There are thousands of lost and stranded cemeteries in the world. Many are hidden in the woods, others are being slowly eaten by construction and particularly by shopping center parking lots.
When you see them, stop and take photos of all of the markers and of the site. Transcribe the inscriptions and put the photos and text on Find-a-grave so at least the images of the stones and cemeteries have a chance to survive modern man.
Old family cemeteries are particularly hard hit by developers in modern society, as witnessed in most of the satellite photos associated with the locations below.
If you know of other locations, add the map link to them in a comment to this post and they will be added to the list.
