What coal seams do I see exposed in the roadcuts along Interstate 79?
I-79 generally follows the outcrop of the Conemaugh Group. Although this formation does contain some locally minable coals, none are minable along the route of this interstate highway. The thick coals exposed near the Clarksburg/Bridgeport interchange at US Route 50 (exit 119) are the Pittsburgh and Redstone beds of the overlying Monongahela Group. The thick coal exposed between the Star City/Morgantown exit (exit 155) and the Pennsylvania state line is the Waynesburg bed at the top of the Monongahela Group.
