Portions of the black shale roof (a minimum of 2 to 4 inches) were rotten, and were overlain by 2 inches of clod. The clod was dark gray and hard when fresh, but after exposure and oxidation, it became lighter and crumbled in the hand. The roof conditions in the northern part of the mine were very good; in the southern part, there was some soapstone. Limestone protrusions into the seam caused some difficulty with mining. Some slips were present in the black shale, especially around the protrusions. The shale was very hard to keep up and sooner or later was taken down up to the limestone cap rock. Concretions were present, but few in number. Squeezes were noted in the NE 1/4 of section 9 (1911 and 1924), and NW 1/4 of section 4 (1938).
