THE glaciers, which geologists tell us at one time cov- 

 ered this state, had a great deal to do with forming 

 that class of land which we term "forest land." In 

 places they left great heaps of sand, gravel and boulders; in 

 other places these deposits were strewn for a stretch of miles 

 in length and several miles in width. Today we can see 

 everywhere the results of the action of the ice in the hills, 

 valleys, lakes and streams. 



To read of these facts and to see the dull maps which illus- 

 trate them does not convey to one who is not an enthusiastic 

 geologist a very vivid picture, but if one has even a vague 

 idea as to the results of the glaciation he can thoroughly 

 enjoy a well-chosen course of overland travel (not by rail- 

 road). During the first part of August I had an opportunity 

 of taking such a trip, covering in all about three hundred 

 miles through the northern portion of Crow Wing county, 

 southern Cass, the southeastern part of Becker and the south- 

 ern portion of Hubbard counties. My object was to deter- 

 mine in the first place the character of the land and the for- 

 est conditions in the portions of the counties enumerated. 

 After visiting the hilly region in northeastern Crow Wing 

 county in the vicinity of Crooked Lake, I realized the neces- 

 sity of correlating the hilly regions which had elsewhere 

 Deen only vaguely brought to mind. 



Condition Most Favorable for Establishment of Growing 

 Forest. 



From Crooked Lake it was possible to make out a well- 

 defined range of hills bearing in a northwesterly and south- 

 easterly direction. These hills are for the most part terminal 

 moraines, with abrupt slopes and more or less rounded tops.
