Charles Fenner : 



The low country, with gentler slopes east of Fault B, is of tertiary 

 and terrace material, with a little low-level glacial in the northern 

 part. The southern and lower part of Bald Hill, enclosed b;^ 

 faults D, C, and part of B, is a block of permo-carboniferous 

 glacial sandstones, with a distinct easterly dip. The remaining 

 area in the plan, the western portion, consists of high steep hills 

 of older basalts, dipping down under tertiary leaf beds to the 

 south. Not only have we this distinct geological evidence, but three 

 of the four faults in this small area have been selected as stream 

 valleys. The field evidence for fault C is good ; although no section 

 is to be seen, the junction between the glacial sandstones and the 

 older basalt is a straight line that msfj be traced over the hill, for 

 about a mile in length and at least 300 feet in vertical height. Just 

 before reaching the bed of the Korkuperriniul, it is intersected by 

 another fault, D, running south-easterly.

 rimul Creek, near the letter D. Fig. 10. The older basalts are 

 let down against Permo-carboniferous glacial rocks. 



The fault marked C probably continues westward, but since it 

 there cuts through older basalt alone, it is not easy to follow. 

 Where it would cross the Korkuperriniul creek, there is some evi- 

 dence of its continuation tlirough the older basalts on the right 

 bank. The Korkuperriniul does not quite follow the fault line, D, 

 but lies more in the older basalts of the western side, and in its 

 bends provides conclusive sections of this fault. Going down the 

 creek, we find a steep cliff of glacial on the left bank where the 

 Korkuperriniul has taken a sweep in that direction; at both ends
