THE iSlXTH OK WACONIA MORAINE. 143 



After passing northwest aoross Lake Traverse and the Head of the 

 Coteau des Prairies, the Waconia moraine appears to be merged with the 

 two preceding Elysian and Kiester moraines in the conspicuous belt of 

 drift liills that extends from the line dividing South and North Dakota 

 northward between Straubville and Crescent Hill, between Nicholson and 

 Oakes, and along the east side of Bear Creek, to the southeast pai't of 

 township 135, range 69. Thence it tin-ns west and noi-thwest a few miles, 

 beyond which it runs again northward through the west part of township 

 136, range 59, the most northeastern of Lamoure County, where it forms 

 a narrow belt of knolls and hills, rising 40 to 60 feet above the nearly 

 level plain on each side. 



In Barnes County, running 42 miles from south to north, this moraine 

 is distinct and well developed, being divided from the next earlier and later 

 moraines of the series b)^ smoothly' undulating and in large Y)avt nearly 

 level belts of till, which vary in width from 2 to 3 miles to a maximum of 

 about 8 miles on the west and 12 miles on the east, the separation from the 

 seventh or Dovre moraine being on the average the wider of the two. 

 The Waconia moraine enters Barnes County at the middle of the south 

 side of township 137, range 59, and curving norfheastward passes through 

 sections 34, 2G, and 24, in a belt of typical knolls and hills 25 to 75 feet 

 high, very rough in their outlines and profusely strewn with bowdders, to 

 the east line of this township, where the apex of a reentrant angle of this 

 belt almost touches tlie Dovre moraine, which rises to equal or greater 

 prominence in the adjoining township. A plain of overwashed gravel and 

 sand, depo.sited just outside the ice border in the indentation of the Waconia 

 moraine, is crossed by the road on the west line of sections 23, 14, and 11, 

 township 137, range 59, thinly covering the underlj'ing till, which is occa- 

 sionally exjjosed, with its projecting bowlders, in slight depressions. Turn- 

 ing by a right angle, this moi-aine runs northwestward through sections 13, 

 11, and 3, rising 25 to 60 or 75 feet above the general level. In the north- 

 east quarter of section 3, a lake bed, wholly dry in August, 1889, lies at 

 the northeast base of these liills, and a belt about a half mile wide, next to 

 the north, is modei'ately rolling till, beyond which a second belt of morainic 

 hills similar to the foregoing and parallel with it, a fouitli to a third of a
