The Black Diamond Mines Regional Preserve is a 6,000-acre park located north of Mount Diablo in Contra Costa County, California. The East Bay Regional Park District acquired the property in 1973. The preserve contains relics of 3 mining towns, and former coal and sand mines. The district offers guided tours of a former sand mine. From 1850 to 1906, the area was known as the Mount Diablo Coalfield, the largest in California, producing more than 400×106 short tons of coal during this time. Rose Hill Cemetery, the final resting place for over 200 residents of the coalfield, is located on a hillside between the Somersville and Nortonville townsites. The cemetery is reputed to be haunted by the ghost of Sarah Norton, a locally famous midwife who met a violent death in October, 1879, by a run-away horse pulling her carriage.
