Geological Problems Reported

The roof consisted of 2 inches of draw slate with 2 to 12 inches of dark shale above. Sometimes a thin limestone band was found in the shale, but the cap rock was generally 18 inches of sandstone. The shale always came down where it was thin, and frequent concretions were noted in the shale. The roof was considered poor. Clay slips were sometimes encountered. The seam was uniform with no persistent bands of impurities. Pyrite nodules were occasionally encountered, and pyrite was also seen in vertical streaks.
