WABASH MORAINE. 547 



to the map (PI. XI) it will be seen that sti'eams in northwestern Ohio and 

 northeastern Indiana usually flow either parallel with or at right ang-les to 

 the trend of the moraines. In both cases the coiu-se plainly results from 

 slopes due to drift aggregation. This is true of the Mississinawa, the 

 Salamonie, the Wabash, the St. Marys, the St. Joseph, and the Auglaize 

 rivers, as well as of several smaller streams. Attention is here called only 

 to such as have their courses controlled by the Wabash moraine. The 

 westward-flowing portion of Sandusky River, the eastward-flowing por- 

 tion of the Scioto, and the westward-flowing portion of the headwaters of 

 Auglaize and St. Marys rivers and Big Beaver Creek are all controlled by 

 this moraine. The Wabash above Fort Recovery has its com-se governed 

 by the Salamonie moraine ; the river then flows northward for several miles 

 as if to discharge into the Maumee River, but upon reaching the outer 

 border of the Wabash moraine it is turned westward, and instead of flowing 

 into the Maumee and becoming a part of the St. Lawrence drainage basin, 

 it passes westward to the old lake outlet at Huntington, and eventually 

 discharges into the Grulf of Mexico. Had a suitable break occurred in the 

 Wabash moraine, either in western Ohio or eastern Indiana, the upper 

 portion of this stream might have become a part of the St. Lawrence 

 system. 



Blue Creek, in Adams County, Ind., after flowing for several miles 

 parallel with the inner border of the moraine, and distant but 4 or 5 miles 

 from the Wabash River, turns abruptly northeastward and discharges into 

 the St. Marys River. 



In Wells County, Ind., two small streams flow along the inner border 

 in opposite directions, but parallel with the moraine, when they find a 

 break which permits their passage through it into the Wabash near Bluff- 

 ton. The bends in Eightmile Creek, in Wells County, between Ossian and 

 Zanesville, are also determined by the morainic ridges. 



The southwestward com'se of Big Cedar Creek, in Dekalb County, 

 from near Auburn to northern Allen County, is due to the presence of the 

 moraine. The creek then flows in a southeastward course, or almost 

 exactly at a right angle to the coui'se above this bend.
