This is a typical miniature example of glaciers like the Rhone 

 glacier, Switzerland, and the Davidson glacier, Alaska. 



Most of the glaciers on the Cascades have a lower limit of 

 about six thousand feet ; the majority of them are west of the 

 Cascade divide, and are either in immediate proximity to or on 

 Glacier Peak and the sides of lateral ridges branching from it ; 

 or else on somewhat detached peaks, some of them ten to twenty 

 miles west of the Cascade divide. Of these outlying groups of 

 glaciers, the most numerous are at the heads of high grade val- 

 leys in the granitic peaks about Monte Cristo, as has been 

 observed by Bailey Willis, and on similar granitic peaks border- 

 ing the upper course of Skagit River. There is also an outlying 

 group of glaciers on Mt. Baker and neighboring mountains. 



The broadest neve fields and most numerous glaciers occur 

 on Glacier Peak and the rugged mountains surrounding it. The 

 snow fields in this region cover a rugged area some ten square 

 miles in extent, and are confluent ; from this gathering ground 

 there flow several short ice streams, or rather ice tongues, as 

 none of them have a characteristic stream-like form. The neve 

 extends up the sides of the culminating cone of Glacier Peak and 

 occupies the remnant of a crater still recognizable at its summit. 

 From the top of Glacier Peak fully fifty glaciers are in view 

 within a radius of about thirty miles. But little, if any, differ- 

 ence in the distribution of these glaciers can be recognized, on 

 looking northward or southward, thus indicating that their exist- 

 ence depends rather on general climatic conditions, than the occur- 

 rence of previously formed cirques, or the shelter afforded by 

 lofty peaks. 



Lituya Bay, Alaska. — This bay was visited and mapped by La 

 Perouse, in 1786. It has the shape of the letter T. The cross 

 arm of the bay was not surveyed but was drawn in from descrip- 

 tions of the officers who visited it. La Perouse speaks of five 

 large glaciers coming down to the water, two at each end and 

 one at the side of the cross arm. The maps of the Canadian 

 Boundary Commission, made about 1894, show that the side 

 glacier has diminished, but that the two glaciers at each end of
