Sutter's Mill was a water-powered sawmill on the bank of the South Fork American River in the foothills of the Sierra Nevada in California.

The mill was later reconstructed in the original design and today forms part of Marshall Gold Discovery State Historic Park in Coloma, California.

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 northeast of his existing colony.

[2] On January 24, 1848, while working on construction of the mill, Marshall found flakes of gold in the South Fork American River.

[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.

[10] 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.

The mill is referenced heavily in an episode of the television series Little House on the Prairie titled "At the End of the Rainbow," in which Laura Ingalls Wilder and a friend believe they have found gold in a stream near Walnut Grove.
