Darien Center Submember of the lower part of the Wanakah Member of the Ludlowville Formation (of Brett and others, 1986, and Miller, 1991) is a well-defined 3- to 5-m interval bounded by the Mt. Vernon Bed at its base and the Bidwell Bed at its top. Included between these two bounding beds are the Stolle Road Bed, the Girdle Road Bed, the Lakeview Bed, the Darien Coral Bed, the Fargo Bed, and the Murder Creek Bed. Original descriptions of most beds are credited to Kloc (1983: unpublished MA thesis).

Excellent, closely spaced stream-bank exposures of the Darien Center Submember at the base of the Wanakah Member of the Ludlowville Formation occur throughout most of the study area from the Lake Erie shore to Hopewell Gully, east of Lake Canandaigua in Ontario Co, a distance of more than 100 km. Submember represents a regressive-transgressive cycle with a nearly symmetric pattern of storm bed types and faunal assemblages, including the Mt. Vernon Bed, which marks the base, and the ascending Lakeview, Darien Coral, Murder Creek, and Bidwell beds discussed in this report. Darien Center divided into Taphofacies I-VI.
