|Geologic age||Upper Silurian|
|Original map label||Sab|
|Comments||part of Akron Dolostone and Salina group 400-700 ft. (120-210 m). Secondary unit descriptions from USGS Lexicon website (ref. NY046) and references NY029 and NY030: Akron Dolostone included in Bertie Group, but referred to as Akron-Cobleskill strata. Consists of very fine grained rocks in the Canadian sections and approaches a mottled waterlime in character. Included in Bertie because rocks are so similar to typical Bertie strata below, especially to the Victor Dolostone. Generally 3 to 5 m thick. Overlies Williamsville Formation. Age is Late Silurian (Ciurca and Hamell, 1994). Bertie Group redefined. Author includes the Akron-Cobleskill interval and the newly named Moran Corner Waterlime in his revised Bertie Group. Term Rondout Formation is restricted to its type area in southeastern NY. In this report, Bertie Group in western NY subdivided into (ascending) Fort Hill Waterlime, Oatka Formation, Fiddlers Green Formation, Scajaquada Formation, Williamsville Formation, Cobleskill Formation-Akron Dolostone, and Moran Corner Waterlime. Fort Hill and Moran Corner Waterlimes absent in Ontario, CAN (Ciurca, 1990).|
