MISSISSINAWA MORAINE. 495 



eastern border of the interlobate belt would seem to indicate that the con- 

 tinuation of the Mississinawa moraine lies within the interlobate belt, but 

 the ver}^ strong- contrast in topography between the terminal loop and the 

 rugged portion of this interlobate moraine leads the writer to question 

 whether the latter belt should be considered the continuation of the former. 

 Were the evidence clear that the Saginaw and Maumee lobes were both in 

 this field at the time the Mississinawa moraine was forming, conditions 

 might have been favorable for producing this rugged belt and the striking 

 change in topography, but all the evidence yet obtained fi-om outwash 

 and courses of glacial drainage apparently opposes the view that the Sagi- 

 naw lobe was at that time occupying the western side of the Indiana portion 

 of the interlobate moraine, and indicates that the western side was an open 

 country free from ice, across which Pigeon River carried the waters from 

 the melting Maumee ice lobe. The writer is inclined to believe that the 

 continuation of the Mississinawa moraine is along a Hue outlined by Dryer 

 as the course of the Sala.mouie or "Third Erie" moraine, both moraines being 

 crowded into the one belt. This belt is much stronger than the portion of 

 the Salamonie moraine immediately south of the Wabash River, where it 

 becomes distinct from the Mississinawa moraine, and though somewhat less 

 bulky than the terminal loop of the Mississinawa it may well be considered 

 the equivalent of both moraines, since it was formed on the northwestern 

 border of the ice lobe, where the movement would naturally be more feeble 

 and the moraines less bulk}^ than on the southern margin of the lobe. The 

 course of this belt lies along the eastern border of the interlobate moraine 

 from Columbia City to northern Dekalb County, passing just west of Gari-ett 

 and Waterloo. It here swings eastward a few miles, then bears northward 

 along the State line and enters Michigan near the corner common to 

 Indiana, Ohio, and Michigan. Its course and connections in the latter 

 State are under investigation. 



East of the head of the Mississinawa, in Darke County, Ohio, the 

 moraine is found to present a slight looping or southward projection in 

 harmony with earlier moraines of the Maumee-Miami lobe. Its southern- 

 most point is at Versailles, from which village its course is north of west to 

 the head of the Mississinawa, and north of east to the divide between the 

 Scioto and the Great Miami in southern Hardin County. On this divide it 

 becomes associated with the St. Johns or Salamonie moraine on the north 

 border and with the Union moraine on the south. The combined belt soon
