SCENERY AND TOPOGRAPHY 



The writer only examined three small beaches in all 

 this stretch of coast. At Botany Bay, in Granite Har- 

 bor, a beach occurred about half a mile long composed 

 of granite bowlders. These were undoubtedly water- 

 w^orn, and nearby such bowlders extended fifty feet 

 above sea level. Perhaps here we have evidence of 

 uplift. David and Priestley describe raised marine de- 

 posits near Mount Larsen which may have been thrust 

 up by movement of large glacial masses. On the whole, 

 however, the shore lines seem to indicate subsidence, 

 as witness the drowned cirque at the head of Granite 

 Harbor, (See Figure 24.) 



Capes. — The importance of lists of capes as given 

 in the old-style geography is to be discounted, but it is 

 apparent that the capes in Antarctica are perhaps the 

 most important portions of the continent. Some are 

 historic, such as Cape Adare, Cape Armitage, Cape 

 Royds and Cape Evans. The occurrence of capes is 

 due, of course, to the presence of more resistant mate- 

 rial, while the less resistant has been hollowed out and 

 in general is still overwhelmed by the covering of ice. 

 Yet there has been ver^^ little marine erosion, so that 

 the coasts of Antarctica are characteristically linear or
