F. E. WRIGHT — EFFECTS OF GLAOIAL ACTION IN ICELAND 



The net result of the ice-sheet action, if continued long enough, would 

 be, therefore, a truncation of the mountains at a common level, strongly 

 resembling in appearance an uplifted marked and dissected peneplain. 

 Ice-sheet beveling is suggested as a possible factor in the development of 

 the observed upland surfaces, both in north Iceland and in the Coast 

 Eange of southeastern Alaska.
