FLAXMAN ISLAND, A GLACIAL REMNANT 



6l 



Rivers, Schrader^ deals at some length with the glaciation of the 

 region. 



The glacial phenomena that have been described tend to show that, although 

 the Endicotte Mountains do not on the whole seem to have been overridden by a 

 moving ice cap, they were doubtless, especially in the northern part, largely occu- 

 pied by an ice cap or perennial neve constituting a breeding-ground for glaciers. 



The mountains he traversed reached an elevation of between five and 

 six thousand feet and he found no hving glaciers, yet a hesivy body 

 of ice pushed northward along the valley of the Coville. Around the

headwaters of the Kugura elevations of over seven thousand occur, 

 and valley glaciers^ of considerable size are reported to exist. Taking 

 these things into consideration, it is to be expected that the basin of 

 the Kugura would be occupied by a glacier of sufficient magnitude 

 to push thirty miles beyond the mountains and reach the sea. 



The presence of ground ice a few feet below the surface of the 

 tundra is a characteristic feature of the Arctic coastal plain. Dall^ 

 is of the opinion that it is a widespread phenomenon, but Schrader'^
