I've marked up aerial maps with the name and location of each visible and readable grave marker, using the Prospect Hill map. Prospect Hill has a lot of unknown graves because of vandalism, markers sinking into the ground, and the gravestones on the oldest plots being too weathered to read.
Click the links on the map below, to see the image with that sections marker names. I'll post them as I get them done. These will be a work in progress and may change often, since I'll need to verify some of the information by visiting the cemetery.
