In August 2015, while digging on Route 61 in Schuykill County, construction crews discovered a decade-old mass human burial site believed to have belonged to victims of the Spanish Influenza. Approximately 1,600 locals died in one month from the virus, and it was not uncommon for people to be buried in large unmarked graves like this one, as grave diggers could not keep up with the demand for individual graves.
They conducted DNA tests on the remains and gave proper burials to the individuals in the graves.
