scenery in the Rocky Mountains. It has been 

 mapped and studied, and its rate of movement 

 and many other things concerning it are accu- 

 rately known. It is the abstract and brief chron- 

 icle of the Ice Age, a key to all the glacier ways 

 and secrets. 



In the Arapahoe Glacier one may see the 

 cirque in which the snow is deposited or drifted 

 by the wind; and the bergschlund-yawn 

 crack of separation made by glacier ice where 

 it moves away from the neve or snowy ice above. 

 In walking over the ice in summer one may see 

 or descend into the crevasses. These deep, wide 

 cracks, miniature canons, are caused by the ice 

 flowing over inequalities in the surface. At the 

 end of this glacier one may see the terminal 

 moraine, a raw, muddy pile of powdered, 

 crushed, and rounded rocks. Farther along 

 down the slope one may see the lakes that were 

 made, the rocks that were polished, and the 

 lateral moraine deposited by the glacier in its 

 bigger days, times when the Ice King almost 

 conquered the earth.
