Mining in the London Mills Quadrangle
Most of the mining in the London Mills Quadrangle took place along the bluffs on the eastern side of the Spoon River, near Ellisville, in the Rock Island Coal. The coal had some concretions and pyrite was a noted problem in some areas, but the most prevalent difficulty was with thinning coal. The thin coal generally prevented expansion in some direction (often near topographic slopes), while small unmined areas within mine outlines were generally noted on the source maps as having poor roof condtions.
