CACHE IS NOT AT THE POSTED COORDINATES! But it is nearby. You will need to complete the CSQ: Sylvan Cemetery Adventure Lab.
CSQ = California Spirit Quest
I've seen spirit quest series in other states, and wanted to try and start a trend here in California. This is to bring attention to some interesting graves that might not have gotten attention otherwise. Please, as always, be respectful of the area.
While the cache is NOT located within the cemetery, you will need to complete the Adventure Lab that is within the cemetery.
Operating hours are:
