Founders - Whittier

California law allows an inactive cemetery to be declared a public nuisance and closed. Go here - http://whittiermuseum.org/research/cemeteries/ - to read how this happened to Whittier's adjacent Mt. Olive and Broadway cemeteries in 1959. They were converted to, and remain, a public park. 1,291 were buried here. Some were moved to other cemeteries by their families, but most remain under the added layer of soil that now covers their graves.
The removed headstones were first stored at the Pio Pico Adobe, then at the Whittier Museum. With a few historically significant exceptions, they are now in Acton, CA. Dale Bybee agreed to remove the headstones at his own expense. http://www.avoidingregret.com/2016/04/photo-essay-fake-cemetery-with-real.html
