The California Gold Rush

The first printed notice of the discovery was in the March 15 issue of "The Californian" in San Francisco. Shortly after Marshall's discovery, General John Bidwell discovered gold in the Feather River and Major Pearson B. Reading found gold in the Trinity River. The Gold Rush was soon in full sway.

In 1849, quartz mining began at the Mariposa mine in Mariposa County. Gold deposits were often found inside quartz veins. In 1850, California became a state. Also that year, gold-bearing quartz was found at Gold Hill in Grass Valley. This led to the development of the great underground mines in that district and a major industry the continued for more than 100 years.

In 1851, Gold was discovered in Greenhorn Creek, Kern County. This discovery led to the rush to the upper Kern River region. By 1852, California's annual gold production reach a then all-time high of $81 million.

Other important dates and discoveries:

In 1853, the first extensive underground mining of buried river channels commenced in the Forest Hill District, Placer County.

Also in 1853, the placers at Columbia, Tuolomne County, began to yield vast amounts of gold. This continued until the early 1860s. At that time, Columbia was one of the largest cities in the state.

A partial exodus of miners took place in 1853 when gold was discovered on the Fraser River in British Columbia.

In 1854, a 195-pound mass of gold, the largest known to have been discovered in California, was found at Carson Hill in Calaveras County.

By 1855, the rich surface placers were largely exhausted, and river mining accounted for much of the state's output until the early 1860s.

In 1859, the famous 54-pound Willard nugget was found at Magalia in Butte County.

By 1864, California's gold rush had ended. The rich surface and river placers were largely exhausted; hydraulic mines were the chief sources of gold for the next 20 years.
