A visit to your local graveyard can provide not only a history lesson, but a science lesson as well. Historians know that gravestones can reflect the lives of people whose memories are lost in time, and they have long scoured old burial sites to piece together the stories of those who rest there.
But today scientists are learning much more from those letters carved in stone. Gravestones are telling the story of changes in Earth’s atmospheric chemistry and rainfall. Moreover, scientists are asking for your help to read the stones.
