of 



rainal debris were transported only a few miles, 

 while the Wisconsin and Iowa glaciers brought 

 thousands of acres of rich surfacing, now on the 

 productive farms of Ohio, Illinois, and Iowa, 

 from places hundreds of miles to the north in 

 Canada. In the Rocky Mountains most of the 

 forests are growing in soil or moraines that were 

 ground and distributed by glaciers. Thus the 

 work of the glaciers has made the earth and the 

 mountains far more useful in addition to giving 

 them gentler influences, charming lakes and 

 flowing landscape lines. It is wonderful that 

 the mighty worker and earth-shaper, the Ice 

 King, should have used snowflakes for edge- 

 tools, millstones, and crushing stamps! 



To know the story of the Ice King to be 

 able to understand and restore the conditions 

 that made lakes and headlands, moraines and 

 fertile fields will add mightily to the enjoy- 

 ment of a visit to the Rocky Mountains, the 

 Alps, the coasts and mountains of Norway and 

 New England, Alaska's unrivaled glacier realm, 

 or the extraordinary ice sculpturing in the Yo- 

 semite National Park.
