Dutch Flat, CA
Dutch Flat (also, Dutchman's Flat, Dutch Charlie's Flat, and Charley's Flat) is a small unincorporated community and census-designated place (CDP) in Placer County, California, United States, about 30 miles (48 km) northeast of Auburn along Interstate 80. It was founded by German immigrants in 1851 and was once one of the richest gold mining locations of California. Its ZIP code is 95714 and its area code 530.
Dutch Flat was founded by two German brothers, Joseph and Charles Dornbach. To the south of their settlement was the busy mining camp of Green Valley, where 2,000 men were at work when the Dornbachs arrived. Across the Bear River in Nevada County was another camp, Little York, and just west, a trading post at Cold Springs (later known as Gold Run). All these camps were supplied by mule train from Illinoistown, near today's Colfax. The muleskinners referred to the Dornbach's camp as 'Dutch Charlie's Flat,' and thus the town was named.
