Mining in the Ewing Quadrangle
The oldest mining known to have taken place in the Ewing Quadrangle is a small area in the southwestern corner, extending from a large mine on the West Frankfort Quadrangle. The Middle Fork Mine ([[0139|mine index 139}}) worked in the Herrin Coal, which was over 6 feet thick. Thick Herrin Coal extends over the remainder of the quadrangle, at a depth of 700 to 800 feet. The M-Class No. 1 Mine (mine index 1047) began operation as a longwall mine in 2010.
