296 F. Leverett — Correlation of Moraines 



not seem to be sustained. I am inclined to correlate the lower 

 of the two terraces, with the Belmore beach, since the altitude 

 is not too great for that stage of the lake, and to leave the 

 question open as to whether or not the lake extended back to 

 the upper terrace at the time it was forming the Leipsic beach. 

 That the lake at the time of the Leipsic beach did not extend 

 farther east than Cleveland has been determined by Mr. 

 Gilbert who has given the beaches of the eastern end of the 

 Erie basin careful study. 



(h) The Correlative Moraine of the Leipsic Beach. — This 

 moraine as indicated above is traceable no farther west than 

 North Linndale. Both north and west from there the surface, 

 aside from the low beaches, is a monotonous plain with scarcely 

 any undulation. The disappearance of the moraine at the 

 point where the beach appears, leaves little room for doubt 

 that the ice-sheet here terminated in a lake and that the beach 

 is of glacial age. The portion of the moraine west of the 

 Cuyahoga does not show evidence that it was deposited in lake 

 water, on the contrary its structure so far as exposed opposes 

 such a theory of deposition, the mass of the ridge being ordi- 

 nary till without capping of sand or other water deposits. But 

 since the descent is rapid toward the Lake Erie basin from the 

 junction of the beach and moraine, there was sufficient depth 

 of water to cause the ice-sheet to break up into bergs at its 

 margin instead of resting upon the lake bottom and forming- 

 such a moraine as it did in the western Erie basin northward 

 from the junction of the Van Wert beach and Blanchard 

 moraine. 



Tracing the moraine eastward we find it passing just south 

 of the village of Brighton near which it is interrupted by the 

 Cuyahoga valley. It reappears on the east side of the river in 

 Newburg and is traceable from there eastward through Randall 

 and Warrensville to the Chagrin river below Chagrin Falls. 

 Its farther course may be seen on the general map (fig. 1). 

 West of the Cuyahoga it is a single gently undulating ridge 

 about 80 rods in width and 20-30 feet in height. East of the 

 river it consists of many short ridges and conical swells 10-25 

 feet in height and has a width of 1-2 miles or more. In 

 places there is a well defined crest but as a rule the crest is 

 wanting. 



The range of altitude is considerable. West of the Cuya- 

 hoga the moraine stands about 800 feet A. T. East of the 

 river it rises from 800 feet at ISTewburg to 1050 feet at Randall 

 (only six miles distant), and ranges up and down 200-250 feet 

 in eastern Cuyahoga and Geauga counties in crossing ridges 

 and valleys, its highest points being about 1250 feet A. T.
