Summary:

Kenwood Siltstone Member of Borden Formation is a wedge of sediment that thins from 110 ft to zero across a width of 10 mi and that extends for 50 mi along depositional strike from southern Indiana southeastward into north-central Kentucky. Composed of siltstone and interbedded shale. Siltstone was deposited by turbidity currents that flowed towards the southwest down the front of the Borden delta to where it was deposited with the shaly bottomset beds. Kenwood overlies and is intertongued with New Providence Shale Member. Overlain by Nancy Member where not overlain by tongue of New Providence. Age is Mississippian (Osage Series).
