highest points of the inoraiue and 200 feet above the Sheyenne, that on 

 the west being till and that on the east stratiiied gravel and sand 1 to 2 

 miles wide, dividing the moraine from the trough-like Sheyenne channel or 

 valley. From near the center of this township the morainic belt, contin- 

 uing with inconspicuous development, passes northeastward across the 

 Sheyenne, and at the northeast corner of this township and in section 6 of 

 that next east the drift, heaped in a reentrant angle of the ice border, forms 

 Standing Rock Hill, rising 100 feet above the general level and about 300 

 feet above the river. Thence this moraine turns back by a right angle to 

 the west and northwest, recrossing the Sheyenne and rising in hills 50 

 to 100 feet high, through sections 34, 27, 28, 21, 20, and 17, township 137, 

 range 58, approaching within a mile of the equally prominent hills of the 

 Waconia moraine at its reentrant angle in the next township on the west. 



Continuing thence to the north, the Dovre moraine is represented by a 

 naiTOW series of knolls, 20 to 30 or 40 feet above the general level, through 

 township 138, range 58, veering slightly to the east, and closely skirting 

 the west side of the Sheyenne Valley across the northern half of the town- 

 ship. Its drift covers the east slope and top, and its bowlders are sti'ewn 

 abundantly on, the west slope of a hill of the Fort Pierre shale which rises 

 nearly on the line between sections 32 and 33, township 139, range 58, to a 

 height 50 feet above the average of the adjoining country, or about 225 feet 

 above the river. Thence the moraine appears to turn northeastward and 

 to lie concealed across a distance of abovit 4 miles beneath the high flood- 

 plain of gravel and sand adjoining the Sheyenne, out of which the apex of 

 a sharply reentrant angle projects in two typically morainic hills about 40 

 feet high in or near section 12 of this township, some 2 miles east of the 

 river. Returning thence west-southwestward to the prominent and massive 

 hill in the north part of section 19 of this township 139, range 58, 2 miles 

 west of the river, abundant bowlders, apparently marking the course of the 

 ice front at the time of the Dovre moraine, are strewn over the east, north- 

 east, and southwest sides of this hill, which, however, is principally a 

 rounded pi'ojection or boss of the Fort Pierre shale, seen in the slight 

 ravines of its east side to 40 feet below its top. The higher part of its 

 southwesterly sloping but somewhat plateau-like top, less encumbered
