The slope of the above-water lip from original ground level down to,igea level varies over a wide range. To the south it ig-quite steep and the radius in that direction ranges from 360 to 410 ft. To the east and west, however, the slope is extremely gentle and the radius figure is consequently uncertain and of little significance. The maximm nepius appears to be (2) (3) (4) greater than 600 ft. From original ground level. eo Pf Since there was no lip the radius is not well defined.
