The Pope Mega Group is a geologic unit found in the Illinois Basin of southern Illinois, southwestern Indiana, and western Kentucky. In Indiana and Kentucky its equitant is the Buffalo Wallow Group. This unit grades from sandstones at its base into mix of limestones and sandstone and then a shale at its top. In Southern Illinois oil wells are drilled into the Tar Springs formation.
