Wisconsin Ktitle Moraine. 219 



mated altitude of 200 feet or more above the surface of the beau- 

 tiful lakelets embosomed at their base. The deep cuts near the 

 latter station, amply exhibit the coarse, commingled material, 

 characteristic of the core of the range. 



Putting the foregoing observations together, thej seem to es- 

 tablish beyond reasonable doubt the existence of a broad, massive 

 belt stretching northeastward on the highland between the Sagi- 

 naw and Erie basins. 



If we return again to the southwestern part of the state, we 

 are informed by Dr. Boughton that we shall find a similar accu- 

 mulation at, and in the vicinity of, Kalamazoo. To the north- 

 northeast, in Barry county, the Thorn Apple river cuts across this 

 range between Sheridan and Middleville. This belt here, though 

 broad, presents a more prominent and ridge-like aspect, with bet- 

 ter defined limits than elsewhere observed in Michigan. To the 

 north of this, opposite Saginaw bay, there occurs, near Farwell, 

 broken, rough country and abundant coarse drift, that probably 

 belongs to the belt in question, but my opportunity for observa- 

 tion was unsatisfactory. Beyond this point, I have no definite 

 information, but I deem it highly probable that the moraine will 

 be found extending some distance farther, on the highlands of the 

 Peninsula. 



The lake survey charts show that Grrand Traverse bay has the 

 remarkable depth of over 600 feet. This great depth, together 

 •with its linear character, and the form and arrangement of the 

 associated inlets and lakes, has suggested that it may have been 

 the channel of a separate minor glacier, analogous to that of 

 Grreen Bay on the opposite side of the great lake, but I have no 

 direct evidence that such was the fact. 



In the reports of the geological survey of Ohio, a formation of 

 nearly, or quite, identical characteristics is carefully described bj 

 the several writers whose districts embraced it. In the second 

 volume,^ Dr. Newberry gives, under the name of " Kames," an 

 excellent summary of its leading features. These harmonize very 

 nearly with those of the Kettle belt. The main points of diiler-
