West of Prince William Sound we saw glaciers in

 Unimak and Unalaska islands but only one was visited 

 or approached so closely as to permit the making of ob- 

 servations worthy of record. 



The Grewingk Glacier is one of a series descending the 

 northwest slope of the mountainous Kenai Peninsula. It 

 was mapped by Dall in 1880, and revisited in 1895, when 

 he made accurate note of the position of the ice front with 

 reference to an object on the southern wall of the valley. 

 In 1899 he accompanied me to the edge of the glacier for 

 the purpose of pointing out this object, and I made a few 

 photographs and other observations to aid in the recog- 

 nition of future changes. 



The glacier descends with moderate grade from a high 

 neve, and maintains in its lower part a width of one and 

 one-third miles. Its front is three miles from the sea, the 

 interval being occupied by a gravel plain. For half the
