From Kakanui Quarry the outcrop of the Kakanui limestone and underlying tuffsruns north to Trig. L, a distance of three-quarters of a mile. The dip of the limestoneis east—that is, towards the sea. From the quarry northward half a mile the limestoneforms the sea-cliffs, the trend of the coast in this stretch running parallel with the strike. Rocbdj Oldj Qu,ajrry.
