NORTH MOWICH GLACIER.'' 



The North Mowich Glacier is the 

 northernmost of the series of ice bodies 

 on the west flank of Mount Rainier. 

 Like the Carbon Glacier, it heads in a 

 cirque at the base of the Liberty Cap 

 massif, fed by direct snow precipitation, 

 by wind drifting, and by avalanches. 

 The cirque is small and shallow, not as 

 capacious even as either of the twin 

 recesses in the Carbon Glacier's amphi- 

 theater. As a consequence the ice 

 stream issuing from it is of only moderate 

 volume; nevertheless it attains a length 

 of 3% miles. This is due in part to the 

 heavy snows that reenforcc it through- 

 out its middle course and in part to over- 

 flows from the ice fields bordering it on 

 the south. These ice fields, almost 

 extensive enough to be considered a 

 distinct glacier, are separated from the 



North Mowich Glacier only by a row 

 of pinnacles, the remnants evidently of 

 a narrow rock partition of "cleaver," 

 now demolished by the ice. The lowest 

 and most prominent of the rock spires 

 bears the appropriate name of "The 

 Needle" (7,587 feet). 



The debris-covered lower end of the 

 glacier splits into two short lobes on a 

 rounded boss in the middle of the 

 channel. This boss, but a short time 

 ago, was overridden by the glacier and 

 then undoubtedly gave rise to an ice 

 dome of the kind so numerous farther up 

 on the North Mowich Glacier and also 

 characteristic of the Winthrop Glacier.
