Wintu People
The Wintu (also Northern Wintun) are Native Americans who live in what is now Northern California. They are part of a loose association of peoples known collectively as the Wintun (or Wintuan). Others are the Nomlaki and the Patwin. The Wintu language is part of the Penutian language family. Historically, the Wintu lived primarily on the western side of the northern part of the Sacramento Valley, from the Sacramento River to the Coast Range. The range of the Wintu also included the southern portions of the Upper Sacramento River (south of the Salt Creek drainage), the southern portion of the McCloud River, and the upper Trinity River. They also lived in the vicinity of present-day Chico, on the west side of the river extending to the Coast Ranges. Today most Wintus live on reservations and rancherias in Colusa, Glenn, Yolo, Mendocino, and Shasta counties. History The first recorded encounter between Wintu and Euro-Americans dates from the 1826 expedition of J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trinity River (California)
The Trinity River (originally called the Hoopa or Hupa by the Yurok, and hun' by the Natinixwe/Hupa people) is a major river in northwestern California in the United States, and is the principal tributary of the Klamath River. The Trinity flows for through the Klamath Mountains and Coast Ranges, with a watershed area of nearly in Trinity and Humboldt Counties. Designated a National Wild and Scenic River, along most of its course the Trinity flows swiftly through tight canyons and mountain meadows. The river is known for its once prolific runs of anadromous fish, notably Chinook salmon and steelhead, which sustained Native American tribes for thousands of years. Due to its remoteness, the Trinity did not feature prominently in the early European colonization of California, but the gold rush in the mid-1800s brought thousands of gold seekers to the area. The river was named by Major Pierson B. Reading who, upon reaching the river in 1848, mistakenly believed it to flow into the ...

Pollution
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants have an anthropogenic source – that is, a source created by human activities. Pollution is often classed as point source or nonpoint source pollution. In 2015, pollution killed nine million people worldwide (one in six deaths). This remained unchanged in 2019, with little real progress against pollution being identifiable. Air pollution accounted for of these earlier deaths. Major forms of pollution include air pollution, light pollution, litter, noise pollution, plastic pollution, soil contamination, radioactiv ...

Gold Mining
Gold mining is the extraction of gold resources by mining. Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning. However, with the expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation. In the 20th and 21st centuries, most volume of mining was done by large corporations, however the value of gold has led to millions of small, artisanal miners in many parts of the Global South. Like all mining, human rights and environmental issues are common issues in the gold mining industry. In smaller mines with less regulation, health and safety risks are much higher. History The exact date that humans first began to mine gold is unknown, but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria. The graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least 700 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epidemic
An epidemic (from Ancient Greek, Greek ἐπί ''epi'' "upon or above" and δῆμος ''demos'' "people") is the rapid spread of disease to a large number of patients among a given population within an area in a short period of time. Epidemics of infectious diseases are generally caused by several factors including a significant change in the ecology of the areal population (e.g., increased stress maybe additional reason or increase in the density of a vector species), the introduction of an emerging pathogen to an areal population (by movement of pathogen or host) or an unexpected genetic change that is in the pathogen reservoir. Generally, epidemics concerns with the patterns of infectious disease spread. An epidemic may occur when host immunity to either an established pathogen or newly emerging novel pathogen is suddenly reduced below that found in the endemic equilibrium and the transmission threshold is exceeded. For example, in meningococcal infections, an attack rate in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malaria
Malaria is a mosquito-borne infectious disease that affects humans and other animals. Malaria causes symptoms that typically include fever, tiredness, vomiting, and headaches. In severe cases, it can cause jaundice, seizures, coma, or death. Symptoms usually begin ten to fifteen days after being bitten by an infected mosquito. If not properly treated, people may have recurrences of the disease months later. In those who have recently survived an infection, reinfection usually causes milder symptoms. This partial resistance disappears over months to years if the person has no continuing exposure to malaria. Malaria is caused by single-celled microorganisms of the ''Plasmodium'' group. It is spread exclusively through bites of infected ''Anopheles'' mosquitoes. The mosquito bite introduces the parasites from the mosquito's saliva into a person's blood. The parasites travel to the liver where they mature and reproduce. Five species of ''Plasmodium'' can infect and be spread by h ...

Peter Skene Ogden
Peter Skene Ogden (alternately Skeene, Skein, or Skeen; baptised 12 February 1790 – 27 September 1854) was a British-Canadian fur trader and an early explorer of what is now British Columbia and the Western United States. During his many expeditions, he explored parts of Oregon, Washington, Nevada, California, Utah, Idaho, and Wyoming. Despite early confrontations with the Hudson's Bay Company (HBC) while working for the North West Company, he later became a senior official in the operations of the HBC's Columbia Department, serving as manager of Fort Simpson and similar posts. Family Ogden was a son of Chief Justice Isaac Ogden of Quebec and his wife Sarah Hanson. The family was descended from a 17th-century British emigrant to the American colonies (Long Island and New Jersey). Both Isaac and his father David were Loyalists during the American Revolution; Isaac relocated to England at this time, then later returned to British-run Quebec. One of Peter's brothers, Charles Rich ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jedediah Smith
Jedediah Strong Smith (January 6, 1799 – May 27, 1831) was an American clerk, transcontinental pioneer, frontiersman, hunter, trapper, author, cartographer, mountain man and explorer of the Rocky Mountains, the Western United States, and the Southwest during the early 19th century. After 75 years of obscurity following his death, Smith was rediscovered as the American whose explorations led to the use of the -wide South Pass as the dominant point of crossing the Continental Divide for pioneers on the Oregon Trail. Coming from modest family background, Smith traveled to St. Louis and joined William H. Ashley and Andrew Henry's fur trading company in 1822. Smith led the first documented exploration from the Salt Lake frontier to the Colorado River. From there, Smith's party became the first United States citizens to cross the Mojave Desert into what is now the state of California but which at that time was part of Mexico. On the return journey, Smith and his compa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euro-American
European Americans (also referred to as Euro-Americans) are Americans of European ancestry. This term includes people who are descended from the first European settlers in the United States as well as people who are descended from more recent European arrivals. European Americans have been the largest panethnic group in the United States since about the 17th century. The Spaniards are thought to be the first Europeans to establish a continuous presence in what is now the contiguous United States, with Martín de Argüelles ( 1566) in St. Augustine, then a part of Spanish Florida, and the Russians were the first Europeans to settle in Alaska, establishing Russian America. The first English child born in the Americas was Virginia Dare, born August 18, 1587. She was born in Roanoke Colony, located in present-day North Carolina, which was the first attempt, made by Queen Elizabeth I, to establish a permanent English settlement in North America. In the 2016 American Community ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
