Created in 1851, from portions of Yuba County, Nevada County was named after the mining town of Nevada City, a name derived from the Sierra Nevada Mountains. The word nevada is Spanish for “snowy” or “snow-covered.” Charles Marsh was one of the first settlers in what became Nevada City, and ts perhaps the one who named the town. He went on to build extensive water flumes/ditches/canals in the area, and was influential in the building of the first transcontinental railroad and the Nevada County Narrow Gauge Railroad.

Nevada City was the first to use the word “Nevada” in its name. In 1851, the newly formed Nevada County used the same name as the county seat. The bordering state of Nevada used the same name in 1864. The region came to life in the Gold Rush of 1849. Many historical sites remain to mark the birth of this important region in California’s formative years. Among them are the Nevada Theatre in Nevada City, the oldest theater built in California in 1865. It operates to this day and once hosted Mark Twain, among other historical figures. The Old 5 Mile House stagecoach stop, built in 1890, also operates to this day as a provider of hospitality spanning three centuries. This historical site still features “The stagecoach safe” that is on display outside the present-day restaurant and is the source of many legends of stagecoach robbers and notorious highwaymen in the California gold rush era. The gold industry in Nevada County thrived into the post-WWII days.

The county had many firsts and historic technological moments. The first long-distance telephone in the world, built in 1877 by the Ridge Telephone Company, connected French Corral with French Lake, 58 miles (93 km) away. It was operated by the Milton Mining Company from a building on this site that had been erected about 1853. The Pelton wheel, designed to power gold mines, still drives hydroelectric generators today. Nevada City and Grass Valley were among the first California towns with electric lights. The Olympics, NASA, and virtually every television station around the country uses video/broadcasting equipment designed and manufactured by Grass Valley Group, founded in Grass Valley.

The Nevada County Narrow Gauge Railroad, built in 1876, was the only railroad in the West that was never robbed, though its primary freight was gold. (Builder-owner John Flint Kidder’s reputation made it clear that he would personally hunt down and kill anyone who tried.) The rail line closed in 1942 and was torn up for scrap.

In Grass Valley, the historic Holbrooke Hotel opened in 1851 and housed Mark Twain, Bret Harte, and four U.S. Presidents (Ulysses S. Grant, Grover Cleveland, Benjamin Harrison, and James A. Garfield).

The community of Rough and Ready seceded from the Union for a time and became the Great Republic of Rough and Ready.

Nevada County is home to the Empire Mine State Historic Park, which is the site of one of the oldest, deepest, and richest gold mines in California. The park is in Grass Valley at 10791 East Empire Street. In operation for more than 100 years, the mine extracted 5.8 million ounces of gold before it closed in 1956.

In 1988, the 49er Fire was accidentally started by a homeless and schizophrenic local man near Highway 49. The fire went on to burn well over 100 homes and more than 33,000 acres in Nevada County.

The 2001 Nevada County shootings occurred on January 10, 2001, in which Scott Harlan Thorpe murdered three people in a shooting spree. Two of the victims were murdered in Nevada City and a third victim was killed in Grass Valley. Thorpe was arrested and declared not guilty by reason of insanity. He currently resides in Napa State Hospital.

According to the U.S. Census Bureau, the county has a total area of 974 square miles (2,520 km), of 16 square miles (41 km) (1.6%) are covered by water. The county is drained by Middle and South Yuba Rivers.

The western part of the county is defined by the course of several rivers and the irregular boundaries of adjoining counties. When the county was created, the founders wanted to include access to the transcontinental railroad, so a rectangular section was added that includes the railroad town of Truckee.

Nevada County is one of four counties in the United States to border a state with which it shares the same name (the other three counties are Texas County, Oklahoma; Delaware County, Pennsylvania; and Ohio County, West Virginia).


The county has substantial areas of forest, grassland, savanna, riparian area, and other ecosystems. Forests include both coniferous- and oak-dominated woodland types. Also, numerous understory forbs and wildflowers occur, including the yellow mariposa lily (Calochortus luteus).
