Rose Hill Cemetery, officially designated as a Protestant cemetery, the final resting place for over 200 residents of the coalfield, is located on a hillside between the Somersville and Nortonville townsites. After the mines closed and the nearby towns were abandoned, the cemetery fell into disuse. Many of the gravestones were stolen or destroyed by vandals. In 1960, Ansel Adams photographed two Italian Cypress trees in the cemetery, and called the image,"Poplars, Cemetery near Mount Diablo". The photo was taken with a Polaroid camera, though it's possible that it was not a typical consumer camera model.
