Upper half is a brownish-gray to blue-gray, fine- to medium-grained, siliceous dololutite that is markedly cherty with much interstitial silica; chert is mainly stringy or hackly. Thickness is 40 ft at type locality. Unconformably underlies Cranesville dolomite (new); unconformably overlies Fonda member (new) of Tribes Hill formation.
