San Francisco’s Ocean Beach was the final resting place of two hundred-year-old tombstones that washed ashore in 2012. One was the tombstone of Delia Presby Oliver, who died at the age of 26 on April 9, 1890, and the other was of Emma Bosworth, who died in 1876. There is an explanation. For a time, the giant granite tombstones within the San Fran city limits were repurposed (after the bodies were moved) as construction material, including a sea wall at Ocean Beach in the 1940s to help with the erosion problem. Regardless. it’s still creepy.
