Summary:

To avoid confusion with the Genesee, the variant Geneseo is used for the 84 feet thick unit in the fall on Fall Brook, Geneseo, NY. The name Genesee is in duplicate use for the group (including the West River) and for the part beneath the Genundewa limestone, which is under water at Hall's type locality.
