Summary:

Forge Hollow dolomite of Bertie group. Rank raised to formation in Bertie group. Overlies Fiddlers Green dolomite; underlies Oxbow dolomite (new). Fieldwork has not demonstrated lateral continuity of Forge Hollow and Scajaquada as indicated on present chart. Thick glacial deposits conceal these units in area where they may merge. Possibility of facies changes -- for example, Falkirk to Forge Hollow -- should not be overlooked. For the present, the distinct names are retained for western and central New York.
