The Pennsylvania Bureau of Topographic and Geologic Survey 's " Distribution of Pennsylvania Coals " map show 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 ) refer 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 seem a small coal mine operated there in the past .
