THE UPPEK OR HERMAN BEACHES. 327 



with a depression on tlie west. 4 to 6 feet below its top, wliich lias an eleva- 

 tion of 1,120 to 1,123 feet. Novtliward in section 7, this beach, continuing 

 at 1,120 to 1,123 feet, is quite broad, without a distinctly ridged form, and 

 is indented from the east by a large slough, whose elevation is approximately 

 1,100 feet, including several acres of water free from grass and rushes. 

 Crest of beach in the southwest quarter of section 6, Galesburg, 1,122 to 

 1,126 feet; through sections 31 and 30, Norman, 1,125 to 1,129 feet; and 

 in the west half of section li), 1,127 to 1,124 feet, sinking slightly from 

 south to north. The farther course of this shore is not marked by con- 

 tinixous beach deposits; but, following the contour line of 1,12.5 feet, it 

 must turn west in the southwest quarter of section 18, Norman, and extend 

 through sections 13 to 6, township 145, range 54, to the South Branch of 

 Goose River. 



Natural surface at the southwest corner of section 3, township 145, 

 range 54, a dozen rods west of the South Branch of Goose River, 1,104 

 feet. This stream, about 1,070 feet, is 8 to 20 feet wide and mostly 1 to 2 

 feet deep. Its bottom land, 5 to 10 feet above this stage of low water, 

 varies from 20 to 100 rods in width and is inclosed by bluffs rising 30 to 

 50 feet, increasing in height southwestward. The valley has no timber, the 

 largest wood growth being willows 5 to 8 feet high and 2i inches or less 

 in diameter. With the aid of these, however, .beavers had constructed 

 dams, and were living on this stream when this survey was made in 1885, 

 one of their dams then occupied being found by my assistant, Mr. Robert 

 H. Young, in the west edge of section 10, township 145, range 54. 



Floor of Henry Bentley's barn, in the southwest corner of the southeast 

 quarter of section 6, township 145, range 54, on the Herman shore of Lake 

 Agassiz, 1,123 feet. This is a moderate slope, ascending 12 or 15 feet, 

 eroded in till, which from its top stretches westward about 2 miles in a 

 neai-ly level expanse. From the south side of section G, such a low escarp- 

 ment, with its top at 1,120 to 1,123 feet, extends due north, or a few degrees 

 west of north, about 5 miles. 



E. W. Palmer's house, in the northwest corner of the southwest quarter 

 of section 2, township 145, range 55, 1,145 feet. Well here, 27 feet deep: 

 soil and very hard gravel and sand, 2 feet; sand with occasional layers of
