Description

Rolley's (1951) map of the Herrin Coal Member (Pennsylvanian) shows a roughly equidimensional enclosed area covering about 1 square mile (2.5 km²). The current structure map of the Beech Creek ("Barlow") Limestone (ISGS open files) for the area indicates a dome having an area of closure somewhat larger than that mapped on the Herrin Coal. On the Beech Creek, the Blairsville Dome is nearly merged with the Bungay Dome. Oil fields have been developed on both structures.
