This is the succession of strata on the spur south of Tannaki. 

 Along the crest of this spur runs a fault, which brings the dull red 

 sandstone of the infra-triassic series into contact with the cretaceous 

 formation. The sandstones dip down the north-western hill slope 

 covered by cherty dolomites, and come out again a little above Tannaki, 

 resting upon slates. 



The next ascent shows the same succession, but the slates reach 

 here far up the hill side. The different divisions of the infra-triassic
