Some rolls and slips were present, but the coal was never completely cut out by the rolls. The immediate roof above the coal varied. The cap rock was limestone up to 5 feet thick. Sometimes shale was present below the limestone. The shale ranged up to 15 feet thick. Draw slate was also present in some areas, and was generally less than 14 inches thick. The coal seam contained several layers with streaks of pyrite and bone coal less than 1 inch thick with thicker layers of dirty coal up to 1.5 feet thick. Bone coal and pyrite were not loaded with the coal mined. The floor was fire clay that ranged from 4 to over 6 feet thick.
