Photograph of the original Sutter's Mill, taken circa 1850
The territory of Alta California, which includes modern-day California, was settled by the Viceroyalty of New Spain from 1683 onwards. It became part of an independent Mexico in 1821. John Sutter, a German-Swiss settler, arrived in the region in 1839. He established a colony at New Helvetia (now part of Sacramento), in the Central Valley. The United States conquered the region during the Mexican–American War (1846–1848): California was overrun by US forces in 1846 and a ceasefire in the region was agreed in January 1847. A peace treaty for the wider war had not yet been completed when Sutter decided to begin construction of a sawmill in the forest about 30 miles north-east of his existing colony. Sutter employed James Wilson Marshall, a carpenter originally from New Jersey, to supervise construction of the new building.[2]
On January 24, 1848, while working on construction of the mill, Marshall found flakes of gold in the South Fork American River.[2] On February 2, 1848, before news of the discovery had arrived, the Treaty of Guadalupe Hidalgo was signed in Mexico City. This peace treaty formally transferred sovereignty over the region to the United States. Two workers at the mill, Henry Bigler[3] and Azariah Smith,[4] were veterans of the Mormon Battalion and recorded their experience in journals.[5] Bigler recorded the date when gold was discovered, January 24, 1848, in his diary.[6] Sutter's claim to the US government for mineral rights was investigated by Joseph Libbey Folsom, who issued confirmation of the gold discovery in June. The first flake found by Marshall was shipped to President James K. Polk in Washington DC, arriving in August 1848.[2] It is now on display in the National Museum of American History, part of the Smithsonian Institution.[2][7]
As news of the gold spread, settlers flocked to the new US territory of California. The population expanded from 14,000 non-natives to an estimated 85,000 newcomers[contradictory] in just a year.[8] There were roughly 81,000 newcomers[contradictory] in 1849 and another 91,000 in 1850.[9] Many settled at the new town of Coloma, California, which sprung up close to Sutter's Mill. Numerous further discoveries of gold in California were made. During the next seven years, approximately 300,000 people came to California (half by land and half by sea) to seek their fortunes from either mining for gold or selling supplies to the prospectors. This California Gold Rush permanently changed the territory, both through mass immigration and the economic effects of the gold. California became a US State in 1850.
On September 8, 1965, a groundbreaking was held to begin the construction of a replica of the original structure, based on Marshall's own drawings and a photograph of the mill taken circa 1850.[11] The replica was nearly completed by the following year, and while not built at the exact spot as the original, it was designed to be moved there if the river returned to its 1848 stream bed.[12] The newly completed replica was officially dedicated on January 21, 1968.[13][14] In 2014, the 1960s structure was replaced with a new replica, built closer to the original site.[15][16]
On April 22, 2012 a meteor entered the Earth's atmosphere and exploded, showering meteorite fragments over parts of California and Nevada. The first samples of this meteorite fall were recovered close to Sutter's Mill, so it was named the Sutter's Mill meteorite. Several dozen fragments were eventually identified, with a total weight of about a kilogram. The meteorite is classified as a carbonaceous chondrite and contains some of the oldest known material in the Solar System.[17]

This small piece of yellow metal is believed to be the first piece of gold discovered in 1848 at Sutter's Mill in California, launching the gold rush. James Marshall was superintending the construction of a sawmill for Col. John Sutter on the morning of January 24, 1848, on the South Fork of the American River at Coloma, California, when he saw something glittering in the water of the mill's tailrace. According to Sutter's diary, Marshall stooped down to pick it up and "found that it was a thin scale of what appeared to be pure gold." Marshall bit the metal as a test for gold.

The Mormons did not like to leave my mill unfinished, but they got the gold fever like everybody else. After they had made their piles they left for the Great Salt Lake. So long as these people have been employed by me they hav [sic] behaved very well, and were industrious and faithful laborers, and when settling their accounts there was not one of them who was not contented and satisfied.
