The fourth and largest outlier, immediatel}' behind the camera in plate 16, shows on the south side, from east to west, first a reversed fault, with a flexing of the sandstone and contact contrary to the apparent movement (figure 14). The sandstone is slickensided along the fault. Fifty feet west of this are two compensating slickensided faults of the.
