The roof consisted of over 3 feet of black shale with large balls of iron pyrite. The top coal was dark, soft, and often broken. No faults were seen, but clay dikes were common, some displacing the coal up to 18 inches. Gypsum was common in the mine, generally seen as a 1/4 to Β½ inch lens that was 6 to 7 inches long. In the upper third of the coal seam, a 2 to 3 inch thick cannel coal was noted. The clay dikes were exceptionally large, quite frequent in occurrence, and often ran through the entire seam thickness. One was observed to be 12 feetlong and 4 feet wide.
