THE DRIFT.

tlie moraine westward we find, 

 however, that it gradually ap- 

 proaches the Giants range, 

 which has a trend to the south 

 of west, and crosses it in T. 63 

 N., R 9 W. West of this point 

 the ice tongue reached a point 

 considerably farther south, and 

 it had sufficient strength to ad- 

 vance well up the slopes of the 

 range, but was never able to 

 surmount it. From here on 

 the moraine is found l}ang fii'st 

 high up upon the northern 

 slope of the range, with the 

 distance increasing between it 

 and the range as we go farther 

 west. In the western portion 

 of the district it is nearly 15 

 miles north of the range. , 



Exceptionally heavy deposits 

 of drift are known to occm- 

 in the following areas: Sees. 

 21-28, T. 61 N., R. 15 W., and 

 extendmg from there on up to 

 the northeast in a belt approx- 

 imately 2 miles wide through
