Two faults were shown on the company map, as was an area with sandstone roof. The sandstone roof was designated where mining did not occur, which indicates that the problems associated with this feature prevented economic mining. The roof material was generally 30 feet of massive gray shale, with 2 feet of sandstone below it noted at one location. This necessitated leaving 0.5 to 2 feet of top coal to support the roof, so that commonly only 7.5 feet of coal was mined. Pyrite bands of 0.5 to 0.75 inch thickness were noted in the samples taken.
