There are many graves in the cemetery. The graves weren't that old; the oldest grave I saw was from 1913.
There are 3000 Indians buried at the mission. Most of them don't have crosses on their graves.

The skull is a symbol of death. There were tiles like these on both sides of the gates. One was in English, and one in Spanish.
Cross
This is one of the graves. It looked old.
