of Charlson in a southwesterly direction to the valley of Timber 

 Prong Creek in Sees. 14 and 15, T. 151 X., R. 07 W. It has a 



length of 10 miles, an average width of 2 miles, and its area is about 

 30 square miles. This moraine shows well from Charlson. where 

 its ridges and hills are seen rising from 100 to 150 feet above the 

 tlat plain in the foreground (Fig. 7 V Within the morainie area 

 the surface is rough ami hilly and the ground is thickly strewn with 

 bowlders. The topography is typically morainie. with numerous 

 irregular hills and ridges, while scattered among the hills are great 

 numbers of hollows or kettle-holes, some containing water and 



others dry. "Many of 

 the hills rise 50-125 feet 

 above the bottom of 

 the kettle-holes. 



Where this moraine 

 crosses the valley of 

 Timber Prong Creek it 

 forms a dam. which 

 holds back the waters 

 of the upper valley and 

 forms a lake known 

 locally as Dimick Lake. 

 This moraine lake is 

 very irregular in shape and has an area of between two and three 

 square miles. 



North of the Missouri River another morainie belt occurs 

 which may be part of the pre-Wisconsin moraine just described 

 as extending southwest from the vicinity of Charlson, though it 

 is perhaps more likely to have been formed by the Earlier Wiscon- 

 sin ice sheet referred to on another page. It lies from 2-3 miles 

 west of White Earth Creek and with a width oi 1-2 miles extends 

 north and south a distance of at least or S miles between the 

 Missouri River and the Great Northern Railroad. Fifteen or 20 

 miles or more west of the Altamont Moraine the railroad crosses 

 a well-developed moraine extending 4 or 5 miles and perhaps more 

 north and south of Temple, and has a width of several miles. This 

 hilly belt lies about miles west of the above-mentioned moraine 

 near White Earth Creek.
