We know that the crew commonly shot Nimoy's footage in Los Angeles, and also in San Francisco. Occasionally they shot in New York.
I've asked my Los Angeles friends to have a look and they generally all agree that this cemetery is far too lush and green to be in the L. A. area.
Do you live in the bay area? Does this cemetery look familiar? Here are some things I've noticed:
1. It's got a hill in it. So if the cemetery is flat - that rules it out.
2. It's got what appear to be "into the hill" burial vaults, and some of the plots are set off with a metal bar in stone or concrete pillars. In the background on this shot you can see the vaults, one has red stone, another has what may be a rock and mortar edifice. Some celtic cross burial stones and an obelisk are in the background. None of this stuff is unique - but together might be good clues for verification.
I think this entrance gate is going to be a key identifier. I've seen a few gates like this but in my effort to drive around cemeteries in the bay area on Google Street View I've had no luck. Some of the cemeteries don't have a street view available.
So - does this gate or any of these shots look familiar? Can you provide any confirmation that you've found our mysterious graveyard shooting location? Let us know!
