Description

Cady et al. (1939) and Rolley (1951) called this feature an anticline, but it is more accurately called a dome. Their mapping of the Herrin Coal Member (Pennsylvanian) and subsequent mapping of the Beech Creek ("Barlow") Limestone by Bristol (1968) and the Karnak Limestone Member of the Ste. Genevieve Limestone (Mississippian) by Bristol and Howard (1976) indicated a kidney-shaped structural high having irregular areas of closure. Walpole Oil Field, developed on the structure, has produced more than 10.6 million barrels from Chesterian, Valmeyeran, and Devonian reservoirs. The Walpole Dome is connected by saddles to the Hoodville and Dale Domes.
