Fayette stade follows New Paris interstade (new) and is followed by Connersville interstade (new). Fayette drift (new name) seems to be bracketed by radiocarbon dates of >40,000 and 20,000+/-500.

Ice that deposited the Fayette Till invaded southwestern OH approximately 21,000 years ago. Sand lenses, stringers, and layers are very common suggesting repeated retreat and readvance of the ice. Near Oxford, there are two units composing the Fayette that have different colors, compositions, and fabrics. The subsurface Fayette extends southward in this region to the Butler-Hamilton County boundary. Characteristically the Fayette contains much wood and macerated organic material. Till is usually gray and has a northeast fabric orientation. Overlies Fairhaven Till and underlies Shelbyville Till.

Based on new amino-acid data, the Fairhaven Till is now believed to be Illinoian and the Whitewater Till pre-Illinoian, rather than early and middle Wisconsinan as previously thought. Therefore, the late Wisconsinan Fayette Till is the basal Wisconsinan till in the area.
