The heights of these terraces in general cheek with those given by Tindale 
1933, save Cave Range, which is shown as 175 fect, as against the earlier estimate 
of 200 feet, Baker Range was regarded by Tindale as the earliest phase of his 
East Avenue Terrace, while Dairy Range is a portion of his Woakwine complex. 
Ward examined the possibility of these terraces being eustatie terraces, but 
following earlier expressed views reiterated that they weve the results of inter- 
mittent epeirogenie movements of uplift on a regional seale. One or more 
terraces were considered to be fault lines developed in Post-Tertiary times, and 
“due to the relief of the epeirogenie stresses developed in the general uplift of 
the region.’’ Diffieulty was seen in reconciling the apparently orderly sllecess1on. 
of terraces with the relative lengths of past interglacial periods. ‘' Should proof 
be forthcoming that the oldest ridge lies farthest inland, and that each StIeGessive 
ridge is younger than that more remote from the sea, it would appear that the 
hypothesis of purely eustatie control under glacial influence must be abandoned.’ 
Tu the light of other work these objections may be less valid, since they are 
common to other eustatic shorelines on stable foreshores. 
Edwards (1941) after studying the north-west coast of Tasmania came to 
the conclusion that its submergent and emergent features were die largely to 
successive custatie rises and falls of sea level during the Glacial and Post-Glacial 
periods. No one stage of either high or low sea level was maintamed sufficiently 
long to allow the coastline to mature so that it is made up of youthful features of 
submergence combined with youthful features of emergence, Kast of Devonport 
the shore features due to submergence tended to dominate, evidence that this part 
of Tasmania was well sheltered from marine erosion except during interglacial 
highs. West of Stanley the shore features, due to emergence, were the more 
prominent. 
Edwards gave records of high terraces at many places along the north coast
