History
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.

Media
Sierra County is served by two long-running local newspapers. The Sierra Valley region, which is partially within Sierra County, is served by the Sierra Booster, based in Loyalton. This paper has been published bi-weekly since 1949 when it was established by reporter, miner, and airman Hal Wright and his wife Allene. It is today run by their daughter Janice Wright Buck.
The other paper serving the county is The Mountain Messenger which is based in Downieville. The Messenger has been in constant publication since 1853 and is currently the longest-running weekly newspaper in the state of California. Its more notable former contributor was Mark Twain, at the time in hiding from Nevadan authorities and writing under his birth name of Samuel Clemens.
This paper was the center of considerable media attention in early 2020 when its future was uncertain with the retirement of Don Russell, who had owned and operated it for 30 years; it was saved by local retiree Carl Butz, who purchased the paper and runs it today. The Mountain Messenger is printed every Thursday by Feather Publishing Co., based in Quincy; it is distributed across Sierra, eastern Plumas and western Nevada counties.
