THE SEVENTH OR DOVRE MORAINE. 155 



rising 75 to 150 feet above the adjoining country. From Bald Hill it 

 takes a very straight course a little west of notith for 15 miles to the center 

 of township 146, range 59, 2 to 3 miles west of Coopei'stown, having 

 through this distance an average width of a mile and consisting of many 

 knolls and small hills of till, with abundant bowlders, rising 25 to 50 feet 

 above the nearly level surface on each side. Toward the west this belt is 

 bordered along much of its extent by an overwashed plain of gravel and 

 sand, about a mile wide, descending by a very gentle slope away from 

 the moraine, which thus has a very definite boundary; but on the east 

 there is a gradual change through a decreasingly knolly and rolling con- 

 tour to the slightly uiadulating expanse of intermorainic till, with only few 

 bowlders, which stretches 4 to 6 miles east to the Sheyenne Valley and 20 

 miles north between the moraine and the Sheyenne, from Bald Hill to the 

 scattered hills of a reentrant angle of this Dovre moraine 4 to 6 miles north 

 of Cooperstown. 



About 5 miles farther north another angle of the moraine is marked 

 by the conspicuous hill called Butte Mashue, from the name of an Indian 

 who was buried in a mound on its summit. This hill, situated in the east 

 half of section 35, township 148, range 59, rises 150 or 175 feet above the 

 general level east and north, or nearly 350 feet above the Sheyenne River, 

 which is only 1 mile distant at the northeast. It is a typical morainic drift 

 hill of small area, irregularly knolly contour, and very abundant bowlders. 

 Its diameter of base is only a third to a half of a mile. On the township 

 line south of this section 35 there is a hollow a quarter of a mile wide, 

 through which a road runs from east to west, nearly 150 feet below the top 

 of the Butte Mashue. Immediately to the south, in the north edge of sec- 

 tion 2, a very rocky and typically morainic north-to-south ridge rises about 

 125 feet; and thense a series of hills and short morainic ridges, 75 to 125 

 feet high, extends south to the irregularly scattered hills of similar heights 

 which occupy most of the area between Cooperstown and Clear Lake. 



Unusual numbers of limestone bowlders were observed in this vicinity 

 on the morainic hills and adjacent to them, including many 6 to 8 feet in 

 diameter, one mass 10 by 15 feet in dimensions, and another, seen close 

 east of the south-to-north road about a mile south of the Butte Mashue,
