CLEVELAND MORAINE. 635 



the soxitli end of the lake to French Creek, and it is reported that in times 

 of high water the lake discharges southward as well as northward, bnt the 

 main outlet is to the north, through North French Creek. 



For several miles northeast from Findley Lake the )noraine is on 

 elevated upland, and consists of scattering knolls 10 to 20 feet high, but 

 from the valley east of Mina Corners to Lake Chautauqua knolls 20 to 40 

 feet in height abound. Some of these are abrupt, but the majority have 

 gentle slopes. 



On the east side of Lake Chautauqua the drift bench above referred 

 to may be traced from near Point Whitesides down to the southeast end of 

 the lake, but is not well developed farther up the lake shore. The surface 

 of the di-ift bench is gentl}^ undulatory, with swells 5 to 10 feet high, and 

 ranges in height from 40 feet or less up to about 80 feet above the lake. 

 In a few places shallow basins are present, the deepest being about 5 feet. 



The eastern tributaries of Lake Chautauqua have, as a rule, smooth 

 slopes, and the uplands between the valleys of Lake Chautauqua and Cas- 

 sadaga Creek carry remarkably few drift knolls. 



In Cassadaga Valley a drift bench standing 40 to 50 feet above the 

 broad bottom is conspicuous from near South Stockton down the valley 3 

 or 4 miles on each side of the stream, but is not well developed farther 

 south. There is, however, a similar bench near the junction of the creek 

 with the Chautauqua outlet, which forms a southern limit for the broad 

 bottom. The bench at the mouth carries numerous basins, but that farther 

 up the valley is characterized by low swells rather than basins. 



The drift deposits in Mill Creek Valley are irregular aggregations, in 

 places nearly filling the valley to a height of 60 to 80 feet above the stream, 

 in other places merely dotting its slopes with knolls. Occasionally the 

 knolls occur at a height of 150 to 200 feet above the valley bottom. 



The drift deposits in "Farrington Hollow" rise 50 to 75 feet above the 

 stream, and vary from sharp knolls to nearly plane-surfaced deposits. The 

 deposits in West Couewango Valley at Hamlet are sharp, gravelly knolls 

 50 to 75 feet in height, but east of Hamlet the surface is nearly level. 



The bench on the borders of Conewango Valley is conspicuous from 

 Cherry Creek southward on each side of the valley as far as Kennedy. It 

 generally stands 40 to 50 feet above the broad bottom, is gently undulating, 

 and carries a few basins.
