Sierra County (Sierra County)
Sierra County is a county located in the U.S. state of California. As of the 2020 census, the population was 3,236, making it California's second-least populous county. The county seat is Downieville; the sole incorporated city is Loyalton. The county is in the Sierra Nevada, northeast of Sacramento on the border with Nevada.

Sierra County was formed from parts of Yuba County in 1852. The county derives its name from the Sierra Nevada.

Prior to the California Gold Rush, the area was home to both the Maidu and the Washoe peoples. They generally summered in the higher elevations to hunt and fish, and returned to lower elevations for the winter months. After the discovery of gold in the Sierra foothills sparked the California Gold Rush, more than 16,000 miners settled in Sierra County between 1848 and 1860. Most mining settlements in the county sprung up along the North and Middle Forks of the Yuba River, both of which had rich deposits of gold. While some of the mining boom towns faded away once gold fever died down, other settlements such as Downieville and Sierra City have remained.

Notable gold nuggets found in the county include a 26.5 pound specimen, avoirdupois, found by a group of sailors at Sailor Ravine, two miles above Downieville. A 51-pound specimen was found in 1853 by a group of Frenchmen in French Ravine. The 106 pound Monumental Nugget was found in Sept. 1869 at Sierra City.

The Bald Mountain drift mine in Forest City was founded in Aug. 1864, and was the largest of its kind in the state at the time. The Bald Mountain Extension was located in 1874 east of Forest. The Monte Cristo Mine was located in 1854. The largest quartz-mine is the Sierra Buttes Gold Mine was located in 1850 near Sierra City. The Gold Bluff Mine was located near Downieville in 1854. By 1880 the county was "crushing" 70,000 tons of quartz and had 266 miles of mining ditches.

The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C., and its most populous city and principal financial center is New York City.

Indigenous peoples have inhabited the Americas for thousands of years. Beginning in 1607, British colonization led to the establishment of the Thirteen Colonies in what is now the Eastern United States. They quarreled with the British Crown over taxation and political representation, leading to the American Revolution and proceeding Revolutionary War. The United States declared independence on July 4, 1776, becoming the first nation-state founded on Enlightenment principles of unalienable natural rights, consent of the governed, and liberal democracy. The country began expanding across North America, spanning the continent by 1848. Sectional division surrounding slavery in the Southern United States led to the secession of the Confederate States of America, which fought the remaining states of the Union during the American Civil War (1861–1865). With the Union's victory and preservation, slavery was abolished nationally by the Thirteenth Amendment.
