July is the one month that the Mammoth Site in Hot Springs changes from an informational center for visitors to an archeological dig site, Rapid City Journal reports.
Earthwatch diggers are the volunteers that remove the many layers of dirt at the Mammoth Site in order to find something far more significant, pre-historic fossils.
From Texas to Belgium, the diggers are from all parts of the world. Their responsibility is to unearth the soil found at the Mammoth Site, put it in containers and then start the process over again.
The Earthwatch diggers are at the Mammoth Site through the month of July, and the Mammoth Site encourages visitors to come and watch the process.
