At original ground level}‘yhich was approximately 15 ft
above sea level. 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
