Quadrangle: Portageville.

Reason for Designation: The Wiscoy Formation marks the top of the West Falls Group & this locality
contains the contact between the Wiscoy/Dunkirk formations West Falls/Canadaway groups that coincides
with the Frasnian/Famennian boundary & the mass extinction event that occurs at that boundary. The large,
well exposed surfaces are excellent for studying many different aspects of the depositional environment of the
Late Devonian up to the 5th largest mass-extinction in Earth's history.
