then north to Kansas City. Overview Texas ranchers using the Chisholm Trail had their cowboys start cattle drives from either the Rio Grande area or San Antonio. They joined the Chisholm Trail at the Red River, at the border between Texas and Oklahoma Territory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juan Antonio Bustillo Y Ceballos
Juan Antonio Bustillo y Ceballos (Zevallos) was a soldier and politician who served as governor of Province of Texas (1730–1734) and Coahuila, New Spain (1754–1756). He also served as ''alcalde ordinario'' (ordinary mayor) in Mexico City. Early life Ceballos was born between the late seventeenth and early eighteenth centuries. He settled in Texas in 1723, living there for twelve years. Governor in Texas Between 1724 and 1731 he served as captain of the Presidio Nuestra Señora de Loreto de la Bahía. In 1730, he helped restore Querétaro missions in San Antonio (originally were in East Texas) and in the following year, the viceroy of New Spain, Juan de Acuña, appointed him governor of Texas. He arrived to Los Adaes, Texas' capital, on April 28, 1731, carrying ''several hundred of heads of livestock'' and many supplies. He promoted the settlement of Spanish settlers from the Canary Islands in Bexar (modern San Antonio) in 1731. In the following year, Bustillo led ...

Geologic Fault
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A '' fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can bl ...

Williamson County, Texas
Williamson County (sometimes abbreviated as "Wilco") is a county in the U.S. state of Texas. As of the 2020 census, its population was 609,017. Its county seat is Georgetown. The county is named for Robert McAlpin Williamson (1804?–1859), a community leader and a veteran of the Battle of San Jacinto. Williamson County is part of the Austin-Round Rock-Georgetown metropolitan statistical area. It was included with Austin in the Best Cities to Live in for 2009 by the Milken Institute. It is on both the Edwards Plateau to the west, rocky terrain and hills, and Texas Blackland Prairies in the east, rich, fertile farming land. The two areas are roughly bisected by Interstate 35. History Prehistoric Much of Williamson County has been the site of human habitation for at least 11,200 years. The earliest known inhabitants of the area lived during the late Pleistocene (Ice Age), and are linked to the Clovis culture around 9,200 BC based on evidence found at Bell County's m ...

Artesian Aquifer
An artesian aquifer is a confined aquifer containing groundwater under positive pressure. An artesian aquifer has trapped water, surrounded by layers of impermeable rock or clay, which apply positive pressure to the water contained within the aquifer. If a well were to be sunk into an artesian aquifer, water in the well-pipe would rise to a height corresponding to the point where hydrostatic equilibrium is reached. A well drilled into such an aquifer is called an ''artesian well''. If water reaches the ground surface under the natural pressure of the aquifer, the well is termed a ''flowing artesian well''. Fossil water aquifers can also be artesian if they are under sufficient pressure from the surrounding rocks, similar to how many newly tapped oil wells are pressurized. From the previous statement, it can be inferred that not all aquifers are artesian (i.e., water table aquifers occur where the groundwater level at the top of the aquifer is at equilibrium with atmospher ...
