Sierra Diablo
The Sierra Diablo is a small mountain range in the US state of Texas, extending north and south along the border between Hudspeth and Culberson counties. It is in the Chihuahuan Desert, and is near Van Horn, Texas. Geography The Sierra Diablo are a high mountainous plateau in West Texas. The highest peak in the range is 6,610 feet in elevation. The surface of the range slopes gently westward from its crest, but to the east, north, and south there are abrupt escarpments as high as 2,000 feet. The range contains the Sierra Diablo Wildlife Management Area, designated in 1945 to conserve the last remaining desert bighorn sheep in Texas. The highest peak in the range is known as Diablo Rim. Geology The oldest rocks of the region, exposed in the southern foothills, date from the Precambrian. The most extensively exposed rocks in the Sierra Diablo date from the Permian era, and are about 3,000 feet thick. They consist mostly of Hueco, Bone Spring and Victorio Peak limestones. Th ...

Texas Ranger Division
The Texas Ranger Division, commonly called the Texas Rangers and also known as ''Los Diablos Tejanos'' (), is an State bureau of investigation, investigative law enforcement agency with statewide jurisdiction in the US state of Texas. It is based in the capital city of Austin, Texas, Austin. In the time since its creation, the Texas Rangers have investigated crimes ranging from murder to political corruption, acted in riot control and as detectives, protected the List of governors of Texas, governor of Texas, tracked down fugitives, served as a security force at important state locations, including Alamo Mission, the Alamo, and functioned as a paramilitary force at the service of both the Republic of Texas, Republic (1836–1845) and the State of Texas. The Texas Rangers were unofficially created by Stephen F. Austin in a call-to-arms written in 1823 and were first headed by Captain Morris. After a decade, on August 10, 1835, Daniel Parker introduced a resolution to the Consult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victorio
Victorio (Bidu-ya, Beduiat; ca. 1825–October 14, 1880) was a warrior and chief of the Warm Springs band of the Tchihendeh (or Chihenne, often called Mimbreño) division of the central Apaches in what is now the American states of Texas, New Mexico, Arizona, and the Mexican states of Sonora and Chihuahua. In Victorio's War from September 1879 to October 1880, Victorio led a band of Apaches, never numbering more than 200 men, in a running battle with the U.S. and Mexican armies and the civilian population of New Mexico, Texas, and northern Mexico, fighting two dozen skirmishes and battles. He and most of his followers were killed or captured by the Mexican army in the Battle of Tres Castillos in October 1880. War leader and chief Victorio grew up in the Chihenne band. There is speculation that he or his band had Navajo kinship ties and was known among the Navajo as "he who checks his horse". Victorio's sister was the famous woman warrior Lozen, or the "Dextrous Horse Thief" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Texas–Indian Wars
The Texas–Indian wars were a series of conflicts between settlers in Texas and the Southern Plains Indians during the 19th-century. Conflict between the Plains Indians and the Spanish began before other European and Anglo-American settlers were encouraged—first by Spain and then by the newly Independent Mexican government—to colonize Texas in order to provide a protective-settlement buffer in Texas between the Plains Indians and the rest of Mexico. As a consequence, conflict between Anglo-American settlers and Plains Indians occurred during the Texas colonial period as part of Mexico. The conflicts continued after Texas secured its independence from Mexico in 1836 and did not end until 30 years after Texas became a state of the United States, when in 1875 the last free band of Plains Indians, the Comanches led by Quahadi warrior Quanah Parker, surrendered and moved to the Fort Sill reservation in Oklahoma.Frontier Forts > Texas and the Western Frontier/ref> The more than h ...

John George Walker
Major-General John George Walker (July 22, 1821 – July 20, 1893) was a Confederate general in the American Civil War. He served as a brigadier general under Stonewall Jackson and James Longstreet, before commanding the Texas Division unit in the Trans-Mississippi Department, known as Walker's Greyhounds for their speed and agility. He was ordered to disrupt U.S. Grant's supply-line opposite Vicksburg, Mississippi, but Grant had managed to cross to the East Bank, and Walker was reduced to minor operations, one of them against some of the first African-American troops to serve in battle. He was able to make a bigger contribution to the Red River Campaign in support of General Richard Taylor. Early life and career John George Walker was born in Jefferson City, Missouri.Eicher, p. 549. His mother Sarah Caffery Walker, was a niece of Rachel Jackson, the wife of Andrew Jackson. His father John Walker came from a distinguished political family from Kentucky and Missouri, with two ...

Battle Of The Diablo Mountains
The Battle of the Diablo Mountains was an October 1854 engagement between the U.S. Army and the Lipan Apache. A small force of Mounted Rifles attacked a much larger force of Lipan Apaches at the base of the Diablo Mountains in Texas. Battle Setting out from Fort Inge in South Texas on October 1, 1854, Captain John G. Walker, in command of around 40 men of the Mounted Rifles, headed for the Diablo Mountains region along the Rio Grande border with Mexico. Their mission was to investigate the reports from local settlers of stolen livestock, taken by Apache warriors. On the third day out, in the morning of October 3, 1854, Captain Walker and his men encountered well over 200 Lipan warriors near a herd of captured farm animals. Immediately Walker ordered an attack which surprised the Apaches significantly. A brief skirmish ensued and the Apaches quickly fled, leaving most of the stolen livestock. Casualties are unknown, except for Second Lieutenant Eugene Asa Carr who was wounded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lipan Apache
Lipan Apache are a band of Apache, a Southern Athabaskan Indigenous people, who have lived in the Southwest and Southern Plains for centuries. At the time of European and African contact, they lived in New Mexico, Colorado, Oklahoma, Texas, and northern Mexico. Historically, they were the easternmost band of Apache.Swanton, ''The Indian Tribes of North America'', p. 301 Early adopters of horse culture and peyotism, the Lipan Apache hunted bison and farmed. Many Lipan Apache descendants today are enrolled members of the Mescalero Apache Tribe in New Mexico.Mescalero Apache Research Report (2020), p. 3. Other Lipan descendants are enrolled with the Tonkawa Tribe of Indians ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beryllium
Beryllium is a chemical element with the symbol Be and atomic number 4. It is a steel-gray, strong, lightweight and brittle alkaline earth metal. It is a divalent element that occurs naturally only in combination with other elements to form minerals. Notable gemstones high in beryllium include beryl ( aquamarine, emerald) and chrysoberyl. It is a relatively rare element in the universe, usually occurring as a product of the spallation of larger atomic nuclei that have collided with cosmic rays. Within the cores of stars, beryllium is depleted as it is fused into heavier elements. Beryllium constitutes about 0.0004 percent by mass of Earth's crust. The world's annual beryllium production of 220 tons is usually manufactured by extraction from the mineral beryl, a difficult process because beryllium bonds strongly to oxygen. In structural applications, the combination of high flexural rigidity, thermal stability, thermal conductivity and low density (1.85 times that of water) ma ...

Tungsten
Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements barring carbon (which sublimes at normal pressure), melting at . It also has the highest boiling point, at . Its density is , comparable with that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten occurs in many ...

Silver
Silver is a chemical element with the Symbol (chemistry), symbol Ag (from the Latin ', derived from the Proto-Indo-European wikt:Reconstruction:Proto-Indo-European/h₂erǵ-, ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...
