Summary

The key locality at NT 5016 8595, viewed towards the south-west. Well-bedded Marine Villa Tuffs in the low cliff on the left dip to the right (north-west} at c. 30 degrees. The fallen blocks lie along the axis of an open syncline. To the right (north-west) of the blocks, a thin ‘skin’ of Marine Villa Tuffs can be seen draping over a very shallow domed surface (with rucksack) of paler, coarse, massive Weaklaw Tuffs, that is elongated away from the camera. A dark recess in the cliff in the distance marks the overhang where near-horizontal, well-bedded Marine Villa Tuffs overlie Weaklaw Tuffs. Compare with Day (1923, plate XXIII) where, on both photos, the recessed overhang is marked 'x'.
