Exposures
The Sharon conglomerate has no formal type section,[2] although it is named after the town of Sharon, Pennsylvania.
One excellent exposure is located in Cuyahoga Valley National Park at "the Ledges," located southeast of the town of Peninsula, Ohio. Another exposure is at Mary Campbell Cave near Cuyahoga Falls.
