I have been told that they took all the rock from Whiterock during WW2. >From what is in this article there started many years before the war started. Le Grand Advocate, Friday, April 13, 1928 Shipment of Whiterock to Los Angeles continues at the rate of about two carloads a week, about 43 tons to the load. There is an unlimited number of things that can be made from this whiterock and there is an unlimited amount of whiterock up around Whiterock, so these shipments will probably continue for an unlimited time. -- Thomas and Paulette Hilk 1725 Wildwood Ct.
