 having never been filled.

CLEVELAND MORAINE. 



The Cleveland moraine is the next one later than the Defiance. As a 

 land-laid moraine it appears to be developed no farther west in Ohio than 

 the southwestern part of the city of Cleveland, but its continuation as a 

 water-laid moraine may be traced at points west from Cleveland. Possi- 

 bly it will be found near a line recently suggested by Taylor, a short 

 distance back from the shore of Lake Ei'ie from Cleveland to Toledo, and 

 thence northward into Michigan; it would then perhaps be more appropri- 

 ately termed the Toledo moraine, a name suggested by Taylor.^ Neither 

 Taylor nor the writer has, however, found conclusive evidence of a moraine 

 along the portion of the line between Cleveland and Toledo, nor for some 

 distance north from Toledo. This being the case, it seems preferable to 

 withhold the name Toledo and apply the name Cleveland, the latter being 

 a prominent city at the southwestern end of the well-defined land-laid por- 

 tion. This land-laid portion has occasionally been called the Newburg 

 moraine, from the part of Cleveland in which it is found, but it seems pref- 

 erable to substitute the name of the well-known city rather than to adopt the 

 name of one of its suburbs. 



DISTRIBUTION. 



The westernmost point at which this moraine has been recognized is 

 on the west bluff of Big Creek, opposite North Linndale, near the south- 

 western limits of the city of Cleveland. To the south, west, and north 

 of this place there is a very level surface, on which no morainic features 

 were detected. From North Linndale the course of the moraine is nearly 

 due east along the south side of Big Creek to its junction with the Cuya- 

 hoga in the southeast part of Cleveland. Upon crossing the Cuyahoga 

 into the part of the city known as Newburg, the moraine, as indicated in 

 PI. XIII, continues eastward through Randall to the valley of Chagrin 

 River below Chagrin Falls. From this valley the moraine swings abruptly
