    Perhaps another Leda clay landslip? I don’t know if there’s any up that way, but there are deposits of the stuff all over the Ottawa Valley, and down in the Southern Townships, and every so often several acres of land slump into the nearest ravine. There was a whole family killed near Drummondville quite recently by one of these events.
