 The Money Bin also has a worry room in which Scrooge paces around in circles, which has caused a circular depression in the floor, to worry and ponder about hardships that has befallen him.The worry room was first mentioned in Carl Barks' story "The Secret of Atlantis" ("Uncle Scrooge" #5, 1954).The traditional location of the Money Bin is on top of Killmotor Hill which in turn lies atop a fault line which would prove catastrophic in the event of an earthquake, and this earthquake occurred in the story "Land Beneath the Ground!"
