Plains appear to be faulted on' both the Monaro block and 

 the mountain masses to the south of Dalgety. The recency 

 of the faulting is shown by the canon growths. The head 

 Snowy has not receded in canon form to the Main Divide 

 through the Kosciusko block. Moreover the lower river 

 has not yet cut its canon to Dalgety ; neither has the stream 

 above Dalgety yet quite cut its way from the Dalgety block- 

 to the Jindabyne senkungsfeld, while the tiny streams 

 traversing the eastern wall of the senkungsfeld have only 

 succeeded in notching the edge of the escarpment. The 

 slowness of the warping movement is indicated by the 

 absence of traces of an important lake at Jindabyne, which 

 must have existed 1 if the river had not maintained itself 

 against the uplift from Dalgety to Jindabyne. 



In concluding this chapter it may be stated that the 

 Murrumbidgee, Shoalhaven, Macquarie, Clarence, Barron 



that Eastern Australia has a series of highlands arranged 

 along its periphery and " curving sympathetically " with 

 the coast line. The bulk of these mountain blocks are due to 

 to faulting and the blocks so raised are dissected by deep 

 gorges. The surface topography of the various blocks is 

 similar, although they are separated by immense scarps. 

 If the ravines [which cause the plateaus to be almost 

 inaccessible] could be filled again with rock material, and 

 if, moreover, the flexed and faulted blocks could be letdown 

 into the positions they occupied prior to the flexing and 

 faulting action, then we should have the appearance of 

 a peneplain mildly roughened with broad shallow valleys 

 and dotted over with isolated residuals of an older pene- 

 plain surface.
