 The Pennsylvania Bureau of <unk> and <unk> Survey 's " Distribution of Pennsylvania <unk> " map shows no major deposits of coal in the Plunketts Creek watershed , and only one deposit nearby in the Loyalsock Creek watershed ( in southern Plunketts Creek Township ) . However , Meginness ( 1892 ) refers to coal mines in Plunketts Creek Township , and there is an unnamed tributary of Plunketts Creek in " Coal Mine Hollow " on the right bank between Dry Run and King Run , so it seems a small coal mine operated there in the past .
