valley itself and the glacial river pouring southward in it, were grad- 

 ually extended from south to north as the ice front with its deep indenta- 

 tion receded. 



The most southeastern of these belts consists of somewhat rolling till 

 west of Golden Lake, in township 147, range 55, and includes the area of 

 very abundant bowlders which strew the bluffs of Fingals Creek or "Rocky 

 Run," in township 148, range 56. Thence a belt of morainic knolls and 

 hillocks, 10 to 40 feet high and occupying a width of half a mile, extends 

 northwestward tlu'ough sections 34 and 27, township 149, range 5.7, and 

 rises in hills 50 to 75 feet above the general level in the soutliwest part of 

 township 150, range 57, with numerous lakelets in the adjoining depres- 

 sions. This moraine continues westward in knolls and hills 25 to 50 feet 

 high to its junction with the Fergus Falls moraine, in the southern part of 

 towTiship 150, range 58, beyond which these two moraines seem to form a 

 compound series, in many places very conspicuously developed, to the west 

 part of the Turtle Mountain. 



Other morainic tracts, probably all extending soutliAvard to join the 

 preceding east of its union with the Fergus Falls moraine, were observed 

 on the western shore of Lake Agassiz, as follows: First, somewhat rolling 

 and hilly till 8 to 10 miles south of Larimore; second, knolls and swells of 

 till, sprmkled with abundant bowlders, in the southwest part of Elm Grove 

 township, crossed by the Great Northern Railway between the Herman 

 beach and Shawnee station ; and, third, moderately rolling and occasionally 

 hilly till, with many bowlders, in the east part of Oakwood, forming a belt 

 2 to 3 miles wide, which lies about 3 miles west of the last and is crossed 

 by the railway at and east of Niagara. 



Similar recessional morainic accumulations of till and bowlders were 

 also dropped on the western side of the Minnesota ice-lobe during its 

 retreat across the Red River Valley, Avliere it was rapidly melted back by 

 the la^^ng action of Lake Agassiz, between the chief stages of fonnation 

 of tlie ninth and tenth or Leaf Hills and Itasca moraines. In this class 

 may belong the remarkable profusion of bowlders found at a few points in 

 Gilby (township 153, range 53), one of which is commonly called "The 

 Island." Among other noteworthy localities of plentiful bowlders, the
