| Stratigraphy comments: "Trenton limestone" (Flower, 1952 p. 50). Nothing more is said on the stratigraphy. In the section at West Canada Creek as much as 5 formations are exposed (Rathbun Mbr. of Sugar River Fm. - Upper Mbr. of Steuben Fm.). Brett & Baird (2002, Phys. Chem. Earth 27(1-3)) give the time interval that is spanned by these rocks as Shermanian. | |||||
