248 THE ANTIQUITY OF MAN IX TASMANIA. 



Tasmania refer to this area, very little is still known 

 about it; we even do not know its exact limits. It ap- 

 pears that in the west and north the terminal moraines 

 reached down to a much lower level than in the west 

 Montgomery stated that on the Upper Pieman the); 

 descended to a level of 500 to 600 feet. On the Uppef 

 Forth I nowhere observed them to descend lower than 

 1,500 feet. 



(b) THE BEN LOMOND CENTRE OF 

 GLACIATION. 



The extended plateau of Ben Lomond towers in the 

 north-east corner of Tasmania up to a height of 5,000 

 feet. So far I have not visited it, but photographs ex- 

 hibited by Colonel Legge show plainly moraines, roches, 

 moutonnees — in fact all the characteristic features of a 

 surface formerly covered by ice. Mount Cameron, 

 which I visited, shows the dome-like, roundish features 

 which have been recognised as signs of a former glacia- 

 tion. 



(c) THE MOUNT WELLINGTON CENTRE OF 

 GLACIATION. 



Though almost at the gates of Hobart very little is 

 known about this area. It extended probably towards 

 west as far as Port Davey, where the dome-like figure 

 of Mount Misery indicates glaciation. 



Now, whichever view we take, it seems pretty certain 

 that all that portion which is at pre&ent 2,000 feet and 

 more above sea level was once glaciated, forming a 

 nevee. This probably sent out large glaciers, which de- 

 scended if not into the sea probably close to the sea 

 level. I estimate the area under glaciation at roughly 

 6,000 square miles — that is to say, one-quarter of the 

 present Tasmania. This proves that the climatic condi- 

 tions of Tasmania during the glacial period must have 

 been considerably different from those of Tasmania of 

 the present day. It is pretty certain to assume that the 

 same conditions that produced the glaciation of the high- 

 lands of Tasmania prevailed also on the Antarctic con- 

 tinent ; in other words, that the ice reached much further
