TERMINAL MORAINES. 211 



movement was directly toward the head of the Maumee 

 River. 



The general system of interior moraines upon which we 

 were remarking is pretty well exhihited about the eastern 

 shore of Lake Michigan, forming a grand loop around that 

 lake, and connecting with two subordinate loops around the 

 head of Grand Traverse Bay and Saginaw Bay. But it is not 

 until reaching the country west of Lake Michigan, in Wis- 

 consin, that these glacial accumulations become again a very 

 prominent feature of the landscape. Here they constitute 

 the so-called Kettle Range, which forms a loop pointing to 

 the southwest in the line of the longer axis of Green Bay. 

 President Chamberlin has shown * that the ice-movement to 

 the southward through Green Bay was in a measure inde- 

 pendent of that through Lake Michigan ; so that the eastern 

 arm of the Kettle Range might more properly be called a 

 medial moraine, to which the Lake Michigan Glacier and the 

 Green Bay Glacier both contributed their deposits. This 

 eastern arm runs about half-way between Fond du Lac and 

 Sheboygan, and thence a little west of south, through Wash- 

 ington and Waukesha counties, between Oconomowoc and 

 Pewaukee, and through Eagle to Milton, between Janesville 

 and Whitewater. Thence it swings northward, passing a few 

 miles west of Madison, and, crossing an elbow of the Wiscon- 

 sin River, incloses in its folds Devil's Lake, near Baraboo, 

 and thence on northward into the wilderness of northern 

 Wisconsin, a little beyond the latitude of St. Paul, where it 

 turns westward and with some deflection reaches the St. Croix 

 River at Hudson, a few miles above its junction with the 

 Mississippi. From this point it trends southward past Min- 

 neapolis through southeastern Minnesota, inclosing in its 

 folds Minnetonka and many other beautiful lakes in that 

 portion of the State. From this point on, Mr. Upham has 

 traced the moraine in an ox-bow-shaped extension, whose
