upward movement occurred and the area under discussion rose above the surface of the ocean where it remained during the enormous lapse of time that intervened between the closing centuries of the lower carboniferous and well along towards the close of the age when an almost worldwide world wide alde change of level occurred along the e east ast side of and parallel with what Is now known as the mt baldy tange range and its northern prolongation the range the earths crust was fissured from the surface down to the region deflon of molten rock the fissuring was succeeded by faulting and an idea of the tremendous displacement may be formed from the statement that deer trail peak the highest hig fiest elevation of quartzite is fully feet fee t higher than the valley while the eastern section of the quartzite zite is buried beneath hundreds of feet of basalt and other eruptive material the displacement extended northerly a distance of nearly miles in sevier valley the sandstone so
