154 THE GLACIAL LAKE AGASSIZ. 



with bowlders than its sides, is about 125 feet above the general level, 

 or 300 feet above the Sheyenne. In tlie view from this hill I traced 

 faint indications of the course of the Dovre moraine in a curve passing- 

 northwest, north, and northeast to the similarly prominent hill 2 miles 

 west-northwest of Valley City. The highest hills of the moraine in this 

 distance of 7 miles rise about 60 feet above the general level in sections 11 

 and 2, township 139, range 59. All the surface from this loop eastward 3 

 or 4 miles to the Sheyenne Valley is a very smooth, fertile tract, apparently 

 the flood-plain of the river when it flowed about 175 feet above its present 

 level, at the time of the retreat of the ice-sheet from this moraine. 



In section 18, township 140, range 58, 1^ miles north of the Northern 

 Pacific Railroad and slightly tarther northwest of Valley City, a prominent 

 tract of morainic drift, probably owing part of its height to an underlying 

 hummock of the Cretaceous shale, rises 100 feet above the old gravel and 

 sand flood-plain of the Sheyenne on the east or about 300 feet above the 

 river. The surface of this elevation is abundantly strewn with bowlders 

 and is very irregularly broken by ravines, hillocks, and small ridges, trend- 

 ing from south to north to its highest point and thence trending toward the 

 west-northwest, indicating that there was here another reentrant angle 

 of the ice margin. Looking across the country west-northwestward, I ob- 

 served low knolls and ridges of this moraine, scarcely above the general 

 level, extending at least 2 or 3 miles; but no prominent hills are visible in 

 this direction. Two to 3 miles north of Hobart this moraine curves north- 

 ward, and passes as a narrow belt of knolly drift north and northeast through 

 the east half of township 141, range 59, and across the Sheyenne to the 

 northeast part of township 142, range 58, where it becomes partially merged 

 with the Fergus Falls moraine. Thence turning back by a right angle, it 

 recrosses the Sheyenne about a mile above the mouth of Bald Hill Creek 

 and extends northwestward along the east side of this creek. Its most 

 prominent portion, called Bald Hill, lies 5 miles east of Dazey and extends 

 along a distance of 2 miles or more from southeast to northwest, rising some 

 300 feet above the Sheyenne or fully 100 feet above the general level. 



Tlu'ough Griggs County the Dovre moraine is very well developed 

 and forms especially conspicuous hills west and north of Cooperstown,
