122 PLEISTOCENE OF INDIANA AND MICHIGAN. 



by the ice sheet, but the fact that these valleys lead west of south, or about in the direction of 

 ice movement as shown by strife, renders it somewhat improbable that the undulatory belts 

 mark the trend of the ice margin. 



Wildcat Creek west from Kokomo has a valley 40 to 70 feet deep, the depth increasing 

 toward the west. The bluffs are about as high as the land north of the creek, but are lower 

 than the land south of the creek, for the plain rises 10 to 15 feet to the mile from the bluffs 

 southward to the crest of the great drift belt in southwestern Tipton and southern Clinton 

 counties. As a result the tributaries from the south are long and the country they traverse 

 is well drained, but on the north they are trivial and the greater part of the plain for 3 to 5 

 miles north of the creek in Howard County is poorly drained.
