The Pioneer Cemetery, as it is now known, is located on Cold Springs Road across from the Vineyard House in Coloma. In the past, the cemetery has been called various names: Sutter Mill, Coloma Protestant and Vineyard. Although the Coloma Protestant Church was organized April 22, 1850, the exact date that the cemetery was founded is unknown. The earliest known graves date from 1849. Robert Chalmers, who built the Vineyard House, and his family are buried in the cemetery. Chalmers was the earliest recorded owner of the land where the cemetery is located. Over the years, the land passed through the hands of the Mary Kane family to the County of El Dorado who deeded the cemetery property to the California Department of Parks and Recreation on August 3, 1981. Since that time, the cemetery has been a part of the Marshall Gold Discovery State Historic Park.
