Quadrangle: Granville.

Reason for Designation: Contains abundant & well-preserved deformed graptolites.
Graptolites are considered to be one of the best markers for the measurement of finite strain.
The site given is on accessible public property; this feature is located in other places in this area
but those are on private property. Exposures of deformed graptolites are rare in NYS and these
sites are especially unusual because they contain deformed graptolites in all structural positions in a fold.
