I know this is bad, I'm going to put flowers on my close friend grave. But I haven't go to visit contained by a long time. (almost a year of his death)

This graveyard doesn't have Tombstones. It have Flowers. - and a a plate or something in the ground. - But whats bleak is. I don't know where he is? (I know its bad) But I haven't see him since he had to be put within the ground.

Is there some means of access you can look up where they are located at?
Because this gray patio is big! Help please.
Answers:    Most graveyard have a keep guy. There is probably a master sheet telling where on earth everyone is. Call the cemetery and ask.
Call the churchyard
