The sketch is a stylised view based upon a photograph of the western face of the western Hanging Rock (Figure 6). Most of the face above the base of the Marine Villa Tuffs is crumbly and inaccessible and hence parts of the interpretation might be inaccurate. Figure 2 fro...

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.
