314 THE GLACIAL LAKE AGASSIZ. 



Surface at Charles G. Froemke's house, in the northwest quarter of 

 section 29, township 135, range 54, 1,075 feet; ))ottoni land of the Sliey- 

 enne River close west, 1,039 to 1,029 feet; ordinary low water of the 

 river, 1,021 feet. 



Portion of area of Lake Agassiz, a strip a fourth to a third of a mile 

 wide, west of the Sheyenue River, in sections 32 and 5, a half mile to 2 

 miles south of Mr. Froemke's, 1,065 to 1,075 feet. Herman beach one- 

 fourth to two-thirds of a mile east of the Sheyenne River here and extend- 

 ing southeasterly toward the western limit of dunes in the east pail of 

 township 134, range 54, 1,073 to 1,079 feet. Crest of this beach, a low 

 ridge of sand and fine gravel, at J. Altmann's house, near the middle of 

 section 20, township 135, range 54, 1,073 feet. Within 10 or 15 rods east 

 there is a descent of about 10 feet. This beach ridge runs north and 

 northeastei'ly to near the northeast corner of this section 20, and thence it 

 passes eastward about 3 miles, having an elevation of 1,075 to 1,065 feet 

 to where it is intersected by the Sheyenne River, near the northeast corner 

 of section 14. North of the river it continues about a lialf mile in section 

 12, its elevation being 1,065 to 1,070 feet, to the west end of a tract of 

 dunes 25 to 100 feet above their vicinity, with summits at 1,100 to 1.150 

 feet, which extends thence about 15 miles eastward. This Herman beach 

 was sufficient to turn the coiirse of the Sheyenne River along its west and 

 north side for a distance of 8 miles, from section 9, township 134, range 54, 

 north and east to section 14, township 135, range 54, though it is only a 

 ridge of sand and gravel 5 to 1 feet higher than the smoothed area of till, 

 occasionallv covered l)y 1 to 3 feet of sand, which lies west of it and in 

 which the river has now cut its channel 50 to 60 feet deep. 



Rolling surface of till in the south edge of section 9, township 135, 

 range 54, 25 to 40 rods north of the Sheyenne River, 1,080 to 1,090 feet. 

 Most of this section 9 is nearly level till at 1,080 to 1,085 feet, with occa- 

 sional large hollows 20 feet lower. It seems to have been smoothed by 

 Lake Agassiz at the time of the Milnor beach. Westward is slightly undu- 

 lating till, having an elevation of 1,085 to 1,125 feet for 2 or 3 miles, as far 

 as the sm-face lies within ^^ew.
