ST. MARYS OR FORT WAYNE MORAINE. 571 



an east-northeast to west-southwest direction — i. e., in line with tlie trend 

 of the moraine — but only for about a half mile in a place, the belt in that 

 vicinity being generally without distinct ridge or crest. 



In the valley to the west, in which Chippewa Lake lies, the moraine 

 has scarcely as many knolls as are found on the uplands, and, so far as 

 observed, they are all low — 15 feet or less in height. 



From Chippewa Lake southwestward to Burbank the moraine has a 

 patchy development, being interrupted by broad marshy tracts on the low- 

 lands and but feebly developed on the uplands Upon leaving Killbuck 

 Creek, near Burbank, its expression becomes stronger, and throughout 

 much of the distance westward to the Scioto-Sandusky Basin it has greater 

 strength than the Wabash moraine and is less in-egular in its features. Its 

 surface is billowy, being seldom sharply ridged. The knolls are 10 to 25 

 feet in height and so closely associated as to leave but little plane surface 

 among them. 



From Lake Fork westward to Plymouth the Fort Wayne lies imme- 

 diately north of the Wabash moraine; but east from Lake Fork it is quite 

 distinct from the Wabash belt for several miles, there being a nonmorainic 

 interval 1 to 3 miles Avide, and westward from Plymouth it is distinct all 

 the way to the Sandusky River, there being a plain 1 to 3 miles wide 

 between the moraines, through the midst of which Brokensword Creek 

 has its course. 



From Plymouth westward to the Sandusky River the Fort Wayne 

 moraine has frequent developments of ridges which correspond in treiid 

 with the course of the moraine, being nearly east to west in the vicinity of 

 New Washington and Chatfield and northeast to southwest a few miles 

 farther west, near Seal, where the moraine curves toward the southwest. 

 It has also numerous knolls 10 to 20 feet high and a well-defined and, in 

 places, very abrupt outer border relief of 20 to 30 feet. This portion of 

 the moraine is in strong contrast with the ver}" flat tracts that border it on 

 either side. 



From the curving portion of the moraine, near Seal, a spur runs out 

 to the northwest or nearly at a right angle to the trend of the moraine. 

 It occupies much of the interval between Sycamore Creek and Sandusky 

 River, a breadth of 4 or 5 miles, and extends to the bend of the Sandusky at 

 McCutcheonAdlle, a distance of fully 10 miles from the inoraine, where it
