On January 27, 1891, an explosion in the nearby Mammoth No. 1 Mine of the H.C. Frick Coke Company killed 109 coal miners. Seventy - nine of the dead were buried in a mass grave here in St. John's Cemetery. This disaster was the worst one known to that time in a bituminous coal mine in Pennsylvania. It led to state legislation strengthening the program of mine safety inspections in the bituminous fields.
