Coal was mined on the eastern side of Mount Diablo as early as 1860. In time, five towns grew up around the mines. Nortonville, the largest, served as home to more than 1000. By the middle of the 20th century, the easy-to-reach coal had been exhausted and the area was abandoned, but for heaps of slag and a graveyard full of stories.
The Rose Hill Cemetery was almost completely obliterated by vandals and the well-meant preservation tactics of the early park rangers. In the 1990s, vandalism intensified after Antoinette May featured the cemetery in Haunted Houses of California. In the last couple of decades, the park staff has reassembled the headstones as if they were puzzles and brought the graveyard back to life.
Guiding us on our exploration will be a historian and naturalist from the Black Diamond Mines Regional Park.
