Faults are shown where they intersect the Herrin or Springfield Coal and not where they intersect the bedrock surface. Although all faults are “concealed,” they are shown with solid lines where accurately located and with dashed lines where approximately located, inferred, or projected through unmined areas.hhcathhchchhatdatcmatatsathshatsdhcmcmcmhcmhchcmcmhhsssshatathdddcmhchchchphhchccmhccchhhpmmmmmcmJNJNJNJJNJNJNJNJNJNJNJNJNJNJNJJNJNJNJNJNJNJNJNJNJNJNJNJNJNJNJNJNJNJNJN+(((((((((((((JNJNJNJN+++((((+++(((++((++(((+(++(((áJNJNJNJNJNJNJNJNJNJNJNJN++(((++((+++((((+++(((JNJNJNJNJNJNJNJNJNJNJNJNJNJN555555555555JNJNJNJNJNJNJNJNááJN((((((((((((((((NCOTTAGE GROVE MASTER FAULT!!!!!Absher Dike250300150200400100150200450250100350300150250200350¾Á½½¾½¾¾Á½½½oo76"e"ekG"k"k"e"e"k"k"e"e"k"e"e"e"e"k"k"e"k"k"k"k*ÜG"e"k"e*ÜG*ÜG*ÜSG*ÜSG"k"kܪG"k"k"ekG"k"e*Ü"e"k"k"k"k"k"k"k"e"k"e"e"e"e"e"k"k"k"k"k"k"k"k"k"k"k"k"k"k"k"k"k"k"kGSܪG"k"e"e"e"ekGkGª"eܪG"k"kS*ÜSG"k"k"e"e"e"k"k"k"k"e"e"e"e*GCB"ekG"k"k"e"e"e"k"k"k"kkG"kS"k"k"k"k"e"e"k"k"e"e"e"e"kS"kªGªG"e"e"k"kS"kªG"eªG"e"e"e"kS"k"e"e"e"e"k"k"e"e"e"e"ekGS"k"kC"k4112786940701401956113306830053221100282269829447247346477131987737981316484458442821147493387012375536862184332005421968726229911001622152122222241882282462672932763319205762725284206257920914493028006519142279950276257249246946201237276257305192223217618013963691701652825226333CBCBCBCBCB6019664243148706245375548527681604548595147265702746190251654926228472771513518711560189740151162605015251552760616463621857039328502794159197102027944022823995809569221202207Qe&cQe&csmsmsm&csm&tsm&m&tsmsm&tsm&tsm&tsm&c&msmsmsmsm&t&c&c&msm&m&c&msm&c&t&cQe&m&msmsm&m&m&cQesmsmsmsm&tQesm&csmsmQesm&csmsmQeQeQeQeQesm&tQeQeQeQeQeQeQeQe
