HEEMAN SHOEE WEST OF THE ELK VALLEY. 339 



seen from the margin of Lake Agassiz, being hidden in the valley, 40 to 

 50 feet deep, which the stream has eroded in that area of nndulating and 

 rolling till. 



Herman beach, for tlie first mile or more north from Bachelors Grove, 

 passing through the northwest quarter of section 30 and the west edge of 

 section 19, Agnes, 1,165 to 1,170 feet. This is mostly a well-defined beach 

 ridge, 20 to 30 rods wide, composed of sand and gravel, with pebbles up 

 to 2 inches in diameter. It rises slowly to a height of 10 or 12 feet above 

 the flat land on the east and is bordered on the west by a depression of 1 

 to 3 feet, beyond which a smoothly undulating and rolling surface of till 

 rises to an elevation of 1,200 and 1,250 feet at a distance of 3 miles. In 

 the northwest quarter of this section 19 the beach deposit becomes complex, 

 consisting of several irregular ridges rising 5 to 8 feet above their bases, 

 1,167 to 1,170 feet above sea-level, with inclosed hollows, and the depres- 

 sion close west occasionally sinks to 1,165 feet. 



Thi-ough sections 13 and 12, the southwest part of section 1, and in 

 section 2, Oakwood, to the grove on the north line of section 2 at the 

 junction of the north and south branches of Lost Creek, and thence north- 

 east and north through section 35, Elkmount, the Herman shore, between 

 1,160 and 1,170 feet, is not marked by any considerable deposits of gravel 

 and sand. Farther north this shore is distinguished not only by a notice- 

 able change in the topographic features along a nearly level line at 1,170 

 feet, dividing the very flat area of the glacial lake from the undulating and 

 rolling till on the west, but also by occasional beach deposits. Through 

 the south half of section 26, Elkmount, a somewhat typical beach ridge of 

 sand and gravel, 15 to 25 rods wide, with a depression of 3 to 6 feet on its 

 west side, runs north and northwest, its crest being at 1,175 to 1,170 feet, 

 declining from south to north. On the east its slope falls 6 to 10 feet in 10 

 to 20 rods; and thence a more gentle descent, with surface of sand and fine 

 gravel, sinks to 1,155 feet within an eighth of a mile. In the northwest 

 quarter of this section 26 the beach ridge ceases and is succeeded north- 

 ward by an expanse of nearly flat till, which along the north line of this 

 section sinks eastward from 1,175 to 1,155 feet.
