The Big Hill mine in Lucas worked a coal seam below the surface using room and pillar methods, with a shaft not far from the Burlington station. This mine was closed in April 1904 and stripped of equipment, but by mid-1905, plans were in place to reopen it. The reopening lasted until 1907, when the mine was again closed, as the rock directly above the coal was sandstone and it was saturated with water. This mine is noteworthy because John L Lewis got his first coal mining job here, before going on to head the United Mine Workers of America.
