The site of the mill is located on the South Fork American River. Marshall Gold Discovery State Historic Park is registered as California Historical Landmark number 530. The current Sutter's Mill is a replica of the original building. It was built based on Marshall's own drawings and an early day photo of the mill.
On January 24, 1848, James Wilson Marshall, a carpenter originally from New Jersey, found flakes of gold in the American River at the base of the Sierra Nevada Mountains near Coloma, California. At the time, Marshall was working to build a water-powered sawmill owned by John Sutter, a German-born Swiss citizen and founder of a colony of Nueva Helvetia (New Switzerland, which would later become the city of Sacramento.
“It made my heart thump, for I was certain it was gold."
Days after Marshall’s discovery at Sutter’s Mill, the Treaty of Guadalupe Hidalgo was signed, ending the Mexican-American War and leaving California in the hands of the United States. At the time, the population of the territory consisted of 6,500 Californios (people of Spanish or Mexican decent); 700 foreigners (primarily Americans); and 150,000 Native Americans (barely half the number that had been there when Spanish settlers arrived in 1769). In fact, Sutter had enslaved hundreds of Native Americans and used them as a free source of labor and makeshift militia to defend his territory and expand his empire.
