The stratigraphy is complex, and unfortunately, some of it is permanently gone. Most of the vertebrate material seems to lie in the dark layered clay, and dark clay with sand and gravel. These clays contain lenses and layers of angular chert gravel, with clasts of local dolomite. They had gravel beneath them along Route 75, and probably graded laterally into the gravels. Within the lower part of the dark clays are a number of large dolomite blocks. The dark clay and gravels overlie a thick horizon of gray layered clay. Layers above the dark clays are now missing.
The Tennessee Department of Transportation drilled seventeen holes along the two planned rights of way, and twelve additional on the Barry Property, the remaining part of the hill south of the excavation. They indicated an area perhaps 700 feet long underlain by layered clays. One drill hole indicated the presence of additional dark carbonaceous clay at depth, beneath the thick gray layered horizon.
