Mining in the Tower Hill Quadrangle
Mining began in the northeastern quarter of the Tower Hill Quadrangle sometime before1870 near the town of Robinson Creek (mine index 7451 and mine index 7452) and before 1875 near Henton (mine index 7445 and mine index 7446). Most of the mining took place in the bluffs along Mud Creek and Robinson Creek, generally drift mines into the Shelbyville Coal.
The largest mine in the area is the Tower Hill Mine (mine index 0318), which undermined much of the town of Tower Hill from 1903 to 1912. The Herrin Coal was mined at a depth of about 800 feet.
