WABASH MORAINE. 563 



with the morames of the Scioto lobe. It is necessary here to consider only 

 the valley drift phenomena, which have a bearing npon the drainage of the 

 ice sheet at the time the moraine was forming. In some of these valleys, 

 as will appear from the description, the evidence of ontwash from the ice 

 sheet is clear and unmistakable, while in others the phenomena are less 

 clear in their import. 



The easternmost valley through which the glacial waters could have 

 found escape to the southward is the one passing from the bend of the 

 Cuyahoga tlu'ough the cit)^ of Akron to the Tuscarawas River, crossing the 

 Lake Erie-Ohio divide at Summit Lake This valley carries heavy deposits 

 of gravel and sand that are of glacial age, a portion of its gravel plain being 

 indented with deep basins such as often characterize the ontwash aprons 

 along moraines, and which are not known to occur except in glacial deposits. 

 The valley has evidently at some time been the avenue for the discharge of 

 glacial waters, but on account of the great amount of erosion which has 

 taken place in it near the bend of the Cuyahoga the connection with the 

 morainic series under discussion is not clear. It may possibly be of greater 

 age. A chain of knolls and ridges of morainic type occurs along the western 

 border throughout nearly its entire course, which, though forming a very 

 feeble moraine, may indicate the position that the ice margin occupied while 

 the gravel plain was being formed. The northernmost occurrence of the 

 gravel plain is found in a remnant north of the city of Akron, a very level 

 tract extending southward from the bend of the Cuyahoga along the east 

 side of the Little Cuyahoga to the northern part of the city (Akron on the 

 Heights), where it is cut oif by the Little Cuyahoga Valley. Its altitude is 

 about 1,000 feet above tide. It reappears on the south side of the Little 

 Cuyahoga, passing through the western part of the city, along the west side 

 of the Ohio Canal. In this portion it is characterized by numerous basins, 

 which are most abundant on its western border next the chain of morainic 

 knolls just referred to. Farther south it is followed by the canal and extends 

 some distance to the east of it, and includes larger basins, a few of which 

 contain water, as Summit Lake and a chain of lakes leading south from 

 there to the Tuscarawas River. 



A valley just west of Akron, leading southward through Copley Marsh 

 to the Tuscarawas from near the head of the Cuyahoga, has gravel deposits 

 in it that head in the morainic series on the continental divide. The
