The Whitewater Formation is a geologic formation in Ohio and Indiana. It preserves fossils dating back to the Ordovician period.[1]
The Whitewater was first named by J. M. Nickles in 1903.[2] He described exposures of limestone and interbedded calcareous shale along the Whitewater River at Richmond, Wayne County, Indiana.
An excellent exposure of the Whitewater Formation is a roadcut located on Route 27 south of Richmond, Indiana, at 39.7877 N, -84.9014 W.
