In this east belt the UpperStones River pure limestones are well exposed and largequarries opened. The Lower series is absent and the Middleis very thin, so that the cauliflower cherts of the Beekman-town are only a few feet distant from the Upper same is true on the east quarry belt at the Standardsouth quarries. The southern end of the outcrop of the west belt on theNational property is of exceptional purity, running 99 percent, carbonate of lime in car-load lots. At this pure outcropthe Chambersburg Limestone is faulted out and the UpperStones River is overlain by Martinsburg Shale. There is alsoan overturn of the strata at this place and this lime
