I lived in Medicine Park, Oklahoma while growing up. Loved Meers burgers. And Sqaw Tit mountain was nearby (very un-PC). There was a creek near Meers where we used to swim.
Didn't know there was a fault there.
I was stationed at Ft. Sill and spent a good deal of time reading about and wandering in the Wichita Mountains Wild Life refuge during my time off. You can get info about the fault and its activity from the Oklahoma Geological Survey site.
