The entire eastern base is composed of the acid series just described, most characteristic being the red coarse granite with large quartz grains and sparsely and crudely mingled horn blende. Even at a great distance from the south one can de teet the broad light stripe of obliquely tilted limestone where it is exposed by some vast eruptive outburst which not only tore open the very vitals of the mountain but plowed an enormous furrow across the lime and thus made good its escape to the south and east.
